Sarcoid Uveitis

Sarcoid uveitis is eye inflammation that happens when a person has sarcoidosis, a condition where the immune system forms tiny clumps of inflammatory cells called granulomas in different organs, including the eye. In the eye, this inflammation can sit in the front of the eye, the middle gel, the back of the eye, or in all of these places at once, and the inflammation can be mild and short-lived or deep and long-lasting. Doctors recognize sarcoid uveitis because certain signs in the eye are very typical, such as big greasy-looking deposits on the back of the cornea, small bumps on the colored part of the eye, clumps or strands of white cells in the eye gel, inflammation around retinal veins that can look like melted candle wax, and sometimes yellowish lumps under the retina called granulomas. These patterns, together with blood tests and scans and sometimes a tiny biopsy, help confirm the diagnosis after other causes like tuberculosis and syphilis are ruled out. EyeWiki+1NCBI

Sarcoid uveitis means inflammation inside the eye that happens in a person who has sarcoidosis, an immune condition where the body forms tiny clusters of inflammatory cells called granulomas. These granulomas can appear in many organs—most often the lungs, lymph nodes, skin, and eyes. When they affect the uvea (the eye’s blood-rich middle layer that includes the iris, ciliary body, and choroid), they cause uveitis. Uveitis can be anterior (front of the eye), intermediate, posterior (back of the eye), or panuveitis (all parts). The inflammation makes the eye red, painful, and light-sensitive, and may blur vision or cause floating spots. If inflammation is not calmed down, it can lead to complications such as high eye pressure (glaucoma), cataract, or swelling in the central retina (cystoid macular edema). Doctors treat sarcoid uveitis by quieting inflammation, protecting vision, and preventing flares using a ladder of therapies—from local steroid eye drops to steroid injections or implants, to oral steroids, and, when needed, steroid-sparing immunomodulatory medicines (like methotrexate or biologics). Eye specialists often coordinate with lung or rheumatology teams because sarcoidosis is a whole-body condition. Corticosteroids are first-line, but many people need steroid-sparing treatment to limit long-term steroid side effects. MDPI

Types

1) By where the inflammation sits in the eye

• Anterior sarcoid uveitis means the inflammation is mainly in the front of the eye, and doctors may see large “mutton-fat” deposits on the back of the cornea, iris bumps called Koeppe or Busacca nodules, and sticky adhesions between the iris and the lens. This can raise the eye pressure when the drain becomes inflamed or clogged. EyeWikiMDPI

• Intermediate sarcoid uveitis means the inflammation sits mostly in the middle of the eye, where the clear gel (vitreous) lives, and the white cells gather as “snowballs” or line up like a “string of pearls.” This pattern is very suggestive in sarcoidosis. Review of Optometry

• Posterior sarcoid uveitis means the back of the eye is involved, and doctors can see inflammation of retinal blood vessels, the classic “candle-wax drippings” along veins, leakage from the optic nerve, or choroidal granulomas that can blur central vision if they sit near the macula. EyeWiki

• Panuveitis means the inflammation involves the front, the middle, and the back of the eye at the same time, which is common in sarcoidosis and can be sight-threatening if not controlled. EyeWiki

2) By diagnostic category (IWOS criteria)

• Definite ocular sarcoidosis means the eye picture looks like sarcoidosis and there is a tissue biopsy somewhere (eye or body) that shows the classic non-caseating granulomas, and other causes have been excluded.

• Presumed ocular sarcoidosis means the eye signs look right and chest imaging shows bilateral hilar lymph node enlargement, but the biopsy did not confirm sarcoidosis.

• Probable ocular sarcoidosis means the eye signs plus certain lab or imaging markers make the diagnosis likely when biopsy is not available. These categories come from the International Workshop on Ocular Sarcoidosis (IWOS), last revised in 2019, and they help standardize how doctors label and study this disease. PubMedEyeWiki

3) By time course

• Acute uveitis means it starts quickly and settles within a few months, sometimes returning in episodes.

• Chronic uveitis means it lingers beyond three months, often waxes and wanes, and often leaves stains of inflammation that doctors can still see even when the eye is quieter.

