Birdshot Retinochoroiditis

Birdshot retinochoroiditis is a rare, long-lasting eye inflammation. It affects the back of the eye (the retina and the choroid). Doctors see many small, creamy, pale spots in both eyes. These spots are usually around the optic nerve and arc outwards like a shot pattern from a shotgun. The disease is a type of posterior uveitis. It can slowly damage vision if it is not found and treated. Most patients are adults, often in mid-life. The condition is very strongly linked to a tissue-type marker called HLA-A29. But the exact trigger is still unknown. Researchers think it is an autoimmune disease, where the immune system attacks the eye by mistake. PMC+3AAO+3EyeWiki+3

Birdshot retinochoroiditis is a rare, long-lasting, usually both-eyes inflammation at the back of the eye (posterior uveitis). Doctors see many creamy, oval spots in the deeper eye layer (choroid) and the retina. It is strongly linked to the genetic marker HLA-A29. People often notice night-vision trouble, glare, flashes, or floaters; vision can slowly worsen without treatment. This condition is non-infectious and needs careful, long-term follow-up to protect sight. NCBI+2EyeWiki+2

Scientists think the immune system attacks the eye in people who carry HLA-A29, which makes them more likely to get birdshot. T-cells and inflammatory chemicals drive the swelling in the retina and choroid, causing the typical cream-colored “bird-shot” spots and sometimes swelling at the macula that blurs vision. Because it is non-infectious, therapy focuses on calming the immune response and controlling inflammation safely over time. PMC+1

Other names

Doctors may use several names for the same disease. These include birdshot chorioretinopathy, birdshot uveitis, HLA-A29 uveitis, and vitiliginous choroiditis. All point to the same condition and stress either the white “birdshot” lesions, the location (retina + choroid), or the strong HLA-A29 link. Wikipedia+1

Types

There is no official set of “subtypes,” but clinicians think about birdshot in a few useful ways:

1. Early vs. established disease. In early disease, the white lesions may be subtle and ERG or visual field tests can pick up function loss before vision drops. Later, the lesions are more obvious and vision problems are clearer. PMC+1

2. Active (inflamed) vs. quiet (inactive). Active disease shows more inflammation on exam and imaging and often worse ERG or field results. Quiet disease shows fewer signs of inflammation but may still have permanent damage. PMC

3. Predominant retina involvement vs. choroid involvement. Some patients show more retinal dysfunction (ERG changes, reduced sensitivity). Others show more choroidal lesions visible on indocyanine green angiography (ICGA). Most have a mix, and multimodal imaging helps. BioMed Central+1

4. HLA-A29-positive vs. rare HLA-A29-negative, birdshot-like cases. HLA-A29 is present in the vast majority. HLA-A29-negative “birdshot-like” pictures are uncommon and may represent look-alikes rather than true birdshot. ltd.aruplab.com+1

Causes

The exact cause is not proven. But research points to autoimmunity with strong genetic risk plus unknown triggers. Each item below is a proposed cause or contributor. Some are well supported (like HLA-A29). Others are still theories. I note that clearly.

1. Autoimmune reaction. The immune system targets eye tissues by mistake, leading to chronic inflammation. This is the main idea behind the disease. NCBI

2. HLA-A29 genetic marker. Overwhelmingly common in birdshot and gives very high relative risk. Its absence makes the diagnosis much less likely. PMC+1

3. ERAP1/ERAP2 gene interactions. These genes shape which peptides are shown to immune cells. Certain variants with HLA-A29 may promote the abnormal immune response. (Active research; strong association.) Frontiers

4. T-cell–driven immunity. HLA-A29 presents peptides to T-cells; mis-presentation may activate harmful T-cells in the eye. (Mechanistic model.) PMC

5. Molecular mimicry (hypothesis). A past infection might show similar peptides, “training” T-cells that later attack the eye. (Theory, not proven.) PMC

6. Environmental trigger (unknown). Some outside factor may start or flare the disease in genetically at-risk people. (Theory.) PMC

7. Breakdown of immune privilege in the eye. Eye tissues are usually protected from aggressive immune attacks; when that balance fails, inflammation can persist. (Concept from uveitis science.) PMC

8. Choroidal antigen exposure. Damage may expose hidden eye antigens to the immune system, feeding a loop of inflammation. (Hypothesis.) PMC

9. Caucasian ancestry risk pattern. Birdshot is much more common in people of Western European ancestry, matching HLA-A29 distribution. (Epidemiology observation.) PMC+1

10. Middle-age onset biology. Onset often in the 40s–60s suggests age-related immune shifts may matter. (Observation.) PMC

11. Family aggregation (rare reports). Very uncommon familial clustering hints at shared genes beyond HLA-A29, but data are limited. (Anecdotal.) PMC

