Birdshot Chorioretinopathy (BCR)

Birdshot chorioretinopathy (BCR) is a rare, long-lasting inflammation inside both eyes. It affects the choroid (the blood-rich layer under the retina) and the retina (the light-sensing layer). Doctors call it a form of posterior uveitis, because the inflammation lives in the back of the eye. People usually develop it in mid-life. It is more common in individuals of European ancestry. Most patients have a special immune marker in their genes called HLA-A29. This gene link is very strong. It does not mean the gene “causes” the disease by itself. It means the gene sets the stage for the immune system to react in an unusual way.

Birdshot chorioretinopathy is a rare, long-lasting inflammation at the back of the eye (retina and choroid). It usually affects both eyes and is strongly linked to the HLA-A29 genetic marker. People notice symptoms such as blurry vision, floaters, glare, trouble seeing at night, and sometimes color changes. Doctors confirm the diagnosis with a full eye exam and imaging tests like OCT, fluorescein angiography, indocyanine green angiography, and often an electroretinogram. Because BCR can slowly damage vision, long-term monitoring and treatment are important to keep inflammation quiet and protect sight. American Academy of Ophthalmology+3PMC+3Frontiers+3

BCR gets its name from the look of the back of the eye. On exam, the doctor can see many pale, oval spots that radiate from the optic nerve head. The pattern looks like the underside of a bird called a woodcock or “birdshot,” which is why the name stuck. The spots are not the whole story. The disease also inflames small retinal blood vessels and the deeper choroid. This inflammation can blur vision, wash out color, reduce contrast, and cause “sparkles” of light or floaters. Without treatment, the disease can slowly damage the retina. With regular care and modern medicines, most patients keep useful vision.

Other names

Doctors and papers may use these names for the same disease:

• Birdshot retinochoroidopathy

• Birdshot retino-choroiditis

• HLA-A29 uveitis

• Vitiliginous chorioretinitis (older term; “vitiliginous” refers to the pale patches)

All of these describe the same clinical picture: bilateral, chronic, posterior uveitis with cream-colored choroidal spots and a strong HLA-A29 link.

Types

There is no single official “type” list like in some diseases. But in clinic, doctors often think in the following helpful ways:

1. By activity

• Active BCR: signs of ongoing inflammation (new leakage on angiography, fluid in or under the macula on OCT, vascular leakage, active vitritis).

• Quiet/Inactive BCR: old birdshot lesions with little or no leakage or swelling, and stable tests.

2. By what is most affected

• Retinal vasculitis–predominant: vessel leakage and cystoid macular edema (fluid in the center of vision) stand out.

• Choroid-predominant: indocyanine green angiography shows many “dark dots,” and OCT/OCTA show choriocapillaris involvement.

3. By stage

• Early: few visible spots; imaging (especially indocyanine green) shows more lesions than the doctor can see; ERG may already slow.

• Established: many classic birdshot spots are visible; tests show reduced cone/rod function; flare-ups may occur.

• Late: thinning of outer retina, loss of the “ellipsoid zone” on OCT, and reduced ERG responses; color/contrast remain sensitive.

These categories are practical, not rigid. A single patient can move between them over time.

Causes

Important note: BCR is idiopathic, meaning no single proven “cause” is known. The items below are best understood as contributors, risks, or mechanisms that research supports to different degrees. HLA-A29 seems necessary in most cases, but it is not sufficient by itself.

1. HLA-A29
   The strongest known association. Over 90–95% of patients carry it. It shapes how immune cells present retinal/choroidal peptides.

2. ERAP2 genetic variants
   ERAP2 helps trim peptides that HLA molecules present. Certain variants pair with HLA-A29 and may alter immune recognition.

3. ERAP1 variants
   Like ERAP2, ERAP1 also edits peptides. Specific combinations with HLA-A29 may raise risk.

4. T-cell–mediated autoimmunity
   Overactive T cells may target retinal or choroidal antigens, driving chronic inflammation.

5. Antigen presentation in the choroid
   Choroidal immune cells present local peptides to T cells, possibly amplifying attack on the choriocapillaris.

6. Molecular mimicry after infection (hypothesis)
   A past infection might present look-alike peptides that “train” immunity to later target the eye. This remains a theory, not a proven trigger.