4) By laterality

• Sarcoid uveitis is often in both eyes, but one eye can start first and the other may follow later, and the two eyes do not always flare with the same strength. EyeWiki

Causes and contributors

The exact cause of sarcoidosis, and therefore sarcoid uveitis, is unknown, but research points to a mix of genetic susceptibility, immune over-activation, and environmental or microbial triggers. The items below are worded as “contributors” because no single factor explains every case.

1. Immune mis-direction: the immune system overreacts and builds granulomas that do not dissolve, especially with Th1/Th17 pathways and cytokines like TNF-α and IFN-γ, which keep inflammation going in sensitive tissues like the eye. MDPI

2. Genetic susceptibility (HLA variants): certain HLA-DRB1 patterns and immune-related genes such as BTNL2 and ANXA11 raise the chance of developing sarcoidosis and shape which organs get involved. Archivos de BronconeumologíaFrontiersPMC

3. Family influence: having a close relative with sarcoidosis slightly increases risk, which supports the idea of inherited immune traits. PMC

4. Cutibacterium (Propionibacterium) acnes: fragments of this skin commensal have been found in granulomas in some studies, and it is a suspected trigger in genetically primed people. MDPI+1

5. Mycobacterial antigens: proteins from mycobacteria (for example ESAT-6 or KatG) may stimulate persistent T-cell responses in some patients, which could help start granuloma formation. SpringerOpen

6. Other microbes: reports also implicate herpes viruses, retroviruses, Borrelia, or Leptospira as possible immune sparks in rare cases. SpringerOpen

7. Inorganic dusts: silica and other dusts can provoke granulomatous immune activity and are linked to higher sarcoidosis-like illness in exposed workers. PMC

8. Combustion smoke and disaster dust: smoke and complex dust (for example, some firefighters exposed during large fires) have been associated with later sarcoid-type illness in observational studies. PMC

9. Foreign materials: silicone implants and other persistent materials have, in some reports, been linked to granuloma formation that mimics or triggers sarcoid-type reactions. PMC

10. Beryllium exposure: chronic beryllium disease is not sarcoidosis but can look very similar; this highlights how certain metal exposures can push immune systems toward granuloma formation. PMC

11. Overweight and obesity: extra fat tissue can drive pro-inflammatory signals (for example leptin), which may amplify immune reactivity and granuloma persistence. PMC

12. Sex and ancestry: patterns differ by sex and ancestry, suggesting that hormonal and genetic backgrounds change risk and shape clinical pictures. ScienceDirect

13. Gut-immune cross-talk: early research suggests the gut microbiome may nudge immune balance toward granuloma building in a subset of patients. SpringerOpen

14. Checkpoint-inhibitor immunotherapy: cancer drugs that remove immune brakes can trigger sarcoid-like reactions that sometimes involve the eye. PMCOxford Academic

15. Anti-TNF drugs (paradoxical): medicines that block TNF-α—oddly—can rarely cause a sarcoid-like disease in some patients, which improves when the drug is stopped. PMCLippincott Journals

16. Interferon therapies: interferon-α and other immune-stimulating treatments have been linked to sarcoid-like granulomas in case series. ScienceDirect

17. Chronic antigen exposure: ongoing contact with poorly cleared particles or microbes can keep antigen-presenting cells busy, which keeps T-cells activated and makes granulomas more likely to persist. MDPI

18. Local tissue factors in the eye: the uveal tract is rich in blood supply and immune cells, so once systemic sarcoid inflammation is present, the eye can become a favored site for granuloma buildup. (Concept supported across ophthalmic reviews.) PMC

19. Age-related immune patterns: sarcoidosis most often starts in young to middle-aged adults, an age when robust cellular immunity may amplify granuloma building. (General epidemiologic observation in reviews.) PMC

20. Co-existing autoimmune tendencies: some people with sarcoidosis have other autoimmune features, and this broad immune “readiness” may make eye involvement more likely when sarcoid flares. (Synthesis from multisystem reviews.) PMC

Symptoms

1. Blurry vision: the world looks foggy because inflammatory cells and protein float in the eye fluid and because swelling often hits the macula.