12. Abnormal peptide trimming (ERAP). Specific ERAP variants change peptide length and content for HLA-A29, possibly favoring harmful antigens. (Mechanistic link.) Frontiers

13. Cytokine imbalance. Chronic uveitis often involves raised inflammatory cytokines that sustain tissue damage. (General uveitis concept applied to birdshot.) PMC

14. Breaks in outer blood-retina barrier. Choroidal/retinal inflammation may worsen when this barrier is leaky. (Concept.) PMC

15. Antigen presentation by local eye cells. Retinal pigment epithelium and resident immune cells may present antigens and amplify disease. (Concept.) PMC

16. Low infectious burden as a direct cause—unlikely. No single germ explains birdshot. Workups usually do not find a specific infection. (Important negative.) PMC

17. HLA-A29 is a risk, not destiny. Many HLA-A29-positive people never get birdshot, so extra factors must be needed. MDPI

18. Gene–environment interplay. HLA-A29 + ERAP + unknown triggers likely all play a role together. (Consensus model.) Frontiers

19. Systemic autoimmune tendency (possible). Some patients have other autoimmune issues, suggesting shared immune wiring. (Association reports, not universal.) EyeWiki

20. Individual immune history. Prior immune events (e.g., infections, vaccines, stressors) may shape T-cell memory; in a small subset, this could tilt toward birdshot in the HLA-A29 background. (Hypothesis consistent with autoimmune models.) PMC

Symptoms

Symptoms can be mild at first. Many people notice vision problems in both eyes. Common patterns are below.

1. Blurred or dim vision. Vision may slowly get worse over months or years, especially without treatment. GARD Information Center+1

2. Floaters. Small spots that seem to drift across vision due to cells or debris in the vitreous from inflammation. GARD Information Center+1

3. Poor night vision (nyctalopia). Seeing in low light becomes hard. This is very typical. EyeWiki

4. Color vision changes (dyschromatopsia). Colors seem washed out or “not right.” EyeWiki

5. Photopsias (flashes) or glare. Brightness and glare bother the eyes; flashing lights may appear. EyeWiki

6. Loss of contrast. Fine details are harder to see even when letters on the chart still look OK. (Functional testing often shows this early.) PMC

7. Visual field defects. Patches of missing vision, often in the mid-periphery; ERG and perimetry help track this. PMC

8. Metamorphopsia. Straight lines may look bent if the macula is affected. (Not in every case.) PMC

9. Light sensitivity (photophobia). Inflammation makes bright light uncomfortable. PMC

10. Reading difficulty. Small print becomes hard due to reduced contrast, color changes, or macular swelling. PMC

11. Slow vision recovery after bright light. Adapting back to normal may take longer. (Functional symptom.) PMC

12. Poor depth perception. Changes in contrast and macular function can affect stereo vision. PMC

13. Headache is not typical. Pain is usually minimal because posterior uveitis is deeper; this helps separate it from some front-of-the-eye problems. Cleveland Clinic

14. Vision fluctuates. Symptoms can wax and wane with disease activity or treatment changes. PMC

15. Later-stage permanent loss. Without control, damage can cause lasting vision loss. Early diagnosis and follow-up lower this risk. Cleveland Clinic

Diagnostic tests

A) Physical exam (at the slit lamp and dilated exam)

1. Best-corrected visual acuity. Basic measure of how well you see letters. It tracks overall function and treatment response over time. PMC

2. Pupil exam. Checks for relative afferent pupillary defect and symmetry; severe or asymmetric retinal damage can affect the pupillary response. PMC

3. Anterior segment exam. Rules out or notes front-of-eye inflammation (cells/flare). Birdshot mainly hits the back, but mild cells can appear. PMC

4. Dilated fundus exam. The key step: the doctor looks for the classic, cream-colored “birdshot” lesions arrayed around the optic nerve and along the vessels in both eyes. AAO

B) Manual/bedside functional tests

5. Color vision testing (plates). Detects subtle color loss common in birdshot. Simple, fast, and repeatable. EyeWiki

6. Amsler grid. A handheld square grid helps detect waviness or missing spots near the center of vision (macular signs). PMC

7. Confrontation visual fields. Quick side-by-side test for large field defects; more detailed automated perimetry follows if needed. PMC

C) Laboratory and pathological tests

8. HLA-A29 typing (genetic marker). Very high association (about 80–98% positive). A positive result supports the diagnosis; a negative result lowers the odds a lot but does not fully exclude all look-alikes. ltd.aruplab.com+1

9. Baseline inflammatory labs (e.g., ESR/CRP). Non-specific markers of inflammation; help rule out infections and other uveitis causes. PMC

10. Targeted rule-out tests. Depending on history, clinicians may order tests to exclude syphilis, TB, sarcoidosis, or Lyme, since these can mimic posterior uveitis. (Birdshot itself does not have a specific blood test beyond HLA-A29.) PMC