7. Innate immune activation
   Cytokines and chemokines (cell signals) promote ongoing inflammation in choroid and retina.

8. Breakdown of immune privilege
   The eye is usually protected from immune attack. In BCR, that protection fails, allowing persistent inflammation.

9. Retinal autoantibodies (some reports)
   Some patients have antibodies against retinal proteins. Their exact role is unclear.

10. Choriocapillaris microvascular injury
    Inflammation of the tiny choroidal vessels may starve photoreceptors of oxygen and nutrients.

11. Complement pathway involvement (emerging data)
    Some studies suggest complement activation may contribute, though evidence is early.

12. Age-related immune changes
    Mid-life changes in immune regulation may allow disease to appear.

13. Environmental co-factors (uncertain)
    No specific toxin or diet is proven. Environment may still modulate risk in genetically primed people.

14. Female sex (slight skew)
    Some series suggest a mild female predominance, but the disease affects all sexes.

15. European ancestry
    Likely linked to HLA-A29 frequency, not to ethnicity itself.

16. Smoking (general immune effects)
    Smoking can worsen many inflammatory diseases; specific BCR data are limited, but avoidance is wise.

17. Vitamin D status (speculative)
    Vitamin D affects immune balance; direct BCR evidence is limited.

18. Gut microbiome (theoretical)
    Microbiome can shape systemic immunity. Specific BCR links are unproven.

19. Second-hit model
    Genetic risk + an extra immune trigger (infection, stressor) may be needed to start disease.

20. Persistent cytokine loops
    Once started, self-feeding inflammation can keep going unless actively treated.

Symptoms

1. Blurred vision
   Inflammation and fluid in the macula make fine detail fuzzy. Reading and facial recognition get hard.

2. Floaters
   Cells and proteins in the vitreous cast shadows that drift across vision.

3. Photopsias (flashes/sparkles)
   Irritated retinal cells misfire, so you see brief lights or shimmering.

4. Reduced color vividness
   Inflamed cone pathways make colors look faded or dull.

5. Poor contrast sensitivity
   Gray-on-gray or low-light tasks (driving at dusk, reading faint print) become difficult.

6. Night vision trouble (nyctalopia)
   Rods can be impaired, so seeing in dim light is harder.

7. Peripheral vision gaps
   Inflammation can create blind spots, felt as “missing pieces” off to the side.

8. Metamorphopsia (bent lines)
   Macular swelling distorts the fine grid of photoreceptors, so straight lines look wavy.

9. Light sensitivity (photophobia)
   Inflamed tissues react strongly to bright light, causing discomfort.

10. Eyestrain and headache
    Working harder to see can trigger frontal headaches or general fatigue.

11. Difficulty with color discrimination
    Telling close shades apart (e.g., navy vs. black) gets tricky.

12. Reading speed drops
    Frequent re-focusing and reduced contrast slow reading.

13. Glare problems
    Headlights and sunlight scatter more in inflamed eyes, causing halos and glare.

14. Depth perception changes
    If one eye is more affected, judging distance can feel off.

15. Symptom fluctuation
    Good days and bad days reflect changes in inflammation and fluid.

Diagnostic tests

A) Physical exam (doctor’s in-office eye exam)

1. Best-corrected visual acuity
   You read letters to measure detail vision. Changes over time track disease control.

2. Pupil exam
   Checks if both eyes respond equally. Severe retinal dysfunction can create a relative afferent defect.

3. Intraocular pressure
   Steroids (used to treat BCR) can raise pressure. Regular checks protect the optic nerve.

4. Slit-lamp exam of the anterior segment
   The front of the eye is usually quiet in BCR, but mild inflammation can occur. Baseline matters.

5. Dilated fundus exam
   The doctor looks at the retina and choroid. Cream-colored oval spots, usually nasal to the macula and radiating from the disc, are classic. Vitritis and vascular sheathing may be seen.

B) “Manual”/functional tests (psychophysical vision tests you perform)

6. Amsler grid
   You look at a grid to detect wavy lines or missing boxes. It flags macular distortion.

7. Color vision testing (e.g., Ishihara or D-15)
   Assesses cone function. Subtle color losses are common in BCR.

8. Contrast sensitivity (e.g., Pelli-Robson)
   Measures the faintest gray you can detect. It is very sensitive to disease activity.

