Frequently Asked Questions

Sympathetic ophthalmia is a rare eye disease. It happens when one eye is injured or operated on, and the body’s immune system later starts attacking both eyes. The first eye is the one that was injured or had surgery. Doctors sometimes call it the “exciting” eye. The second eye becomes inflamed even though it was never hurt. Doctors call that second eye the “sympathizing” eye. The inflammation usually affects the whole eye (front, middle, and back). In simple words, the immune system gets confused after the first eye is opened by trauma or surgery, and it begins to see normal eye tissue as “foreign.” That mistake then causes swelling, light sensitivity, blurry vision, and other problems in both eyes.

Sympathetic ophthalmia is a rare but serious eye condition. It happens when the immune system becomes confused after a penetrating injury or intraocular surgery in one eye. The injured eye “spills” eye proteins that your immune system normally never sees. Your immune system then starts attacking those same proteins in both eyes, causing inflammation throughout the inside of the eye (a granulomatous panuveitis). The problem can appear weeks, months, or even years after the original injury or surgery. Without fast treatment, swelling can harm the retina and the optic nerve and permanently reduce vision. With early, strong, and steady treatment, many people keep useful vision.

Why it happens

Inside the eye there are special pigments and proteins, especially in a layer called the uvea and in cells that make melanin. These inner eye parts normally stay hidden from the immune system. When a deep injury or a surgery opens the eye, tiny bits of that inner eye tissue can leak or become exposed. The immune system notices those new proteins for the first time and makes a memory of them. Later, immune cells travel through the blood and attack the same normal proteins in both eyes. This causes a “granulomatous” inflammation, which means clumps of immune cells form and keep the swelling alive. Small yellow-white spots can appear under the retina. Doctors often call those spots Dalen-Fuchs nodules. The swelling can also cause fluid to collect under the retina (a “serous retinal detachment”), which blurs vision.

Sympathetic ophthalmia is rare. It can appear weeks, months, or even years after the first injury or surgery. Many people develop symptoms within the first year, but later cases are well known. Because it is uncommon, doctors always think about other causes of inflammation too, and they rule those out with tests.

Anyone with a penetrating eye injury or intraocular surgery (a surgery that goes inside the eyeball) can be at risk. Modern surgical methods and careful follow-up make the risk low, but it is not zero. People who had a severe injury with tissue loss or a retained foreign body have higher risk. People who need several eye operations, or operations that disturb the brown pigmented layer inside the eye (the uvea), may also be at higher risk.

Types of Sympathetic Ophthalmia (SO)

1) By trigger

Trauma-induced SO. This type follows a deep injury that opens the eyeball. The immune system gets exposed to inner eye proteins after the accident.
Surgery-induced SO. This type follows an operation that enters the eye, such as retinal surgery or complicated cataract surgery. Very careful modern surgery keeps this risk low, but it can still happen.

2) By time of onset after the trigger

Early-onset SO. Symptoms start within weeks to a few months. People notice light sensitivity, floaters, and blurred vision fairly soon after the event.
Delayed-onset SO. Symptoms start many months or even years later. The long gap can make the link to the old injury harder to see.

3) By main location of inflammation

Anterior-predominant uveitis. The front part of the eye (iris and ciliary body) is more inflamed, with redness, pain, and light sensitivity.
Posterior-predominant uveitis. The back of the eye (choroid and retina) is more affected, with floaters and blurred vision from fluid under the retina.
Panuveitis (full-eye inflammation). All parts are involved. This is common in SO.

4) By activity pattern

Active SO. Signs and symptoms are present now.
Quiescent SO. The eye is quiet after treatment, but flare-ups can return.
Relapsing SO. Periods of quiet are broken by new attacks if treatment is stopped or reduced too fast.

5) By severity

Mild to moderate SO. Symptoms are noticeable but respond well to treatment.
Fulminant SO. The attack is strong and rapid, with heavy inflammation, fluid under the retina, and faster vision loss without urgent care.

Causes

Important note: almost all real “causes” involve uveal exposure after an opening into the eyeball. The items below are the most common or documented settings that can trigger SO.

