Butterfly-Shaped Pigmentary (Pattern) Macular Dystrophy

Butterfly-shaped pigmentary macular dystrophy (often shortened to “butterfly-shaped pattern dystrophy”) is a rare, inherited eye condition. It affects the macula, the central part of the retina that gives sharp, straight-ahead vision. Pigment builds up in the retinal pigment epithelium (RPE) in a shape that looks like a butterfly with 3–5 “wings.” Many people notice few or no symptoms at first. Over years, some people develop blurred central vision, wavy lines, or small blank spots. The condition can look like age-related macular degeneration (AMD), but it is different and usually progresses more slowly. EyeWiki+2Orpha+2

Butterfly-shaped pigmentary macular dystrophy is a rare, inherited eye condition that mainly affects the center of the retina (the macula). In this disease, waste material (called lipofuscin) builds up in the retinal pigment epithelium (RPE). This makes a butterfly-like pattern of dark and light patches when the back of the eye is photographed. Many people keep good vision for years, but some can develop blurry central vision, distorted lines, or problems reading. A small number develop a serious complication called choroidal neovascularization (CNV)—new, leaky blood vessels under the retina—which can cause faster vision loss and may need treatment. The condition is usually passed in families in an autosomal-dominant way. Mutations in the PRPH2 gene are the best-known cause of pattern dystrophies; rare cases link to CTNNA1. Diagnosis uses eye exam plus imaging (OCT, autofluorescence, angiography) and sometimes genetic testing. There is no drug that cures the dystrophy itself. Care focuses on monitoring, low-vision support, counseling, and treating complications like CNV with anti-VEGF injections. PMC+3EyeWiki+3NCBI+3

Other names

• Butterfly-shaped pattern dystrophy (BSPD or BPD)

• Butterfly-shaped pigment dystrophy of the fovea

• Pattern dystrophy of the RPE, butterfly type

• PRPH2-associated pattern macular dystrophy (when a PRPH2 gene change is found) EyeWiki+2JAMA Network+2

In this disorder, the RPE does not handle visual cycle by-products normally. Lipofuscin accumulates in specific macular patterns that look like wings. FAF imaging shows these deposits as areas that are brighter or darker than normal, and OCT shows changes in the outer retina and RPE. Over time, some people develop outer retinal atrophy at the center, and rarely new leaky vessels (choroidal neovascularization, CNV) that can worsen vision quickly. ScienceDirect+1

Types

Doctors mainly use the pattern on imaging to describe types. The butterfly type itself sits within a family called pattern dystrophies. You may see:

1. Classic butterfly type – 3–5 wing-like arms of pigment centered on the fovea. EyeWiki

2. Butterfly with vitelliform material – butterfly arms with small egg-yolk-like deposits. NCBI

3. Butterfly variant linked to specific PRPH2 mutations – similar look, variable severity among families. PMC+1

4. Butterfly-like pattern from other genes (rarer) – for example CTNNA1 variants can produce a butterfly pattern that mimics PRPH2 disease. PMC

5. Butterfly pattern in systemic disease – occasionally reported in myotonic dystrophy with matching FAF changes. JSTAGE

Causes

Although “butterfly-shaped” describes a look, the main cause is genetic. Below are common genetic and biologic drivers and known contributors:

1. Autosomal dominant inheritance (one affected parent can pass it on). NCBI

2. PRPH2 (RDS) gene variants – the most frequent cause; peripherin-2 supports photoreceptor outer segments. JAMA Network+1

3. Dominant-negative PRPH2 effects – mutant protein interferes with normal peripherin-2. faseb.onlinelibrary.wiley.com

4. PRPH2 C213 variants – specific cysteine changes have been tied to a butterfly phenotype. faseb.onlinelibrary.wiley.com