9. Automated perimetry (visual field test)
   Maps blind spots and sensitivity. BCR often causes paracentral and mid-peripheral defects.

10. Dark adaptation
    Measures how quickly your eyes recover in the dark. Rod pathway stress can slow recovery.

C) Lab and pathological tests (mostly to support or exclude mimics)

11. HLA-A29 typing
    A strong supportive test. A positive result in the right clinical picture makes BCR very likely.

12. Syphilis serology (RPR and treponemal test)
    Rules out a treatable mimic of posterior uveitis.

13. Tuberculosis testing (IGRA/PPD)
    Excludes TB uveitis, which needs different treatment.

14. Sarcoidosis markers (ACE, lysozyme) and chest imaging when indicated
    Sarcoid can copy some findings; screening helps if there are suggestive signs.

15. Basic inflammatory labs (CBC, ESR/CRP) guided by history
    Non-specific but can guide the broader uveitis work-up; BCR itself has no unique blood marker.

D) Electrodiagnostic tests (measure retinal electricity)

16. Full-field ERG (cone and rod responses; 30-Hz flicker)
    Often shows delayed cone flicker and reduced amplitudes. It is excellent for tracking function over years.

17. Multifocal ERG
    Samples many small retinal regions at once. It can pinpoint localized dysfunction near the macula.

18. Pattern ERG
    Assesses macular/inner retinal pathways. Helpful when acuity seems better than function.

E) Imaging tests (show anatomy and inflammation)

19. Optical coherence tomography (OCT)
    Cross-section “slices” of the retina. Detects cystoid macular edema, ellipsoid zone loss, and thinning. Key for monitoring response to therapy.

20. Fluorescein angiography (FA)
    Dye pictures of retinal vessels. Shows leakage from vessels and the optic disc, capillary non-perfusion, and macular edema.

21. Indocyanine green angiography (ICGA)
    Highlights the choroid. In BCR it often shows many hypofluorescent dark dots—more than are visible on exam. Very sensitive to choroidal disease load.

22. Fundus autofluorescence (FAF)
    Maps lipofuscin in the retinal pigment epithelium. Hypo- or hyper-autofluorescent patches mark stress or loss.

23. Optical coherence tomography angiography (OCTA)
    Non-dye flow maps. Can show choriocapillaris flow voids and macular capillary changes.

24. Ultra-widefield imaging
    Captures large areas of retina to document the full spread of lesions and vessel leakage.

25. Color fundus photography
    Baseline and follow-up photos record the number and appearance of birdshot spots.

26. B-scan ocular ultrasound (if view is hazy)
    Useful when media are cloudy; can show posterior hyaloid or other complications when the doctor cannot see in.

Non-pharmacological treatments (therapies & others)

1) Education & disease self-management
Description: Learning what BCR is, how it behaves, what “flares” look like, and why follow-up matters helps people act early when vision changes. Education covers warning signs (new floaters, haze, pain, light sensitivity), how to use drops or systemic medicines correctly, and safe daily habits (lighting, glare control, driving limits). Written “flare plans” and symptom diaries make care smoother.
Purpose: Reduce delays to care and improve adherence.
Mechanism: Knowledge lowers anxiety and improves timely reporting, which prevents prolonged inflammation and retinal damage. NCBI+1

2) Regular monitoring & structured follow-up
Description: BCR needs scheduled visits, usually every 1–3 months during active disease, then spaced out when quiet. Visits often include visual acuity, dilated exam, OCT to check macular edema, and sometimes FA/ICG or ERG to track deeper retinal function. A clear follow-up plan reduces “silent” progression.
Purpose: Catch relapse and macular edema early.
Mechanism: Imaging and functional tests detect inflammation and edema before major vision loss, guiding treatment adjustments in time. American Academy of Ophthalmology+1

3) Blue-light and glare management
Description: Many patients report glare and light sensitivity. Using polarized sunglasses outdoors, anti-reflective coatings, brimmed hats, and warm-tinted lenses indoors can ease discomfort. Adjusting screen brightness and using night-mode on devices reduces strain.
Purpose: Improve daily comfort and reading/working tolerance.
Mechanism: Filters reduce scattered light on inflamed retinal tissue, lowering photostress and symptoms without changing disease activity. EyeWiki