2. Floaters: you see spots or cobwebs drifting because white cells form clumps in the gel.

3. Eye redness: the white of the eye looks pink or red from inflamed surface blood vessels.

4. Eye pain or ache: the front of the eye is inflamed and the ciliary body is irritated.

5. Light sensitivity: bright light hurts because the inflamed iris and ciliary body react to light.

6. Tearing or watery eye: irritation drives reflex tearing, and the tear gland can also be involved in sarcoidosis.

7. Halos or glare: cornea swelling and protein in the eye fluid can scatter light and make halos.

8. Reduced contrast or color: inflammation and macular swelling lower crispness and color punch.

9. Distorted straight lines: macular swelling from cystoid macular edema makes lines bend or ripple. PMC

10. Patchy or side-vision gaps: inflammation of the retina and optic nerve can create small blind spots.

11. Episodes of better and worse: symptoms can flare and then improve, and this up-and-down pattern can repeat.

12. Headache or brow ache: ciliary spasm and elevated pressure can cause frontal discomfort.

13. Dry, gritty feeling: the tear gland or surface can be involved, giving a dry-eye sensation.

14. Systemic clues: cough, shortness of breath, skin bumps, swollen joints, or fatigue can ride along and point toward sarcoidosis as the cause of the eye problem. PMC

15. Facial swelling or facial weakness with fever: a special sarcoid subtype called Heerfordt-Waldenström syndrome adds parotid swelling, uveitis, fever, and sometimes facial nerve palsy. EyeWikiPMC

Diagnostic tests

Doctors mix what they see in the eye with blood tests, imaging, and sometimes biopsy to confirm sarcoid uveitis and to rule out other causes like tuberculosis and syphilis that can look very similar in the eye.

A) Physical exam

1. Whole-body check for sarcoid clues: doctors look and feel for enlarged lymph nodes, skin bumps, tender joints, and breathing signs, because eye inflammation plus body clues points strongly toward sarcoidosis. PMC

2. Parotid and lacrimal gland exam: felt or visible swelling near the ears and in the tear glands supports sarcoid involvement and fits Heerfordt syndrome when paired with uveitis and fever. EyeWiki

3. Skin inspection for biopsy targets: small skin nodules or scars that turn bumpy are good spots to sample because they may show the characteristic non-caseating granulomas. PMC

4. Chest and respiratory check: crackles are uncommon but breathing symptoms push doctors toward chest imaging to look for the classic bilateral hilar lymph nodes. ATS Journals

B) Manual eye tests

5. Best-corrected visual acuity and pinhole: measures how much the inflammation is blurring vision and tracks recovery over time.

6. Slit-lamp exam of the front of the eye: looks for mutton-fat keratic precipitates, iris nodules, and posterior synechiae, which are hallmark sarcoid signs. EyeWiki

7. Applanation tonometry (eye pressure): checks for high pressure from trabecular inflammation or steroid response, because untreated pressure spikes can damage the optic nerve. MDPI

8. Dilated fundus exam (indirect ophthalmoscopy): looks for vitreous snowballs/strings, periphlebitis, candle-wax drippings, optic disc leakage, and choroidal granulomas. Review of OptometryEyeWiki

C) Laboratory and pathological tests

9. Serum ACE (angiotensin-converting enzyme): often higher in active sarcoidosis because granuloma cells make ACE; it is supportive, not definitive. PMC

10. Serum sIL-2R (soluble interleukin-2 receptor): a marker of T-cell activation that can be more sensitive than ACE in some series and helps when biopsy is not yet available. PMCBioMed Central

11. Serum lysozyme: another granuloma-related marker that can rise in sarcoidosis and adds weight to the overall picture when combined with other tests. MDPI

12. Calcium studies: blood and 24-hour urine calcium can be elevated because granulomas make extra active vitamin D; this helps support systemic sarcoidosis. PMC

13. Tests to rule out mimics (IGRA/TB skin test, syphilis serology): QuantiFERON-TB and treponemal tests are used because TB and syphilis can mimic sarcoid uveitis; note that a positive TB blood test can occur in a minority of sarcoid uveitis patients and does not exclude sarcoidosis in low-TB settings, so doctors interpret it with the whole clinical picture. PubMed

14. Tissue biopsy for non-caseating granulomas: a small sample from a conjunctival bump, skin lesion, lacrimal gland, or lymph node showing non-caseating granulomas is the gold standard confirmation when accessible and safe. NCBI

D) Electrodiagnostic tests

15. Electroretinography (ERG): measures how well the retina’s photoreceptors and inner layers are working, which helps if inflammation or treatment has affected retinal function. NCBI