5. Digenic interaction (PRPH2 with ROM1) – rare double-gene mechanism worsening outer-segment structure. PMC

6. CTNNA1 variants – can produce butterfly-like macular lesions. PMC

7. ABCA4 variants – occasionally yield pattern dystrophy-like maculas overlapping with Stargardt spectrum. NCBI

8. BEST1 variants – in some families, adult-onset vitelliform/pattern features overlap. NCBI

16. RPE-photoreceptor interface dysfunction – structural and functional coupling fails. NCBI

17. Visual cycle by-product overload (A2E and related) – contributes to FAF signal. ScienceDirect

18. Rare systemic associations (e.g., myotonic dystrophy) – likely shared retinal vulnerability. JSTAGE

19. Penetrance and variable expressivity – some carriers have few signs; others have clear butterfly wings. PMC

20. Environmental contributors (possible) – factors like smoking/oxidative stress are suspected modifiers, though genetics dominates. (Review-based.) NCBI

Diagnostic tests

A) Physical exam (in-clinic checks)

1. Best-corrected visual acuity – letter chart measures central clarity; tracks change over time. NCBI

2. Pupil exam – rules out optic nerve problems; usually normal in this disease. NCBI

3. Slit-lamp exam with dilated funduscopy – doctor looks at the macula; sees the butterfly pigment arms. EyeWiki

4. Intraocular pressure and lens check – screens for other issues that can affect vision. NCBI

B) Manual/bedside vision tests

5. Amsler grid – patient looks at a square grid; wavy or missing boxes suggest macular change. NCBI

6. Near-reading card – checks functional reading vision at a set distance. NCBI

7. Color vision plates – detects subtle color loss common in macular disease. NCBI

8. Contrast sensitivity test – measures how well faint letters or low-contrast patterns are seen. NCBI

C) Laboratory & pathological (molecular) tests

9. Targeted gene panel for inherited retinal disease – looks for PRPH2 and other genes (e.g., CTNNA1, ABCA4, BEST1). A positive result confirms the cause and guides family screening. PMC+2PMC+2

10. Sanger confirmation – validates a panel finding in PRPH2 or other genes. PMC

11. Segregation testing in relatives – checks if the variant tracks with the disease in the family. PMC

13. (Rare) Histopathology – research reports show lipofuscin/RPE changes consistent with the clinical picture. Not done in routine care. JAMA Network

D) Electrodiagnostic tests

14. Full-field electroretinogram (ffERG) – often normal or mildly reduced because the disease is macula-focused; helps exclude diffuse retinal dystrophies. NCBI

15. Multifocal ERG (mfERG) – maps central retina function; shows depressed responses in the macular area. NCBI

16. Electro-oculogram (EOG) – tests RPE function; may be near normal or mildly abnormal. NCBI

E) Imaging tests

18. Fundus photography – documents the butterfly shape over time. EyeWiki

19. Fundus autofluorescence (FAF) – highlights lipofuscin; shows bright/dark butterfly wings and helps watch for spread or atrophy. ScienceDirect

20. Optical coherence tomography (OCT) – cross-section images show outer retinal/RPE changes; monitors atrophy or fluid. OCTA (angiography) can screen for CNV without dye. Fluorescein angiography (FA) and ICG angiography help confirm or exclude CNV when vision drops suddenly. NCBI

Non-pharmacological treatments (therapies & other supports)

1. Regular retina follow-up (6–12 months, sooner with symptoms)
   Purpose: Detect change early, especially CNV, which is treatable.
   Mechanism: Clinical exam plus OCT/OCT-A and fundus autofluorescence track RPE and photoreceptor status; new subretinal fluid, hemorrhage, or pigment epithelial detachment triggers treatment. Early detection improves outcomes if CNV develops. EyeWiki+1

2. Amsler grid self-monitoring at home
   Purpose: Help patients notice sudden distortion or missing spots in central vision.
   Mechanism: A simple grid tests macular function; new wavy lines or blank areas suggest fluid or bleeding from CNV—an urgent sign to see the retina specialist. NCBI

3. Low-vision rehabilitation (LVR)
   Purpose: Maximize reading, mobility, and independence when central vision is reduced.
   Mechanism: A team (optometrist/ophthalmologist, occupational therapist, vision rehab therapist) trains magnifier/illumination use, contrast enhancement, eccentric viewing, and task adaptation. Randomized and quality-improvement studies show LVR improves daily function and quality of life. AAO’s PPP endorses referral. American Academy of Ophthalmology+2AAO Journal+2