4) Low-vision rehabilitation (when needed)
Description: If vision is reduced despite control of inflammation, low-vision services can help. Tools include high-contrast reading materials, electronic magnifiers, large-font settings, task lighting, and orientation training.
Purpose: Maintain independence and quality of life.
Mechanism: Optical and environmental adaptations improve effective visual function despite retinal sensitivity loss. NCBI

5) Smoking cessation
Description: Stopping smoking supports eye and whole-body health and can lower overall inflammatory burden. Programs include counseling, nicotine replacement, and behavioral support.
Purpose: Reduce systemic inflammation risks and vascular stress that can worsen ocular disease outcomes.
Mechanism: Quitting reduces pro-inflammatory cytokines and oxidative stress that can harm retinal tissues. (General inflammation and ocular-health rationale from standard ophthalmic and public-health guidance.) NCBI

6) Sleep optimization
Description: Good sleep (7–9 hours, regular schedule, dark cool room) improves daytime visual comfort, coping, and medication adherence. Treating sleep apnea where present helps systemic inflammation.
Purpose: Support immune balance and consistent self-care.
Mechanism: Regular sleep stabilizes stress hormones and immune signaling that can influence chronic inflammatory diseases. (General mechanistic link; practical in chronic uveitis care.) NCBI

7) Stress-reduction and mental-health support
Description: Chronic eye disease can cause worry and low mood. Mindfulness, brief CBT-style strategies, or counseling reduce distress and improve adherence to complex regimens.
Purpose: Improve coping, reduce flare-related anxiety, and support long-term follow-up.
Mechanism: Stress hormones affect immune activity; reducing stress can complement medical therapy in chronic inflammatory conditions. (General supportive care principle in chronic uveitis.) NCBI

8) Cardiometabolic risk control
Description: Controlling blood pressure, blood sugar, and lipids protects retinal circulation. Coordination with primary care for hypertension, diabetes, or dyslipidemia is key.
Purpose: Maintain retinal perfusion and reduce additive risks to vision.
Mechanism: Healthy vessels and metabolic balance support retinal health while inflammation is treated. (General retinal-health principle.) NCBI

9) Workplace/reading ergonomics
Description: Use high-contrast fonts, larger text, adequate task lighting, and frequent breaks (20-20-20 rule). Anti-glare screens and line guides can help when reading long documents.
Purpose: Reduce eyestrain and improve productivity.
Mechanism: Ergonomics decrease visual demand on a retina that may be light-sensitive or have subtle functional loss. EyeWiki

10) Vaccination review (non-live)
Description: Before or during immunosuppressive therapy, clinicians review vaccines (e.g., influenza, pneumococcal, COVID-19). Live vaccines are usually avoided while immunosuppressed.
Purpose: Lower infection risk while on systemic therapy.
Mechanism: Vaccination supports immune protection when disease or treatment weakens defenses. (Standard practice with systemic immunosuppression.) PubMed

11) Driving safety adjustments
Description: Night driving can be hard due to glare and nyctalopia. Limiting night driving, using anti-glare glasses, and planning well-lit routes improves safety.
Purpose: Prevent accidents and reduce stress.
Mechanism: Practical avoidance of high-glare conditions that trigger symptoms. EyeWiki

12) Adherence tools
Description: Use smartphone reminders, pillboxes, and written dosing calendars—especially when oral drugs, injections, or implants are part of care.
Purpose: Keep inflammation controlled consistently.
Mechanism: Better adherence reduces relapse and macular edema risk. PubMed

Dietary molecular supplements (adjuncts)

These do not treat BCR by themselves. They may support general eye/immune health alongside prescribed therapy. Always discuss with your doctor to avoid interactions.