Penetrating eye injury with uveal exposure. A deep cut or puncture lets inside eye proteins escape and be seen by the immune system, starting the mistaken attack.
Retained intraocular foreign body. A small piece of metal, glass, or wood left inside the eye keeps the immune system stimulated for a long time.
Pars plana vitrectomy (retinal surgery). This surgery enters the eye and disturbs the retina and choroid. The risk is small but real.
Complicated cataract surgery with posterior capsule tear. When the back of the lens breaks, tissues behind the lens may be exposed or manipulated.
Penetrating keratoplasty (full-thickness corneal transplant). This surgery opens the eye and can expose uveal tissue during the procedure.
Repair of corneal or scleral laceration. After trauma, surgical repair itself is necessary but still involves manipulation of exposed inner tissues.
Scleral buckling with choroidal disturbance. Retinal detachment repair can sometimes disturb the pigmented layer under the retina.
Cyclodestructive procedures (e.g., cyclophotocoagulation). These glaucoma treatments target the ciliary body and can expose or alter uveal tissue.
Trabeculectomy or tube shunt surgery (rare trigger). These surgeries are for glaucoma; very rarely they are linked to SO when deeper tissues are affected.
YAG laser capsulotomy after cataract surgery (very rare). Most cases are safe, but isolated reports exist, often with other risk factors present.
Retinal cryotherapy or diathermy near the choroid. Intense cold or heat can disturb the pigmented layer and expose antigens.
Open-globe injury with delayed closure. The longer the eye stays open before surgical repair, the higher the chance of immune sensitization.
Severe blunt trauma causing occult uveal rupture. Even without an obvious cut, a hidden break in deep tissues can occur.
Endophthalmitis after injury or surgery. Infection can break down tissues and make the immune exposure worse.
Repeated intraocular surgeries. Many entries into the eye increase the total chance of antigen exposure over time.
Biopsy of uveal tumor (e.g., melanoma). Penetrating the choroid to get a sample can expose pigmented tissue proteins.
Complicated intraocular lens exchange. Re-entering the eye to change a lens can disturb the uveal tissues.
Pediatric intraocular surgery (rare). Children’s immune systems are very active; rare cases are reported after certain deep eye surgeries.
Retinal detachment with large choroidal breaks. The underlying pigmented layer may be torn, exposing more antigens.
Penetrating injuries with tissue loss and no early removal of a blind, devastated eye. When an eye is beyond repair and left in place for long, the immune system can remain stimulated; early removal in selected hopeless eyes has historically reduced SO risk.

Symptoms

Blurred vision. Things look foggy or smeared because swelling affects the clear eye layers and the retina.
Light sensitivity (photophobia). Bright light feels harsh or painful because the inflamed iris and cornea react strongly.
Redness. Small blood vessels on the white of the eye swell from inflammation and make the eye look red.
Eye pain or ache. The inflamed tissues and increased pressure can make the eye feel sore, heavy, or tender.
Floaters. Small moving spots or cobwebs appear because cells and debris float in the gel inside the eye.
Reduced night vision. Retinal swelling and fluid under the retina can make dim light vision worse.
Distorted vision (straight lines look wavy). Fluid under the macula or swelling in the retina bends the way images are formed.
Loss of part of the visual field. Inflammation can interrupt signals from certain retinal areas, creating blind spots.
Headache or brow pressure. Eye inflammation can cause referred pain around the eye and forehead.
Excess tearing. Irritation from inflammation triggers more tears.
Color vision changes. Colors may look dull or washed out when the macula or optic nerve is affected.
Glare and halos. Light scatters through cloudy tissues or inflammatory cells, causing rings or starbursts.
Tenderness around the eye. The tissues around the eye can be sore because of deep inflammation.
Double vision (rare). If swelling affects eye movement or the visual pathway, two images can appear.
A sudden drop in vision. A big flare with fluid under the retina, bleeding, or high pressure can cause a fast change in sight.

Diagnostic tests

Doctors usually combine these tests. The goal is to confirm inflammation that fits SO and to rule out other diseases that can look similar (like Vogt-Koyanagi-Harada disease, sarcoidosis, tuberculosis-related uveitis, syphilis, or intraocular lymphoma).

A) Physical examination

Visual acuity testing (reading the eye chart). This measures how clearly you see. It shows how much vision is affected and helps track improvement or worsening over time.
External inspection of the eyes and eyelids. The doctor looks for redness, swelling, tenderness, and discharge. This quick look tells how active the surface inflammation is.
Pupil examination and the swinging-flashlight test. The doctor checks how each pupil reacts to light and looks for a relative afferent pupillary defect, which can show optic nerve stress.
Confrontation visual fields. The doctor asks you to count fingers or detect movement from different directions to find any missing areas in your side vision.
Color vision testing (e.g., simple color plates). Changes in color vision can point to macula or optic nerve involvement from inflammation.

B) Manual / clinical slit-lamp and ophthalmoscopy tests

Intraocular pressure (IOP) measurement (applanation tonometry). High or low pressure can happen during inflammation. Measuring IOP helps guide safe treatment.
Slit-lamp biomicroscopy of the front of the eye. The doctor uses a microscope and a thin beam of light to look for cells and flare in the anterior chamber, keratic precipitates on the cornea, and iris changes.
Dilated fundus examination with indirect ophthalmoscopy. With the pupil widened, the doctor looks for vitreous cells, choroidal swelling, Dalen-Fuchs nodules, optic disc edema, and fluid under the retina.