4. Magnification & electronic aids
   Purpose: Make text and details easier to see.
   Mechanism: Optical magnifiers, high-add spectacles, CCTVs, tablets with zoom, and text-to-speech increase retinal image size and contrast, supporting residual macular/paracentral vision. American Academy of Ophthalmology

5. Contrast & lighting optimization at home/work
   Purpose: Reduce glare and improve task visibility.
   Mechanism: Task lamps, matte surfaces, high-contrast labels, and tinted filters improve signal-to-noise for damaged macula; AAO materials recommend environment changes as part of LVR. vumc.org

6. Reading strategies (eccentric viewing, line guides, large print)
   Purpose: Shift fixation to healthier retina and reduce fatigue.
   Mechanism: Training teaches use of a preferred retinal locus and external guides to stabilize tracking; improves reading speed in macular disease. American Academy of Ophthalmology

7. Genetic counseling (with selective testing)
   Purpose: Clarify inheritance, discuss testing options, and set realistic expectations.
   Mechanism: AAO IRD guidance recommends counseling; testing can confirm PRPH2 or rare CTNNA1 variants but usually does not change BSPMD treatment today; it may inform family planning and trial eligibility. American Academy of Ophthalmology+1

8. Smoking cessation
   Purpose: Protect retinal health.
   Mechanism: Smoking increases oxidative stress and is a major risk factor for AMD progression; although BSPMD differs from AMD, avoiding smoking is a general retinal health recommendation. nei.nih.gov

9. Cardiovascular risk control (BP, lipids, diabetes)
   Purpose: Support ocular perfusion and overall eye health.
   Mechanism: Systemic vascular risk factors worsen many retinal conditions; good control supports retinal metabolism and reduces general ocular risk. (Guidelines extrapolated from vision-rehab/AMD PPPs.) American Academy of Ophthalmology

10. Protective eyewear & UV/blue-light management outdoors
    Purpose: Comfort and glare reduction; theoretical oxidative stress reduction.
    Mechanism: Filters reduce photostress and glare, improving function in macular disease; evidence is stronger for symptom relief than disease modification. American Academy of Ophthalmology

11. Falls-prevention home safety review
    Purpose: Reduce injuries in people with central vision deficits.
    Mechanism: OT-guided home modifications (contrast stair edges, remove hazards) reduce falls; part of vision-rehab PPP workflows. American Academy of Ophthalmology

12. Driving assessment & counseling
    Purpose: Maintain safety and legal compliance.
    Mechanism: Vision specialists assess acuity/field and advise on restrictions or cessation as needed; AAO provides policy resources for low-vision driving considerations. JAMA Network

13. Assistive technology training (OCR apps, screen readers)
    Purpose: Keep reading/work/communication accessible.
    Mechanism: OCR and voice assistants bypass visual demand by converting print to speech; evidence shows improved ADLs in LVR programs. PMC

14. Psychological support & peer groups
    Purpose: Lower anxiety/depression linked to vision loss.
    Mechanism: Counseling and support groups improve coping and quality of life in low vision populations; integrated in PPP recommendations. American Academy of Ophthalmology

15. Education on red-flag symptoms
    Purpose: Speedy action if CNV starts.
    Mechanism: Teaching patients to report sudden distortion, central gray spots, or new bleeding improves time-to-treatment with anti-VEGF. OctClub

16. Workplace/school accommodations
    Purpose: Maintain productivity and learning.
    Mechanism: Enlarged print, flexible lighting, and software zoom; LVR teams provide documentation and training. American Academy of Ophthalmology

17. Exercise & nutrition for general eye health
    Purpose: Support systemic well-being; indirect eye benefits.
    Mechanism: Healthy diet and activity reduce vascular risk; AREDS supplements are not proven for BSPMD specifically (benefit was in intermediate AMD), so discuss expectations. nei.nih.gov

18. Family screening (symptom awareness)
    Purpose: Earlier detection in relatives with autosomal-dominant risk.
    Mechanism: Simple symptom checks and baseline eye exams in adulthood; genetic counseling for interested family members. American Academy of Ophthalmology

