Blepharophimosis, Ptosis, and Epicanthus Inversus Syndrome (BPES)

BPES is a birth condition where the openings of both eyelids are too small (blepharophimosis), the upper eyelids droop (ptosis), the inner eyelid skin folds run upside-down toward the nose (epicanthus inversus), and the inner corners of the eyes sit too far apart (telecanthus). These features can partially block vision, raise the risk of amblyopia, and cause eye surface dryness or irritation because the lids don’t move normally. BPES comes in two main forms: Type II affects only the eyelids; Type I also causes ovarian insufficiency in many females, which can lead to delayed puberty or infertility if untreated. BPES is usually inherited in an autosomal dominant way but may appear first in a family. (Evidence: AAO Preferred Practice Patterns on ptosis/amblyopia; Orphanet & GeneReviews summaries on BPES and FOXL2.)

Four main eye features usually appear together:

• Blepharophimosis: the eye openings are shorter and narrower than usual.

• Ptosis: the upper eyelids droop.

• Epicanthus inversus: a skin fold runs upward from the lower eyelid to the inner corner of the eye.

• Telecanthus: the inner corners of the eyes look farther apart than normal.

Most children with BPES have these features in both eyes. The condition is usually caused by a change (mutation) in a gene called FOXL2. This gene guides eyelid development before birth and also helps the ovaries work in females. Testing the FOXL2 gene confirms the diagnosis? in most families. NCBI+2MedlinePlus+2

Other (Another) Names

• BPES

• Blepharophimosis syndrome

• Blepharophimosis–ptosis–epicanthus inversus

• FOXL2-related BPES

• Blepharophimosis–ptosis–telecanthus with epicanthus inversus (descriptive) NCBI+1

Types

BPES has two main types. The eyelid findings are similar in both.

1. Type I: eyelid changes plus a risk in females for primary ovarian insufficiency (POI)—periods become infrequent and may stop before age 40, and fertility can be reduced. The age when this starts can vary widely. NCBI+2MedlinePlus+2

2. Type II: eyelid changes only, without ovarian problems. MedlinePlus

The exact gene change does not always predict whether a girl or woman will have ovarian problems. Because of this, girls and women with BPES should get counseling and ovarian reserve checks during adolescence or early adulthood. MDPI

Causes

BPES is almost always genetic and most often autosomal dominant (one changed copy of FOXL2 is enough). Below are simple explanations of known, common, and plausible mechanisms—all focused on how the FOXL2 gene can be altered or how its effect can be reduced.

1. FOXL2 haploinsufficiency: one working copy is not enough, so eyelids do not form normally. NCBI

2. Polyalanine (poly-Ala) expansion in FOXL2: the gene gains extra “alanine” building blocks, making the protein clump or mis-localize; often linked with Type II. ScienceDirect+1

3. Missense variant in the forkhead (DNA-binding) domain: a single letter change weakens FOXL2’s grip on DNA targets. NCBI

4. Nonsense variant: a “stop” signal appears too early; the protein is cut short and cannot work. NCBI

5. Frameshift variant: letters are inserted or deleted, shifting the reading frame and damaging the protein. ScienceDirect

6. Splice-site variant: instructions for cutting and joining the gene’s pieces are altered; abnormal message is made. NCBI

7. Whole-gene deletion (copy-number loss): the entire FOXL2 gene is missing on one chromosome. NCBI

8. Intragenic deletion/duplication: only part of the gene is missing or copied; the protein cannot function correctly. NCBI

9. 3q23 microdeletion including FOXL2: a small missing piece of chromosome 3 removes FOXL2 and nearby elements. NCBI

10. Chromosomal translocation disrupting FOXL2 or its control region: a break repositions the gene so it cannot turn on correctly in eyelid tissues. NCBI

11. Regulatory-domain variant near FOXL2: the gene’s “switches” are mutated; the eyelid program is turned down. NCBI

12. Position effect (long-range control lost): a distant enhancer is separated from FOXL2 by a rearrangement. NCBI

13. Mosaic FOXL2 variant: only some cells carry the mutation; the appearance can vary between family members. NCBI

14. De novo variant: the change happens for the first time in the child (not inherited from parents). NCBI

15. Gonadal mosaicism in a parent: a parent’s egg/sperm carries the change even if their body cells test negative. NCBI

16. Polyalanine expansion with recessive expression (rare reports): two altered copies or special contexts can change the pattern of inheritance. PubMed

17. FOXL2 variants that mainly affect ovarian targets: same eyelid features, plus higher risk of ovarian insufficiency (Type I). OUP Academic+1

18. Unknown FOXL2-adjacent enhancer defects: when typical testing is negative, missing deep regulatory elements may be the cause. NCBI