C) Laboratory and pathological tests

Complete blood count (CBC), erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP). These show general inflammation and help screen for infection or blood problems.
Syphilis testing (e.g., RPR and confirmatory treponemal test). Syphilis can mimic SO and must be ruled out because the treatment is very different.
Tuberculosis screening (e.g., IGRA blood test). TB can cause uveitis that looks like SO; identifying TB changes the whole treatment plan.
Sarcoidosis screening (e.g., serum ACE and lysozyme). Elevated levels can point toward sarcoid uveitis, another condition that can look similar.
Autoimmune panel (e.g., ANA; sometimes ANCA or others as guided). These help look for systemic autoimmune diseases that can involve the eye.
Aqueous or vitreous sampling for PCR/cytology when needed. If doctors suspect infection or intraocular lymphoma, a small sample of eye fluid can be tested to confirm or exclude those problems.

D) Electrodiagnostic tests

Electroretinography (ERG). This test measures how the retina responds to light. Inflammation can reduce these signals. It helps document how much the retina is affected.
Electro-oculography (EOG). This test checks the function of the retinal pigment epithelium (RPE). Disturbance in this layer is common in SO.
Visual evoked potentials (VEP). This measures signals traveling from the eye to the brain. It helps find damage to the optic pathway from inflammation.

E) Imaging tests

Optical coherence tomography (OCT). OCT is like an ultrasound made with light. It shows fine layers of the retina and can reveal fluid under the retina or swelling in the macula.
Fluorescein angiography (FA). A dye is injected into a vein in the arm, and a special camera takes pictures of the retina as the dye passes through. Leakage patterns can show active inflammation and help track response to treatment.
Indocyanine green angiography (ICG). This dye test highlights the choroid (the pigmented layer under the retina). It is very helpful in SO because much of the inflammation starts in the choroid.

Non-Pharmacological Treatments (Therapies & Others)

These steps support but do not replace steroid and immunosuppressive therapy. Your eye specialist sets the core treatment plan.

Other agents used in select refractory cases include cyclophosphamide and chlorambucil (alkylators; potent and toxic, reserved for severe, specialist-managed cases).

Dietary Molecular Supplements

Supplements may offer modest anti-inflammatory support. They do not replace prescription therapy and may interact with medicines.

Omega-3s (EPA/DHA).
Dose: ~1–3 g/day combined EPA/DHA.
Function/Mechanism: produce pro-resolving mediators that gently calm inflammation; may aid tear film.

Folic acid (with methotrexate).
Dose: ~1 mg/day or as prescribed.
Function/Mechanism: reduces methotrexate mouth sores, GI upset, and lab toxicity without reducing benefit.

Immune-Modulating / Regenerative” Options

Important: There is no proven “hard immunity booster” for SO. In fact, treatment requires immune suppression or immune modulation, not “boosting.” The options below are specialist-only and some are off-label or experimental.

Rituximab (anti-CD20).
Dose patterns: 1000 mg IV on days 1 and 15, or 375 mg/m² weekly ×4 (specialist decides).
Function/Mechanism: depletes B cells that help drive autoimmunity. Useful in select refractory uveitis.
Note: infection risk; vaccine planning needed.
Tocilizumab (anti-IL-6).
Dose: ~8 mg/kg IV monthly or 162 mg SC weekly/biweekly.
Function/Mechanism: blocks IL-6 signaling; can help macular edema unresponsive to other agents.
JAK inhibitors (e.g., tofacitinib, upadacitinib).
Dose examples: tofacitinib 5 mg BID; upadacitinib 15 mg daily (specialist-guided).
Function/Mechanism: intercept multiple cytokine signals inside immune cells; used off-label in refractory cases.
Intravenous immunoglobulin (IVIG).
Dose: often ~0.4 g/kg/day for 3–5 days, then cycles.
Function/Mechanism: re-balances immune networks and neutralizes autoantibodies in some autoimmune conditions.
Autologous hematopoietic stem cell transplantation (AHSCT).
What it is: collect your stem cells, use chemotherapy to “reset” immunity, then reinfuse.
Function/Mechanism: aims to rebuild a less auto-reactive immune system.
Status: high-risk and experimental for ocular autoimmunity; considered only in extreme, refractory systemic autoimmune disease within trials/centers.
Mesenchymal stem cell (MSC) therapy.
What it is: infusion/injection of MSCs intended to release anti-inflammatory factors.
Function/Mechanism: paracrine immune modulation.
Status: experimental; variable protocols; discuss clinical trial options only—avoid commercial “stem cell clinics.”