19. Referral to retina if imaging shows new activity
    Purpose: Ensure prompt treatment decisions for CNV or fluid.
    Mechanism: Retina specialists deliver intravitreal therapy per FDA-labeled anti-VEGF protocols (for labeled conditions) adapted to CNV from other causes. FDA Access Data

20. Participation in clinical studies (case-by-case)
    Purpose: Access monitoring or investigational care under oversight.
    Mechanism: Some studies enroll inherited macular diseases for imaging/natural history; rare interventional trials exist, but none are approved as disease-modifying therapy for BSPMD. NCBI

Drug treatments

Important safety note: There is no FDA-approved drug that cures BSPMD itself. Drug therapy is used mainly if CNV develops (a treatable complication). The following medicines are FDA-approved for neovascular retinal disease (e.g., wet AMD, diabetic eye disease). Retina specialists often treat CNV from other causes in a similar way, though that specific indication may be off-label—your doctor will explain. Dosing below reflects labeled use for the approved indications; actual regimens are individualized. Always follow your retina specialist’s plan. FDA Access Data+1

1. Ranibizumab (Lucentis®)
   Class: Anti-VEGF-A monoclonal antibody fragment.
   Typical dosage/time: 0.5 mg intravitreal monthly at start; then treat-and-extend or PRN per vision and OCT.
   Purpose: Dry up CNV leakage, improve or maintain vision.
   Mechanism: Neutralizes VEGF-A to reduce abnormal vessel growth/permeability.
   Side effects: Eye pain, floaters, increased IOP; rare endophthalmitis/retinal detachment; systemic arterial thromboembolic events are uncommon. Evidence: pivotal trials and FDA label for wet AMD and other retinal vascular diseases. FDA Access Data+1

2. Aflibercept (Eylea® / Eylea HD®)
   Class: VEGF-trap fusion protein binding VEGF-A, VEGF-B, and PlGF.
   Dosage/time: 2 mg (or 8 mg HD) intravitreal with loading doses then every 4–8–16 weeks depending on indication and response.
   Purpose/mechanism: Potent VEGF pathway blockade to control CNV fluid and stabilize vision.
   Side effects: Similar injection-related risks; label notes precautions for endophthalmitis and IOP spikes. FDA Access Data

3. Faricimab-svoa (Vabysmo®)
   Class: Bispecific antibody targeting VEGF-A and Ang-2.
   Dosage/time: Intravitreal with loading, then up-to-Q16 weeks in approved diseases based on response.
   Purpose/mechanism: Dual-pathway blockade (VEGF-A + Ang-2) improves vessel stability and reduces leakage.
   Side effects: Conjunctival hemorrhage, cataract; standard injection risks and hypersensitivity contraindications. FDA Access Data+1

4. Brolucizumab-dbll (Beovu®)
   Class: Single-chain antibody fragment against VEGF-A.
   Dosage/time: Intravitreal with loading then Q8–12 weeks in labeled uses.
   Purpose/mechanism: High molar dose per injection for drying effect.

5. Pegaptanib sodium (Macugen®)
   Class: Anti-VEGF165 aptamer (older agent).
   Dosage/time: 0.3 mg intravitreal every 6 weeks (historic).
   Purpose/mechanism: Selectively binds VEGF165 isoform to reduce CNV leakage; largely supplanted by newer agents but remains an FDA-approved anti-VEGF for wet AMD.
   Side effects: Similar intravitreal risks; lower efficacy vs newer drugs. FDA Access Data+2FDA Access Data+2

6. Verteporfin (Visudyne®) photodynamic therapy (PDT)
   Class: Photosensitizer used with laser light.
   Dosage/time: IV verteporfin followed by low-power laser to activate; retreatment per leakage.