D) Electrodiagnostic tests (measure retinal function)

11. Full-field electroretinogram (ERG). A core test in birdshot. Delayed and reduced 30-Hz cone flicker responses are especially sensitive and often change before vision drops. ERG is also excellent for monitoring treatment over time. PMC+2BioMed Central+2

12. Multifocal ERG (mfERG). Maps retinal function across different regions and can pick up local dysfunction that matches field loss or OCT changes. BioMed Central

E) Imaging tests (structure and circulation)

13. Optical coherence tomography (OCT). High-resolution cross-sections of the macula and retina. Finds macular edema, outer retinal damage, and atrophy; tracks swelling and treatment response. PMC

14. OCT angiography (OCT-A). Non-dye blood-flow maps; may show choriocapillaris and retinal plexus changes in some patients. It supplements dye tests. PMC

15. Fundus autofluorescence (FAF). Highlights stress or loss of the retinal pigment epithelium; helpful for mapping the footprint of disease. PMC

16. Fluorescein angiography (FA). A dye test that shows retinal vessel leakage, optic disc leakage, and macular edema—signs of activity. PMC

17. Indocyanine green angiography (ICGA). Very useful to see choroidal lesions and hypofluorescent spots that match the “birdshot” pattern, sometimes more sensitively than the clinical exam. ajo.com

18. Widefield photography. Documents lesion number, shape, and distribution for follow-up. PMC

19. Automated perimetry (formal visual field). Quantifies field loss pattern and monitors improvement or worsening. Often correlates with ERG findings. ScienceDirect

20. B-scan ultrasonography (selected cases). Rarely needed; helps if media are hazy to assess posterior segment or rule out other diagnoses. PMC

Dietary molecular supplements (supportive, not cures)

Use only under clinician guidance, especially with immunosuppression. Evidence focuses on general ocular/systemic support rather than birdshot-specific cures.

1. Omega-3 fatty acids (ALA/EPA/DHA).
   Can support general inflammatory balance and cardiovascular health during long therapies. They do not replace medical treatment but may help comfort in some patients. Discuss bleeding risk if combined with anticoagulants. Mayo Clinic

2. Vitamin D (with calcium as needed).
   Helpful for bone support in patients who need systemic steroids; check levels and avoid excess. Not a birdshot cure; part of whole-body support plan. National Eye Institute

3. Lutein/zeaxanthin.
   Macular carotenoids may support retinal antioxidant capacity; adjunct only. Balance with diet rich in leafy greens. Mayo Clinic

4. Vitamin B-complex/folate (with methotrexate).
   Folic acid is standard with methotrexate to reduce side effects; dosing individualized by prescriber. FDA Access Data

5. Probiotics (general wellness).
   May support GI tolerance if on immunosuppressants, but check safety with your clinician; not disease-specific therapy. Mayo Clinic

6. Magnesium (sleep/muscle comfort support).
   May help sleep or cramps in some individuals; ensure no kidney issues and avoid excess. Mayo Clinic

7. Antioxidant-rich diet pattern.
   Emphasize foods (berries, greens, legumes) over pills; food-first approach supports overall health during treatment. Mayo Clinic

8. Curcumin/turmeric (caution).
   Has anti-inflammatory signals in general research, but interactions (anticoagulants) and quality vary; discuss first. Mayo Clinic

9. CoQ10 (energy support).
   Sometimes used for general fatigue; limited eye-specific evidence. Avoid if interacting drugs or bleeding risk. Mayo Clinic

10. Zinc (within RDA).
    Essential trace mineral; excess can harm copper balance—use only if deficient and under guidance. Mayo Clinic

Drugs for “immunity booster / regenerative / stem-cell

There are no FDA-approved “immunity boosters” or stem-cell drugs for birdshot. Below are clinician-directed therapies that modulate the immune system; they are not “boosters.” Use only under specialist care.

1. Adalimumab (immune modulation).
   Biologic that down-regulates pathologic inflammation in non-infectious uveitis; improves control and preserves vision; infection screening essential. FDA Access Data

2. Infliximab (immune modulation).
   IV TNF-α blocker for refractory cases; powerful effect requires close monitoring for infections and infusion reactions. FDA Access Data

3. Methotrexate (immune modulation).
   Weekly antimetabolite that lowers lymphocyte-driven inflammation; strict lab checks and folate support reduce toxicity risk. FDA Access Data

4. Mycophenolate mofetil (immune modulation).
   Purine-pathway blocker that reduces T/B-cell proliferation; helpful as steroid-sparing maintenance in chronic NIU. FDA Access Data

5. Cyclosporine (immune modulation).
   Calcineurin inhibitor that blocks T-cell activation; requires blood-pressure and kidney monitoring. FDA Access Data