1) Omega-3 fatty acids (EPA/DHA)
Description (~150 words): Omega-3s from fish oil can gently lower systemic inflammatory signaling. In eye care, omega-3s are mainly studied for dry-eye symptoms and general cardiovascular benefits. For BCR, they are an adjunct—meant to support comfort and overall health, not to replace immunosuppression. Choose quality-controlled products to avoid contaminants.
Dosage: Commonly 1–2 g/day combined EPA+DHA (check interactions with anticoagulants).
Function/Mechanism: Competes with arachidonic acid pathways and yields pro-resolving mediators that can modestly calm inflammation system-wide. PubMed

2) Vitamin D3
Description: Many people are low in vitamin D, which plays a role in immune regulation. Correcting deficiency may support balanced immune responses during chronic inflammatory disease. Test levels first.
Dosage: Often 800–2000 IU/day for maintenance; higher, time-limited doses for deficiency per clinician.
Function/Mechanism: Modulates T-cell differentiation and cytokine profiles toward less auto-reactivity. PubMed

3) Curcumin (turmeric extract, high-bioavailability)
Description: Curcumin has antioxidant and anti-inflammatory properties in lab and small clinical contexts. It can color stools/yellow and interact with anticoagulants.
Dosage: Varies; many use 500–1000 mg/day of enhanced-absorption formulations.
Function/Mechanism: Inhibits NF-κB and COX/LOX pathways, potentially reducing inflammatory mediator production. PubMed

4) Lutein/zeaxanthin
Description: Macular carotenoids concentrate in the retina and help filter high-energy light. While BCR is inflammatory, protecting macular resilience is sensible.
Dosage: Often lutein 10 mg + zeaxanthin 2 mg/day.
Function/Mechanism: Antioxidant light-filtering pigments that support macular health. PubMed

5) Coenzyme Q10
Description: A mitochondrial cofactor with antioxidant activity; sometimes used to support retinal energy metabolism.
Dosage: 100–200 mg/day.
Function/Mechanism: Electron-transport antioxidant support; theoretical retinal benefits. PubMed

6) Resveratrol
Description: Polyphenol with antioxidant and anti-inflammatory actions; human ocular evidence is limited.
Dosage: 150–500 mg/day in supplements.
Function/Mechanism: Modulates inflammatory signaling (e.g., NF-κB) and oxidative stress. PubMed

7) NAC (N-acetylcysteine)
Description: Precursor to glutathione; sometimes used for oxidative-stress support. May cause GI upset.
Dosage: 600–1200 mg/day.
Function/Mechanism: Boosts intracellular antioxidant capacity (glutathione). PubMed

8) Magnesium
Description: Broad health cofactor; deficiency is common and can affect muscle and nerve function, sleep, and stress.
Dosage: 200–400 mg/day elemental magnesium (watch GI tolerance).
Function/Mechanism: Cofactor in >300 reactions; supports general well-being during chronic disease care. PubMed

9) Vitamin B-complex
Description: Supports energy metabolism and nerve health; useful if diet is limited.
Dosage: Per standard B-complex supplement.
Function/Mechanism: Cofactors in cellular energy and repair. PubMed

10) Probiotics (general)
Description: Gut-immune crosstalk is active in auto-inflammation research. A balanced diet plus a simple probiotic may support GI comfort while on medications.

Immunity-booster / regenerative / stem-cell” drugs

There are no FDA-approved “stem-cell drugs” or regenerative medicines approved specifically to treat birdshot chorioretinopathy. Care relies on anti-inflammatory and immunosuppressive strategies (systemic or local) and, when appropriate, steroid implants or biologics. Experimental cellular therapies are being studied for some eye conditions, but they are not standard of care for BCR. Rely on proven uveitis therapies listed above and discuss clinical trials with your uveitis specialist if you are interested in research options. PubMed

If your audience expects six entries, you can frame safe, approved “immune-modulating” options already above (e.g., adalimumab, methotrexate, mycophenolate, azathioprine, cyclosporine, tacrolimus) as the practical immune-modulating toolkit—but be explicit that these are not “immunity boosters”; they safely reduce over-active immunity to protect vision. PubMed

Surgeries / procedures (what they are and why done)

1) Intravitreal steroid implant placement (YUTIQ® or OZURDEX®)
Procedure: Office-based intravitreal insertion after antisepsis and local anesthesia.
Why done: Long-acting local steroid to prevent or treat posterior uveitis relapses and macular edema when drops or systemic therapy are not enough or not tolerated. Monitor for IOP rise and cataract. FDA Access Data+1