Dietary molecular supplements

(Evidence for AMD does not equal evidence for BSPMD. Use only with clinician guidance; smokers should avoid beta-carotene.) nei.nih.gov+1

1. Lutein (10 mg/day) – Carotenoid concentrated in macula; may improve macular pigment and visual function in some retinal conditions; AREDS2 used lutein/zeaxanthin instead of beta-carotene. BSPMD-specific benefit unproven. nei.nih.gov

2. Zeaxanthin (2 mg/day in AREDS2; some use 2–4 mg) – Works with lutein to filter blue light/oxidative stress; substitute for beta-carotene in smokers. No direct BSPMD trials. nei.nih.gov

3. Meso-zeaxanthin (varies, often 10 mg in some formulations) – Central macular pigment carotenoid; evidence mainly small studies outside BSPMD. nei.nih.gov

4. Vitamin C (500 mg/day in AREDS) – Antioxidant co-factor; AREDS benefit was in intermediate AMD, not BSPMD. nei.nih.gov

5. Vitamin E (400 IU/day in AREDS) – Antioxidant; same AMD-only evidence caveat. nei.nih.gov

6. Zinc (80 mg zinc oxide/day in AREDS; many use 25–40 mg to reduce side-effects) – Cofactor with antioxidant activity; in AREDS slowed AMD progression; may cause GI upset/copper deficiency—paired with copper (2 mg). nei.nih.gov

7. Omega-3 fatty acids (DHA/EPA, ~1 g/day combined) – NEI notes no added AMD benefit in AREDS2; may support general health; BSPMD benefit unproven. nei.nih.gov

8. Saffron (20–30 mg/day in small AMD trials) – Some small studies showed functional gains in AMD; insufficient data for BSPMD—discuss with your doctor. nei.nih.gov

9. Coenzyme Q10/ubiquinone (varied doses) – Antioxidant/mitochondrial cofactor; evidence in macular dystrophies is limited. nei.nih.gov

10. Resveratrol (e.g., 150–250 mg/day in supplements) – Polyphenol with anti-oxidative/anti-angiogenic signals in lab models; clinical retinal benefits remain uncertain. nei.nih.gov

Immunity-booster / regenerative / stem-cell drugs

Transparent guidance: There are no FDA-approved “immunity boosters,” regenerative drugs, or stem-cell products proven to treat BSPMD. Unregulated stem-cell injections into the eye have caused severe, permanent harm. If you see offers online, avoid them. Research is ongoing in other retinal diseases (for example, RPE cell therapy and gene therapy for RPE65-related disease), but nothing is approved for BSPMD today. Focus on safe, evidence-based monitoring, vision rehabilitation, and treating CNV if it appears. American Academy of Ophthalmology

---

Surgeries (what they are and why done)

1. Intravitreal injection procedures (sterile, office-based) – Not “surgery” in the operating room but a minor sterile procedure to deliver anti-VEGF directly into the eye to treat CNV; done because medicine must reach the retina. FDA Access Data+1

2. Photodynamic therapy (PDT) with verteporfin – IV drug plus laser to shut down leaking CNV in specific patterns; considered when appropriate to lesion type or when anti-VEGF is contraindicated/insufficient. FDA Access Data

3. Pars plana vitrectomy (rare in BSPMD) – Considered only for complications like non-clearing vitreous hemorrhage or traction unrelated to the dystrophy itself. American Academy of Ophthalmology

4. Cataract surgery (if visually significant cataract coexists) – Improves blur caused by lens opacity; does not treat BSPMD but may improve overall function. AAO Journal

5. Historical macular translocation/submacular surgery – Now largely obsolete for CNV due to risks and the success of anti-VEGF therapy; included for completeness. FDA Access Data

Preventions

While you cannot “prevent” the underlying gene change, you can lower general retinal stress and protect remaining vision:

1. Don’t smoke; avoid second-hand smoke. nei.nih.gov

2. Control blood pressure, lipids, and diabetes with your doctor. American Academy of Ophthalmology

3. Use sunglasses/filters outdoors to reduce glare/photostress. American Academy of Ophthalmology

4. Eat a balanced diet rich in leafy greens, fruit, and fish (for overall health). nei.nih.gov

5. Keep regular retina check-ups and home Amsler testing. NCBI

6. Act quickly if lines look wavy or a dark spot appears. OctClub

7. Organize good lighting and high-contrast labels at home. vumc.org

8. Use magnifiers and assistive tech early; practice eccentric viewing. American Academy of Ophthalmology

9. Stay physically active and maintain a healthy weight. American Academy of Ophthalmology

10. Consider genetic counseling for family planning and education. American Academy of Ophthalmology

When to see a doctor (simple triggers)