6. Local steroid implants (tissue-targeted “regenerative support”).
   Not true stem-cell therapy, but by keeping inflammation quiet (Retisert, Yutiq, Ozurdex), retinal tissue gets a chance to recover function where possible. FDA Access Data+2FDA Access Data+2

Surgeries/procedures

1. Fluocinolone acetonide implant (Retisert).
   Procedure. Surgical placement through the sclera into the posterior segment. Why. For chronic posterior NIU needing durable local control when systemic drugs are unsuitable. Notes. High rates of cataract and glaucoma need proactive management. FDA Access Data

2. Fluocinolone acetonide micro-insert (Yutiq).
   Procedure. In-office intravitreal injection of a tiny non-bioerodible insert. Why. Long-term, lower-dose local steroid with simpler placement than Retisert. Notes. Monitor IOP and lens status. FDA Access Data

3. Dexamethasone implant (Ozurdex).
   Procedure. In-office intravitreal delivery of a biodegradable rod. Why. Time-limited steroid effect for NIU or macular edema, repeatable per response. Notes. IOP/cataract monitoring and infection precautions are essential. FDA Access Data

4. Suprachoroidal triamcinolone (Xipere).
   Procedure. Office-based injection into the suprachoroidal space. Why. Treat uveitic macular edema with compartment-targeted steroid delivery. Notes. Special needle system; follow label steps and post-injection checks. FDA Access Data

5. Cataract/glaucoma surgery (as needed).
   Procedure. Standard phacoemulsification or glaucoma procedures if steroid response or disease damage leads to lens opacity or high pressure. Why. Restore clarity and control pressure to protect the optic nerve. Notes. Time surgery when inflammation is controlled. National Eye Institute

Preventions (practical)

1. Keep scheduled uveitis visits and imaging—prevents silent damage. AAO

2. Follow the exact taper/biologic schedule—avoid sudden stops. PMC

3. Do TB/hepatitis screening and vaccine planning before biologics. FDA Access Data

4. Use infection precautions (hand hygiene; avoid sick contacts) on immunosuppression. FDA Access Data

5. Protect eyes from trauma and UV glare; follow post-procedure hygiene. FDA Access Data

6. Manage bone health (dietary calcium/vitamin D, weight-bearing activity) if on steroids. National Eye Institute

7. Stop smoking; it worsens general inflammatory risk. Mayo Clinic

8. Use adherence tools (reminders/pillboxes) to reduce missed doses. PMC

9. Coordinate care with primary/rheumatology for comorbidities and labs. PMC

10. Call promptly for new floaters, flashes, dark curtain, painful red eye, or sudden blur. National Eye Institute

When to see a doctor (now vs routine)

Seek urgent ophthalmic care for new floaters or flashes, sudden blur, a dark shadow, painful red eye, or after-injection symptoms like worsening pain, vision loss, or discharge—these can signal a flare, macular edema, retinal tear/detachment, high pressure, or infection. Routine visits should continue even when you feel well, because activity can return silently and imaging often detects relapse before symptoms. National Eye Institute+1

What to eat and what to avoid

Eat: (1) leafy greens and colored vegetables; (2) omega-3 fish (or clinician-approved alternatives); (3) lean proteins; (4) calcium/vitamin D sources when on steroids; (5) high-fiber whole grains. Avoid/limit: (6) smoking; (7) excess alcohol; (8) very high-sodium processed foods (pressure/glaucoma risk management); (9) excessive sugars if on steroids; (10) unvetted supplements that may interact with immunosuppressants—always discuss first. These steps support overall health; they do not replace medical therapy. Mayo Clinic+1

Frequently asked questions

1. Is birdshot contagious? No. It’s an autoimmune eye disease, not an infection. NCBI

2. Will I go blind? Many patients keep useful vision with early, steady treatment and monitoring, though flares can harm vision if untreated. AAO

3. Why test HLA-A29? It supports the diagnosis because birdshot is very strongly associated with HLA-A29. NCBI+1

4. Why so many scans? OCT and angiography find swelling or leakage early so therapy can be adjusted. AAO

5. Are steroids always needed? They’re often first-line to quiet inflammation; long-term, doctors add steroid-sparing agents or local implants to reduce steroid exposure. PMC

6. What if drops don’t help? Posterior uveitis often needs pills, injections, implants, or biologics because the inflammation is deep in the eye. PMC

7. Are there FDA-approved uveitis drugs? Yes: adalimumab (systemic), dexamethasone implant, and fluocinolone acetonide implants/insert; Xipere is approved for uveitic macular edema. FDA Access Data+4FDA Access Data+4FDA Access Data+4

8. Can biologics cause infections? Yes—labels carry boxed warnings; screening and monitoring cut risk. FDA Access Data