16. Visual evoked potentials (VEP): checks the signal from the eye to the brain and helps when optic nerve inflammation is suspected. NCBI

E) Imaging tests

17. Optical coherence tomography (OCT): a painless scan that shows cystoid macular edema, subretinal fluid, or choroidal thickening in great detail and helps monitor recovery. PMC

18. Fluorescein angiography (FA): highlights retinal vessel leakage, disc leakage, capillary non-perfusion, and macular edema; this is a classic tool for posterior sarcoid uveitis. PMC

19. Indocyanine green angiography (ICG): looks deeper at the choroid and can reveal hypocyanescent choroidal granulomas not obvious on FA, which helps confirm and map disease. SpringerOpenEyeWiki

20. Chest imaging (CXR/HRCT ± EBUS-guided node sampling): chest X-ray or CT often shows bilateral hilar lymphadenopathy that supports the diagnosis, and modern guidelines favor endobronchial ultrasound (EBUS) to sample lymph nodes when tissue proof is needed. FDG-PET/CT can help find hidden sites for biopsy in complex cases. ATS JournalsMedscapePMC

Mechanism: Cold causes vasoconstriction and temporarily reduces superficial inflammatory signals.

6) Eyelid hygiene if crusting/meibomian issues
Description: Gentle lid cleaning; warm compress if meibomian glands are clogged.
Purpose: Keep the tear film stable and reduce surface inflammation that can aggravate discomfort.
Mechanism: Removes debris and normalizes oil flow to the tear film.

7) Avoid contact lenses during flares
Description: Switch to glasses until the eye is quiet.
Purpose: Lower irritation and infection risk while the eye is inflamed or on steroids.
Mechanism: Eliminates a mechanical stressor and reduces biofilm risk on the eye surface.

8) Don’t rub the eyes
Description: Use a clean tissue or lubricating drop instead.
Purpose: Prevent extra inflammation, keratoconus risk, and pressure spikes.
Mechanism: Avoids mechanical histamine release and pressure surges.

9) Sleep & stress care
Description: Aim for regular, adequate sleep and use simple stress tools (breathing, short walks).
Purpose: Support immune balance and pain tolerance.
Mechanism: Sleep loss and stress can amplify inflammatory pathways; steady routines help calm them.

10) Exercise most days
Description: Moderate activity (e.g., brisk walking) unless your doctor advises otherwise.
Purpose: Improve overall function, mood, and cardio-respiratory health that sarcoidosis can affect.
Mechanism: Exercise lowers systemic inflammatory markers and supports steroid weaning.

11) Anti-inflammatory eating pattern
Description: Base meals on vegetables, fruits, legumes, whole grains, fish, nuts, seeds; limit ultra-processed foods, added sugar, and excess salt.
Purpose: Support metabolic health during steroids; reduce body-wide inflammatory tone.
Mechanism: Fiber, omega-3 fats, polyphenols, and micronutrients help regulate cytokines and oxidative stress. Stop Sarcoidosis+1Cleveland Clinic

12) Sunlight & calcium/vitamin D caution specific to sarcoidosis
Description: Do not start calcium or vitamin D on your own; avoid excessive sun if you’ve had high calcium.
Purpose: Prevent hypercalcemia and kidney stones, which are more likely in sarcoidosis.
Mechanism: Sarcoid granulomas can activate vitamin D outside the kidneys, raising calcium; sunlight and supplements can worsen this. Discuss any plan with your doctor. AAFPPMCSarcoidosisUK

13) Hydration
Description: Drink water regularly, more in heat.
Purpose: Support kidneys if calcium runs high or if you’re on diuretics/acetazolamide for macular edema.
Mechanism: Maintains urine flow and lowers stone risk when hypercalciuria is present. AAFP

Drug treatments

Doses below are typical clinical ranges used by specialists for non-infectious uveitis; your dosing and tapering should always be individualized.