See a retina specialist immediately if you notice sudden distortion (wavy lines), a new dark or gray spot in central vision, new floaters/flashes, eye pain, or any bleeding in the eye. These can signal CNV, retinal tear, or post-injection infection, and quick treatment protects vision. Keep routine follow-up even if you feel fine; slow changes can be missed without imaging. OctClub+1

What to eat and what to avoid

1. Eat: Leafy greens (spinach, kale) for lutein/zeaxanthin—general macular health; BSPMD benefit unproven. nei.nih.gov

2. Eat: Oily fish (salmon, sardines) as part of a heart-healthy diet. nei.nih.gov

3. Eat: Colorful fruits/vegetables for antioxidants. nei.nih.gov

4. Eat: Nuts/legumes/whole grains to support vascular health. American Academy of Ophthalmology

5. Consider (with doctor): AREDS2-style supplement if you also have intermediate AMD—not for BSPMD specifically. nei.nih.gov

6. Avoid/limit: Smoking and secondhand smoke. nei.nih.gov

7. Avoid: Unproven “eye cure” supplements or stem-cell clinics. American Academy of Ophthalmology

8. Limit: Highly processed foods; aim for heart-healthy patterns. American Academy of Ophthalmology

9. Hydrate: Adequate water for general health. American Academy of Ophthalmology

10. Check labels: If using zinc, ensure copper is included to avoid deficiency. nei.nih.gov

FAQs

1) Is BSPMD the same as AMD?
No. BSPMD is an inherited pattern dystrophy (often PRPH2-related); AMD is age-related and multifactorial. They can look similar, so imaging is important. EyeWiki

2) Will I go blind?
Most people keep usable vision for many years. A minority develop CNV that needs prompt treatment to protect sight. NCBI

3) What gene is involved?
Often PRPH2; rarely CTNNA1 and others. Genetic counseling helps families understand risk. PMC+1

4) Is there a cure?
No cure today. Care focuses on monitoring, vision-rehab strategies, and treating CNV if it appears. NCBI

5) Do AREDS vitamins help?
AREDS2 helps some people with intermediate AMD but is not proven for BSPMD. Discuss with your doctor. nei.nih.gov

6) Can anti-VEGF shots help me?
Only if you develop CNV. They dry leakage and often improve or stabilize vision; schedules vary by drug and response. FDA Access Data+1

7) Are there risks to injections?
Yes—rare infection (endophthalmitis), pressure rise, inflammation; labels list risks and safety steps. FDA Access Data+1

8) Should my family be checked?
Yes, because inheritance is usually autosomal dominant. Family members can have baseline eye exams and consider counseling/testing. American Academy of Ophthalmology

9) What tests confirm BSPMD?
Dilated exam, OCT, fundus autofluorescence, sometimes fluorescein/ICG angiography; genetic testing in selected cases. NCBI

10) How often are check-ups?
Commonly every 6–12 months, sooner with any new symptoms; your doctor will tailor the plan. NCBI

11) Can glasses fix it?
Glasses fix refractive error, not macular damage. Low-vision tools and training help you use remaining vision better. American Academy of Ophthalmology

12) Are stem-cell or “regenerative” shots available?
No approved stem-cell treatments for BSPMD. Avoid clinics offering unproven injections. American Academy of Ophthalmology

13) Can I keep working or studying?
Yes—with lighting, magnification, software, and accommodations guided by a vision-rehab team. American Academy of Ophthalmology

14) Can BSPMD progress slowly?
Yes—many cases are slowly progressive. That’s why regular imaging and home Amsler checks matter. EyeWiki

15) Where can I learn more and find rehab help?
AAO vision rehabilitation resources and local LVR programs are good starting points. American Academy of Ophthalmology
