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:
Classic butterfly type – 3–5 wing-like arms of pigment centered on the fovea. EyeWiki
Butterfly with vitelliform material – butterfly arms with small egg-yolk-like deposits. NCBI
Butterfly variant linked to specific PRPH2 mutations – similar look, variable severity among families. PMC+1
Butterfly-like pattern from other genes (rarer) – for example CTNNA1 variants can produce a butterfly pattern that mimics PRPH2 disease. PMC
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:
Autosomal dominant inheritance (one affected parent can pass it on). NCBI
PRPH2 (RDS) gene variants – the most frequent cause; peripherin-2 supports photoreceptor outer segments. JAMA Network+1
Dominant-negative PRPH2 effects – mutant protein interferes with normal peripherin-2. faseb.onlinelibrary.wiley.com
PRPH2 C213 variants – specific cysteine changes have been tied to a butterfly phenotype. faseb.onlinelibrary.wiley.com
Digenic interaction (PRPH2 with ROM1) – rare double-gene mechanism worsening outer-segment structure. PMC
CTNNA1 variants – can produce butterfly-like macular lesions. PMC
ABCA4 variants – occasionally yield pattern dystrophy-like maculas overlapping with Stargardt spectrum. NCBI
BEST1 variants – in some families, adult-onset vitelliform/pattern features overlap. NCBI

RPE-photoreceptor interface dysfunction – structural and functional coupling fails. NCBI
Visual cycle by-product overload (A2E and related) – contributes to FAF signal. ScienceDirect
Rare systemic associations (e.g., myotonic dystrophy) – likely shared retinal vulnerability. JSTAGE
Penetrance and variable expressivity – some carriers have few signs; others have clear butterfly wings. PMC
Environmental contributors (possible) – factors like smoking/oxidative stress are suspected modifiers, though genetics dominates. (Review-based.) NCBI
Common symptoms
No symptoms at first – many people are found on routine exams. EyeWiki
Blurred central vision – letters look less sharp. NCBI
Metamorphopsia – straight lines look wavy or bent. journalor.com
Reading difficulty – words fade or break, especially in dim light. NCBI
Small central or paracentral blank spots (scotomas). disorders.eyes.arizona.edu
Glare sensitivity – bright light bothers the eyes. NCBI
Slow dark adaptation – takes longer to see after lights go off. NCBI
Color vision changes – colors look dull or off. NCBI
Photopsias – brief flashes or sparkles. NCBI
Eye strain with near work – holding text closer. NCBI
Headaches from visual effort – due to strain, not the retina itself. (Clinical reviews.) NCBI
Difficulty seeing faces – central blur affects fine detail. NCBI
Stable for years – many cases change slowly. EyeWiki
Sudden drop if CNV develops – new vessels leak and harm central vision. NCBI
Both eyes involved – usually similar patterns in both eyes. EyeWiki
Diagnostic tests
A) Physical exam (in-clinic checks)
Best-corrected visual acuity – letter chart measures central clarity; tracks change over time. NCBI
Pupil exam – rules out optic nerve problems; usually normal in this disease. NCBI
Slit-lamp exam with dilated funduscopy – doctor looks at the macula; sees the butterfly pigment arms. EyeWiki
Intraocular pressure and lens check – screens for other issues that can affect vision. NCBI
B) Manual/bedside vision tests
Amsler grid – patient looks at a square grid; wavy or missing boxes suggest macular change. NCBI
Near-reading card – checks functional reading vision at a set distance. NCBI
Color vision plates – detects subtle color loss common in macular disease. NCBI
Contrast sensitivity test – measures how well faint letters or low-contrast patterns are seen. NCBI
C) Laboratory & pathological (molecular) tests
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
Sanger confirmation – validates a panel finding in PRPH2 or other genes. PMC
Segregation testing in relatives – checks if the variant tracks with the disease in the family. PMC
Genetic counseling session – explains inheritance, risks to children, and testing choices. NCBI
(Rare) Histopathology – research reports show lipofuscin/RPE changes consistent with the clinical picture. Not done in routine care. JAMA Network
D) Electrodiagnostic tests
Full-field electroretinogram (ffERG) – often normal or mildly reduced because the disease is macula-focused; helps exclude diffuse retinal dystrophies. NCBI
Multifocal ERG (mfERG) – maps central retina function; shows depressed responses in the macular area. NCBI
Electro-oculogram (EOG) – tests RPE function; may be near normal or mildly abnormal. NCBI
Pattern ERG (pERG) – evaluates macular ganglion/central function; can support macular dysfunction. NCBI
E) Imaging tests
Fundus photography – documents the butterfly shape over time. EyeWiki
Fundus autofluorescence (FAF) – highlights lipofuscin; shows bright/dark butterfly wings and helps watch for spread or atrophy. ScienceDirect
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)
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+1Amsler 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. NCBILow-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+2Magnification & 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 OphthalmologyContrast & 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.orgReading 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 OphthalmologyGenetic 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+1Smoking 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.govCardiovascular 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 OphthalmologyProtective 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 OphthalmologyFalls-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 OphthalmologyDriving 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 NetworkAssistive 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. PMCPsychological 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 OphthalmologyEducation 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. OctClubWorkplace/school accommodations
Purpose: Maintain productivity and learning.
Mechanism: Enlarged print, flexible lighting, and software zoom; LVR teams provide documentation and training. American Academy of OphthalmologyExercise & 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.govFamily 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 OphthalmologyReferral 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 DataParticipation 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