1) Prednisolone acetate 1% eye drops (topical corticosteroid)
Dose/Time: Often every 1–2 hours while awake at the start (severe anterior uveitis), then taper over weeks per response.
Purpose: Rapidly quiet front-of-eye inflammation, relieve pain/light sensitivity, prevent synechiae.
Mechanism: Steroid blocks multiple inflammatory signals (NF-κB, cytokines).
Side effects: Eye-pressure rise, delayed healing, cataract with prolonged use—so pressure is monitored. EyeWiki

2) Cycloplegic/mydriatic drops (e.g., atropine 1% BID or cyclopentolate 1% TID)
Class: Anticholinergic.
Purpose: Relax the ciliary muscle to ease pain and keep the pupil moving to prevent “sticking” (posterior synechiae).
Mechanism: Temporarily paralyzes accommodation and dilates the pupil.
Side effects: Blurry near vision, light sensitivity; rare systemic anticholinergic effects. EyeWiki

3) Periocular steroid injection (posterior sub-Tenon triamcinolone 40 mg)
Class: Local corticosteroid depot.
Purpose: Treat intermediate/posterior inflammation or macular edema when drops are not enough.
Mechanism: Slow steroid release near the back of the eye.
Side effects: Eye-pressure rise, cataract; very small risk of infection/ptosis—so monitored by a uveitis/retina specialist. EyeWiki

4) Intravitreal dexamethasone implant 0.7 mg (Ozurdex®)
Class: Long-acting intraocular steroid implant.
Purpose: Control non-infectious posterior uveitis and uveitic macular edema for ~3–4 months.
Mechanism: Controlled steroid delivery inside the eye reduces retinal and choroidal inflammation.
Side effects: Eye-pressure spikes, cataract progression; requires pressure checks. PubMed

5) Intravitreal fluocinolone acetonide implant 0.18–0.19 mg (Yutiq®/Iluvien®)
Class: Very long-acting intraocular steroid implant.
Purpose: Maintain control of chronic, recurrent non-infectious posterior uveitis for up to ~3 years.
Mechanism: Ultra-low-dose continuous steroid release.
Side effects: High likelihood of cataract and possible pressure rise—chosen for eyes needing durable control. EyeWiki

6) Oral prednisone (systemic corticosteroid)
Dose/Time: Common start around 0.5–1 mg/kg/day, then taper per response (often over weeks).
Purpose: Calm moderate–severe inflammation or bilateral/posterior disease, and bridge to steroid-sparing therapy.
Mechanism: Global anti-inflammatory and immunosuppressive effects.
Side effects: Elevated blood sugar/pressure, mood changes, weight gain, bone loss, infection risk—hence the push to add steroid-sparing agents. PMC

7) Methotrexate (steroid-sparing immunomodulator)
Class: Antimetabolite (folate antagonist), weekly dosing.
Dose/Time: Often 10–25 mg once weekly orally or subcutaneously; folic acid added; response in 6–12 weeks.
Purpose: Long-term control and steroid reduction.
Mechanism: Dampens T-cell activity and cytokine production.
Side effects: Liver enzyme rise, cytopenias, mouth sores; avoid in pregnancy; routine labs required. FDA Access Data

8) Mycophenolate mofetil (steroid-sparing)
Class: Antimetabolite (IMP-DH inhibitor).

Purpose: Maintain remission and allow prednisone taper.
Mechanism: Selectively reduces lymphocyte proliferation.
Side effects: GI upset, cytopenias, infection risk; contraception needed due to teratogenicity. Ani Pharmaceuticals Investor Portal

9) Azathioprine (steroid-sparing)
Class: Purine analogue.
Dose/Time: Often 1–2 mg/kg/day; effect in 6–12 weeks.
Purpose: Alternative when methotrexate or mycophenolate are not suitable.
Mechanism: Inhibits DNA synthesis in rapidly dividing immune cells.
Side effects: Bone-marrow suppression, liver toxicity; TPMT testing may guide safety. PubMed

10) Adalimumab (biologic anti-TNF-α)
Class: Monoclonal antibody.
Dose/Time: Typical 40 mg subcutaneous every 2 weeks (adult NIU regimen; loading strategies vary by protocol).
Purpose: For non-infectious uveitis that is vision-threatening, relapsing, or steroid-dependent despite antimetabolites.
Mechanism: Blocks TNF-α, a master inflammatory cytokine in uveitis.
Side effects & screening: Infection risk (TB, hepatitis B reactivation), injection-site reactions; TB/viral screening is recommended before starting anti-TNF therapy. ScienceDirectEyeWikiBMJ

Bonus—targeted add-on for macular edema: Acetazolamide (oral carbonic anhydrase inhibitor, e.g., 250 mg BID–QID short courses) can help stubborn uveitic cystoid macular edema by improving fluid pumping across the retinal pigment epithelium; results vary, and monitoring is needed. ScienceDirectPMC

Dietary “molecular” supplements

Evidence for supplements in sarcoid uveitis is limited; these are general anti-inflammatory or ocular-supportive ideas. Avoid any supplement that conflicts with your labs (especially vitamin D or calcium in sarcoidosis—see below). Always review with your physician.