Surgeries and Why They Are Done

Early enucleation of a severely destroyed eye (case-by-case).
Procedure: removal of a non-seeing, badly damaged eye soon after trauma.
Why: historically lowers SO risk when the eye is beyond repair; timing and ethics are individual—decided with the patient.
Pars plana vitrectomy.
Procedure: microscopic removal of inflamed vitreous gel and membranes.
Why: clears media, reduces inflammatory load, treats complications like traction or non-clearing hemorrhage.
Cataract surgery once inflammation is quiet.
Procedure: phacoemulsification with intraocular lens placement under steroid cover.
Why: steroids and inflammation often cause cataracts; surgery improves vision after disease control.
Glaucoma surgery (filtering or MIGS) if pressure stays high.
Procedure: creates new fluid outflow pathway or implants stents/valves.
Why: chronic steroid use or inflammation can raise IOP; uncontrolled high pressure damages the optic nerve.
Long-acting steroid implant placement.
Procedure: surgically insert fluocinolone (or inject dexamethasone implant).
Why: delivers steady steroid to the eye while minimizing systemic steroid exposure.

Practical Prevention Steps

Prevent eye injuries with protective eyewear at work and sports.
Immediate repair of open-globe injuries by an experienced team.
Avoid delays between injury and wound closure.
Careful surgical planning to minimize uveal exposure when intraocular surgery is necessary.
Limit repeat intraocular surgeries to truly needed procedures.
Perioperative anti-inflammatory plan (steroid cover as your surgeon advises).
Close follow-up for months to years after major eye trauma/surgery.
Rapid evaluation if any new symptoms arise—do not wait.
Control systemic risk factors (BP, diabetes) to protect retinal health.
Avoid evisceration after open-globe rupture unless your specialist explicitly advises; discuss risks and alternatives.

When to See a Doctor—Immediately

New blurry vision, floaters, or light sensitivity after eye injury or surgery.
Red, painful eye that does not improve in 24–48 hours.
Sudden distortion, new dark curtain, or flashes.
Headache with eye pain or nausea plus eye symptoms.
Any SO history with new symptoms—even mild ones.

SO is an emergency. Same-week or even same-day evaluation can save vision.

What to Eat and What to Avoid

Eat more: oily fish (salmon, sardines) 2–3×/week for omega-3s.
Eat more: leafy greens, colorful vegetables, berries, and legumes for antioxidants.
Eat more: nuts and seeds (walnuts, flax, chia) in small portions daily.
Stay hydrated: regular water intake supports eye and body function.
Include: fermented foods or a doctor-approved probiotic for gut–immune balance.
Limit: ultra-processed foods, refined sugars, and trans fats that drive inflammation.
Limit: excess salt that may worsen fluid retention and pressure.
Avoid: grapefruit if on cyclosporine or tacrolimus (dangerous interactions).
Avoid: unpasteurized dairy, raw eggs/meats, and buffets if you take immunosuppressants (infection risk).
Limit alcohol; avoid with methotrexate; discuss safe amounts with your team.

Frequently Asked Questions

Is sympathetic ophthalmia contagious?
No. It is an autoimmune reaction, not an infection you can catch or spread.
Can SO appear long after the injury?
Yes. It can appear weeks to years later. Lifelong awareness is important.
Which eye is at risk—the injured one or the other one?
Both eyes are at risk. The other eye (sympathizing eye) is the one doctors work hardest to protect.
Will I need steroids?
Almost always yes, at least at the beginning, to stop vision-threatening inflammation quickly.
How long will I take treatment?
Many patients need months to years of steroid-sparing medicine to keep the disease quiet and protect vision.
Are biologic medicines safe?
They can be very helpful but have infection risks. You will have screening (e.g., TB) and regular labs.
Can I stop medicines when I feel better?
Do not stop on your own. Stopping suddenly can cause a rebound flare. Tapers are slow and supervised.
Do supplements cure SO?
No. Supplements may offer small supportive benefits. Prescription therapy is essential.
Will I go blind?
With early diagnosis, strong treatment, and good follow-up, many people maintain useful vision. Delay raises risk.
Is surgery always needed?
Not always. Surgery is for complications (cataract, pressure, membranes) or rare preventive/ethical decisions after catastrophic injury.
Can contact lenses be used?
Usually avoid during flares. After quiet periods, ask your doctor; strict hygiene is vital.
Can I work and drive?
Often yes, but during flares you may need adjustments. Follow your doctor’s advice and local rules for vision standards.
What about pregnancy?
Planning is important. Some drugs are unsafe in pregnancy. Tell your team early to switch to safer options.
How do doctors know it’s SO and not infection?
They combine history (injury/surgery), exam, imaging, and lab tests to rule out infections like TB or syphilis before using strong immunosuppression.
What if first-line drugs don’t work?
Specialists escalate to other immunosuppressants or biologics, and sometimes use local implants or vitrectomy. Rarely, clinical trials are appropriate.