Sometimes considered in special CNV scenarios. FDA Access Data+2FDA Access Data+2Topical povidone-iodine (procedure antisepsis) – reduces endophthalmitis risk before injections. FDA Access Data
Topical anesthetics for injection comfort – lidocaine/tetracaine per label; procedural adjunct. FDA Access Data
Topical antibiotic use is not routinely recommended post-injection—practice has shifted; sterile technique is key. FDA Access Data
Intraocular pressure management (short-acting drops as needed) after injections in susceptible eyes; clinician-directed. FDA Access Data
Corticosteroid avoidance unless indicated for other retinal diseases; steroids do not treat BSPMD and can raise IOP/cataract risk. NCBI

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
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
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
Meso-zeaxanthin (varies, often 10 mg in some formulations) – Central macular pigment carotenoid; evidence mainly small studies outside BSPMD. nei.nih.gov
Vitamin C (500 mg/day in AREDS) – Antioxidant co-factor; AREDS benefit was in intermediate AMD, not BSPMD. nei.nih.gov
Vitamin E (400 IU/day in AREDS) – Antioxidant; same AMD-only evidence caveat. nei.nih.gov
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
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
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
Coenzyme Q10/ubiquinone (varied doses) – Antioxidant/mitochondrial cofactor; evidence in macular dystrophies is limited. nei.nih.gov
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)
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
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
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
Cataract surgery (if visually significant cataract coexists) – Improves blur caused by lens opacity; does not treat BSPMD but may improve overall function. AAO Journal
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:
Don’t smoke; avoid second-hand smoke. nei.nih.gov
Control blood pressure, lipids, and diabetes with your doctor. American Academy of Ophthalmology
Use sunglasses/filters outdoors to reduce glare/photostress. American Academy of Ophthalmology
Eat a balanced diet rich in leafy greens, fruit, and fish (for overall health). nei.nih.gov
Keep regular retina check-ups and home Amsler testing. NCBI
Act quickly if lines look wavy or a dark spot appears. OctClub
Organize good lighting and high-contrast labels at home. vumc.org
Use magnifiers and assistive tech early; practice eccentric viewing. American Academy of Ophthalmology
Stay physically active and maintain a healthy weight. American Academy of Ophthalmology
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
Eat: Leafy greens (spinach, kale) for lutein/zeaxanthin—general macular health; BSPMD benefit unproven. nei.nih.gov
Eat: Oily fish (salmon, sardines) as part of a heart-healthy diet. nei.nih.gov
Eat: Colorful fruits/vegetables for antioxidants. nei.nih.gov
Eat: Nuts/legumes/whole grains to support vascular health. American Academy of Ophthalmology
Consider (with doctor): AREDS2-style supplement if you also have intermediate AMD—not for BSPMD specifically. nei.nih.gov
Avoid/limit: Smoking and secondhand smoke. nei.nih.gov
Avoid: Unproven “eye cure” supplements or stem-cell clinics. American Academy of Ophthalmology
Limit: Highly processed foods; aim for heart-healthy patterns. American Academy of Ophthalmology
Hydrate: Adequate water for general health. American Academy of Ophthalmology
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