1. Omega-3 (EPA+DHA) — ~1–2 g/day EPA+DHA.
   Function: systemic anti-inflammatory support; may aid dry-eye comfort.
   Mechanism: shifts eicosanoids toward less-inflammatory mediators.

2. Curcumin (with piperine) — ~500–1000 mg/day standardized curcumin.
   Function: broad cytokine dampening.
   Mechanism: NF-κB and COX-2 modulation.

3. Green tea extract (EGCG) — ~150–300 mg/day EGCG.
   Function: antioxidant support.
   Mechanism: polyphenol-driven reduction of oxidative stress.

4. Resveratrol — ~100–250 mg/day.
   Function: antioxidant and SIRT-related signaling effects.
   Mechanism: reduces oxidative and inflammatory signaling cascades.

5. Quercetin — ~500 mg/day.
   Function: mast-cell stabilization and antioxidant effects.
   Mechanism: inhibits histamine release and pro-inflammatory enzymes.

6. Lutein + zeaxanthin — ~10–20 mg lutein + 2–4 mg zeaxanthin/day.
   Function: macular pigment support; helps retinal antioxidant capacity.
   Mechanism: blue-light filtering and free-radical scavenging in the macula.

7. Vitamin C — ~250–500 mg/day (diet first).
   Function: collagen and antioxidant support.
   Mechanism: regenerates other antioxidants and supports wound healing.

8. Vitamin E (mixed tocopherols) — ~100–200 IU/day.
   Function: lipid antioxidant for cell membranes (retina is lipid-rich).
   Mechanism: limits peroxidation.

9. Probiotics (multistrain) — as labeled.
   Function: gut–immune crosstalk support; can help GI tolerance when on systemic meds.
   Mechanism: modulates gut cytokine signaling.

10. Magnesium (glycinate/citrate) — ~200–400 mg elemental/day.
    Function: supports muscle relaxation (helps ciliary spasm discomfort) and metabolic balance.
    Mechanism: modulates NMDA and inflammatory pathways.

Important sarcoidosis caveat: Avoid self-starting vitamin D or calcium; discuss any plan with your clinician because sarcoidosis can cause vitamin D over-activation and high calcium. AAFPPMC

Regenerative / stem-cell drugs

In autoimmune uveitis, “boosting” the immune system is not the goal—over-activity is the problem. We safely modulate the immune response. There are no approved stem-cell drugs for sarcoid uveitis as of today. Some advanced options are used off-label by specialists when standard care is not enough:

1. Adalimumab (anti-TNF-α) — 40 mg SC every 2 weeks.
   Function: strong immunomodulation to maintain remission; steroid-sparing.
   Mechanism: neutralizes TNF-α. (Screen for TB/hepatitis first.) ScienceDirectEyeWiki

2. Infliximab (anti-TNF-α) — ~5 mg/kg IV at weeks 0, 2, 6, then q6–8w.
   Function: biologic rescue in severe, vision-threatening uveitis.
   Mechanism: monoclonal antibody to TNF-α; rapid cytokine suppression. (TB/hepatitis screening applies.) ScienceDirect

3. Tocilizumab (anti-IL-6 receptor) — IV 8 mg/kg q4w or SC 162 mg weekly; specialist decides.
   Function: useful for refractory uveitic macular edema and cases that fail anti-TNF.
   Mechanism: blocks IL-6 signaling to reduce edema and inflammation.
   Evidence suggests IV can sometimes resolve macular edema faster than SC in refractory cases. PubMedAmerican Academy of Ophthalmology

4. Rituximab (anti-CD20 B-cell therapy, off-label) — Common rheumatology regimen: 1000 mg IV day 1 & 15; cycles per response.
   Function: for select, refractory non-infectious uveitis phenotypes when conventional and anti-TNF agents fail or are contraindicated.
   Mechanism: depletes CD20-positive B cells. SpringerOpenPMC