2) Periocular or intravitreal steroid injections (triamcinolone)
Procedure: Office injection around or inside the eye.
Why done: Short- to medium-term control of inflammation or macular edema; often used as a bridge or when one eye needs extra help. (Widely used in noninfectious uveitis practice.) PubMed

3) Cataract surgery
Procedure: Phacoemulsification with intraocular lens implantation once inflammation is controlled.
Why done: Long-term steroids and inflammation can cause cataract; surgery restores clarity and improves vision potential. NCBI

4) Glaucoma surgery or laser
Procedure: MIGS, trabeculectomy, tube shunt, or selective laser trabeculoplasty depending on IOP status.
Why done: Steroids and uveitis can raise eye pressure; surgery protects the optic nerve when drops aren’t enough. NCBI

5) Pars plana vitrectomy (selected cases)
Procedure: Operating-room removal of vitreous gel.
Why done: Clear dense floaters, manage complications, or assist with concurrent procedures; may also help reduce inflammatory load in selected patients. NCBI

When to see doctors

See your eye doctor urgently if you notice new floaters, cloudy or hazy vision, eye pain, severe light sensitivity, sudden color or field changes, or any rapid drop in vision—these can mean a flare or macular edema that needs quick treatment. Keep routine visits exactly as scheduled, because BCR can progress with few symptoms. If you take steroids, biologics, or other immunosuppressants, also call if you develop fever, persistent cough, or signs of infection, because medicines may need to be paused or adjusted. Coordinate care with your primary-care doctor for vaccines and health checks while immunosuppressed. American Academy of Ophthalmology+1

What to eat & what to avoid

What to eat:

1. Plenty of vegetables and fruits with colorful carotenoids (greens, orange/yellow) to support antioxidant defenses.
2. Omega-3-rich fish (salmon, sardine) 1–2×/week or as advised.
3. Whole grains and legumes for fiber and stable energy while on long-term meds.
4. Lean proteins and dairy or fortified alternatives to support healing and bone health (especially with steroids).
5. Hydration: regular water intake to feel better and maintain general health. PubMed

What to avoid:

1. Smoking and secondhand smoke (pro-inflammatory).
2. Excess alcohol, especially with liver-metabolized drugs like methotrexate or azathioprine.
3. Very high-sodium foods if steroids raise blood pressure.
4. Grapefruit if on cyclosporine or tacrolimus (drug interactions).
5. Unverified supplements that may interact with immunosuppressants. Always clear new products with your doctor. PubMed

Frequently asked questions (FAQ)

1) Is Birdshot chorioretinopathy genetic?
It is strongly associated with HLA-A29, a genetic marker, but not everyone with HLA-A29 develops BCR. Environment and the immune system also play roles. Frontiers

2) Can BCR go away by itself?
It usually needs long-term care. Periods of quiet can occur, but untreated or undertreated inflammation can still damage the retina over time. PMC+1

3) Why are steroids used and then reduced?
Steroids act fast to calm inflammation, but long-term use can cause pressure rise, cataracts, and systemic effects. Doctors taper steroids and switch to steroid-sparing therapies for safety. FDA Access Data+1

4) What is a steroid implant and how long does it last?
YUTIQ can last up to about 3 years, while OZURDEX lasts months; both reduce inflammation locally but can raise eye pressure and cause cataract, so monitoring is essential. FDA Access Data+1

5) Are biologics like adalimumab safe?
They can be very effective but carry risks like serious infections. Screening (e.g., TB) and regular monitoring reduce risks. Discuss vaccination and illness precautions with your team. FDA Access Data

6) Will I need surgery?
Some people need cataract or glaucoma surgery after years of disease or steroid use. Choice depends on your pressure, lens clarity, and stability of inflammation. NCBI

7) Can diet cure BCR?
No diet cures BCR. A balanced, anti-inflammatory eating pattern supports overall health while proven medical treatments control the disease. PubMed

8) Can I still work or study?
Most people can, with lighting and screen adjustments, planned breaks, and low-vision aids if needed. Share any new symptoms early. EyeWiki

9) Is driving safe?
Driving may be fine when vision is stable, but night glare can be hard. Adjust habits and use anti-glare strategies; your doctor can advise based on your exams. EyeWiki

10) Do I need frequent blood tests?
Yes—if you take systemic immunosuppressants. Tests track blood counts and organ function to keep you safe. PubMed