5. Intravitreal fluocinolone/dexamethasone implants — see above doses.
   Function: long-acting local immunosuppression (steroid) for chronic posterior disease.
   Mechanism: sustained steroid release inside the eye to control immune activity. EyeWikiPubMed

6. Mesenchymal stem-cell (MSC) therapy (investigational) — no approved dose/regimen for sarcoid uveitis.
   Function: experimental immune-modulating and “tissue-healing” approach studied in small series for autoimmune uveitis; not standard of care.
   Mechanism: proposed paracrine immune regulation; uncertain efficacy/safety profiles in eye disease. Discuss only in research settings with ethics approval. PMC

Surgeries — procedures

1) Cataract surgery (phacoemulsification with lens implant)
Why: Cataract often develops from inflammation or steroid use; when vision is reduced and the eye is quiet, surgery restores clarity.
Key principle: Most authorities advise the uveitis be in strict remission for ~3 months before elective cataract surgery to lower the risk of post-op inflammation and macular edema; peri-operative anti-inflammatory cover is planned by your specialist. American Academy of OphthalmologyPMC

2) Glaucoma surgery (trabeculectomy or tube shunt/GDD)
Why: If uveitis or steroids cause high eye pressure that medicines and lasers cannot control, surgery protects the optic nerve.
Notes: Both approaches can work; success and side-effect profiles differ, and control of inflammation strongly influences outcomes. MDPIPubMed

3) Pars plana vitrectomy (PPV)
Why: For dense vitreous debris, non-clearing vitreous hemorrhage, traction, or to obtain samples when the diagnosis is unclear; PPV can also help reduce inflammatory load and improve vision in selected cases. PMCMDPI

4) Retinal laser (e.g., panretinal photocoagulation) in ischemic vasculitis
Why: If sarcoid retinal vasculitis leads to ischemia and abnormal vessel growth, targeted laser may reduce bleeding risk and stabilize the retina (used selectively by retina specialists).

5) Combined procedures
Why: In complex cases, surgeons may combine cataract surgery with vitrectomy or perform glaucoma surgery separately depending on urgency and inflammation control, with close peri-operative steroid planning. EyeWiki

Preventions

1. Never self-start vitamin D or calcium; in sarcoidosis this can cause high calcium—ask your doctor first. AAFP

2. Protect from excessive sun if you’ve had high calcium or active sarcoidosis; follow your clinician’s advice. Patient Priorities

3. Quit smoking and avoid fumes/dust. Cleveland Clinic

4. Keep vaccines current before strong immunosuppression (no live vaccines while immunosuppressed).

5. TB and hepatitis B screening before anti-TNF biologics; treat latent infections first. BMJAmerican Academy of Ophthalmology

6. Adhere to eye drops and tapers to prevent rebound inflammation.

7. Regular eye-pressure checks—especially on steroids or after steroid implants. EyeWiki

8. Healthy, anti-inflammatory diet and weight-bearing exercise to counter steroid effects (with vitamin D/calcium handled carefully). Stop SarcoidosisBioMed Central

9. Prompt care for new symptoms (pain, photophobia, floaters, blurred vision, halos).

10. Keep systemic sarcoidosis under control with your pulmonary/rheumatology team; eye health improves when the whole body is stable.

---

When to see a doctor urgently

• New or worsening eye pain, light sensitivity, redness, blurred vision, or floaters;

• Halos or headache with nausea/vomiting (possible pressure spike);

• Any sudden vision drop or flashes/curtain (retina warning);

• Side effects from treatment: mood swings, severe insomnia, high blood sugar or blood pressure, swelling of legs, repeated infections, shortness of breath;

• Signs of high calcium (excessive thirst/urination, abdominal pain, confusion) if you have sarcoidosis;

• Before you start or stop any supplement (especially vitamin D/calcium) or biologic.

Foods to favor—and to limit/avoid

Eat more of (daily foundation):

1. Leafy greens & colorful vegetables (spinach, kale, peppers, berries) for antioxidants and fiber.

2. Legumes & whole grains (lentils, beans, oats, brown rice) for steady energy and gut health.

3. Fish (especially oily fish like salmon/sardines) 2–3×/week for omega-3s.

4. Nuts & seeds (walnuts, chia, flax) in modest portions for healthy fats.

5. Olive oil as main cooking fat.

6. Citrus and vitamin-C-rich fruits (oranges, kiwi) for antioxidant support.

7. Herbs/spices (turmeric with pepper, ginger, garlic) for natural polyphenols.

8. Yogurt/kefir or probiotics if tolerated, to support gut balance.

9. Plenty of water daily.

10. Protein from lean sources (fish, poultry, tofu, beans) to preserve muscle on steroids. Stop Sarcoidosis+1

Limit or avoid (especially during active disease or steroid use):

1. Ultra-processed foods and fast food high in refined oils/salt/sugar.

2. Sugary drinks and sweets—worsen steroid-related blood sugar spikes.

3. Excess salt—worsens fluid retention and blood pressure on steroids.

4. Excess alcohol—adds inflammation and interacts with meds.

5. High-dose vitamin D or calcium supplements unless your clinician prescribes them.

6. Very high-calcium diets if your calcium is elevated (follow individualized medical advice). AAFP

7. Large amounts of red/processed meats—pro-inflammatory pattern.

8. Trans fats and industrial seed-oil heavy snacks—increase inflammation. Cleveland Clinic

9. Energy drinks or excess caffeine—can worsen sleep and eye strain.

10. Any supplement not cleared by your doctor (especially with biologics or liver-acting drugs).

Frequently asked questions

1) Is sarcoid uveitis contagious?
No. It is an immune condition, not an infection that spreads between people.

2) What causes it?
The exact trigger is unknown. The immune system forms granulomas in genetically susceptible people. When these form in the uvea, you get uveitis.

3) Will I lose vision?
Most people do well when inflammation is treated early and monitored closely. The biggest threats are untreated inflammation, macular edema, and glaucoma—so follow-up is key. NCBI

4) Why are steroids used so much?
They are the fastest way to quiet inflammation. Because long-term steroids have side effects, doctors add steroid-sparing medications when needed. MDPI

5) What is a steroid-sparing drug?
Medicines like methotrexate, mycophenolate, or azathioprine that control inflammation so your steroid dose can be reduced. They take weeks to work and require lab monitoring. FDA Access DataAni Pharmaceuticals Investor Portal

6) What are biologics?
Targeted antibodies such as adalimumab or infliximab that block specific inflammatory signals. They’re used when disease is severe or keeps returning. Screening for TB and hepatitis B is recommended before starting them. ScienceDirectBMJ

7) Why check eye pressure so often?
Steroids (drops, injections, or implants) can raise eye pressure and lead to glaucoma; early detection prevents nerve damage. EyeWiki

8) How long will I need treatment?
Uveitis can be acute or chronic. Many people need months to years of tailored therapy, with careful tapers and at-home flare plans directed by their specialist.

9) Are there special concerns with vitamin D and calcium?
Yes. Sarcoidosis can over-activate vitamin D, which can raise blood calcium. Do not start vitamin D or calcium without your clinician’s advice. AAFP

10) Can diet really help my eyes?
Diet doesn’t replace medicine, but an anti-inflammatory pattern supports overall health and may help you tolerate treatment better—especially while on steroids. Stop Sarcoidosis+1

11) I have macular edema—what helps besides steroids?
Your team may add acetazolamide tablets or consider steroid implants or biologics depending on your case. ScienceDirect

12) Is cataract surgery safe if I have uveitis?
Yes—when timed correctly. Most experts want the eye quiet for ~3 months and will plan strong anti-inflammatory cover around surgery. American Academy of Ophthalmology

13) What about pregnancy?
Plan ahead with your obstetrician and uveitis specialist. Some medicines are unsafe in pregnancy (e.g., methotrexate, mycophenolate). Others may be used with caution.

14) Can I wear contacts?
Not during flares. Many can return to contacts once the eye is calm and your doctor agrees.

15) How do doctors decide between methotrexate, mycophenolate, azathioprine, or biologics?
They consider disease location/severity, your other health conditions, pregnancy plans, lab results, and how you responded to past treatments—always aiming to control inflammation with the lowest risk overall. FDA Access DataAni Pharmaceuticals Investor Portal