19. Contiguous-gene deletions (“BPES-plus”): larger 3q23 deletions can add other features beyond the eyelids. Orpha.net

20. Extremely rare phenocopies: different genes or syndromes can mimic BPES externally, but true BPES is FOXL2-related. Genetic testing separates them. NCBI

Symptoms and Signs

1. Narrow eye openings (blepharophimosis): the eyelid openings are short and tight from side to side; eyes may look “smaller.” NCBI

2. Droopy upper eyelids (ptosis): lids hang low and can cover the pupil; a chin-up head posture is common to see better. NCBI

3. Upward fold at the inner corner (epicanthus inversus): a skin fold climbs from below, partly covering the inner eye corner. Orpha.net

4. Wide-appearing inner eye corners (telecanthus): distance between inner canthi looks increased even if pupils are centered. NCBI

5. Amblyopia (“lazy eye” risk): low lid height and poor eyelid opening can blur images and block normal vision development if untreated. NCBI

6. Refractive errors (needing glasses): farsightedness, astigmatism, or other focusing problems can occur with the eyelid shape. NCBI

7. Strabismus (eye misalignment): crossed or drifting eyes may develop due to vision imbalance. NCBI

8. Head tilt or chin-up posture: a child lifts the chin to see under the droopy lids; this is a classic compensating habit. NCBI

9. Frequent brow lifting: the child raises the eyebrows to help lift the eyelids. NCBI

10. Tearing or irritation: lashes or tight eyelid skin can rub on the eye surface; dry spots or watering may occur. NCBI

11. Light sensitivity (photophobia): the eye surface can be dry or irregular, making bright light uncomfortable. NCBI

12. Cosmetic concern and social stress: the visible eyelid differences can affect confidence; support helps. NCBI

13. Normal eye structures otherwise: the eye itself is often healthy; problems come mainly from lids blocking vision. NCBI

14. Female reproductive issues (Type I only): periods may become irregular or stop early; getting pregnant can be hard without help. MedlinePlus+1

15. Family history with similar eyelids: one parent or several relatives may have the same features because inheritance is often dominant. MedlinePlus

Diagnostic Tests (with simple explanations)

A) Physical examination (at the clinic)

1. Full face and eyelid inspection: the doctor confirms the four hallmark features and checks both eyes. This clinical pattern strongly suggests BPES. NCBI

2. Palpebral fissure measurements: measuring the horizontal and vertical opening shows how narrow each eyelid gap is. NCBI

3. Margin–reflex distance (MRD1) and ptosis grading: shows how much the upper lid covers the pupil to plan treatment. NCBI

4. Levator function test: the examiner measures how well the eyelid-lifting muscle works; this guides surgical choice. NCBI

5. Inner canthal distance (ICD) and telecanthus check: calipers measure the inner eye corner spacing to document severity. NCBI

6. Visual acuity by age level: age-appropriate eye charts or picture tests check how well each eye sees. NCBI

B) Manual/bedside eye tests

7. Cover–uncover and alternate cover tests: these simple alignment tests look for strabismus that can worsen amblyopia. NCBI

8. Hirschberg corneal light reflex: a penlight reflection on the corneas detects small misalignments quickly. NCBI

9. Pupillary exam and motility check: rules out nerve palsy and confirms normal eye movements behind the eyelids. NCBI

10. Eyelid distraction and snap-back tests: look for eyelid laxity or in-turning that might irritate the eye surface. NCBI

C) Laboratory and pathological (including genetics and hormones)

11. FOXL2 sequencing: reads the gene “letters” to find missense, nonsense, or frameshift variants. This is the core confirmation test. NCBI

12. Deletion/duplication analysis (e.g., MLPA or CNV testing): detects whole-gene or partial gene losses/gains not seen on sequencing. NCBI

13. Chromosomal microarray (CMA): looks for 3q23 microdeletions or other copy-number changes around FOXL2. NCBI

14. Karyotype (if a rearrangement is suspected): finds large translocations or inversions disrupting the gene or its controls. NCBI

15. Female hormone tests (for Type I risk): FSH, LH, estradiol, and AMH help assess ovarian reserve and early ovarian insufficiency. MDPI

D) Electrodiagnostic (used selectively)

16. Visual evoked potentials (VEP): checks the visual pathway if severe ptosis or amblyopia makes vision assessment unclear. NCBI

17. Electroretinogram (ERG) (rarely needed): confirms retinal function when cooperation is limited or findings are mixed; the retina is usually normal in BPES. NCBI

E) Imaging tests

18. External ophthalmic photography or 3-D facial imaging: documents baseline facial and eyelid measurements before and after surgery. NCBI

19. Orbital/craniofacial CT (selected surgical planning): helps plan bone or tendon? procedures when anatomy is unusual. Use only when it changes decisions. NCBI

20. Pelvic ultrasound?/MRI in females (when indicated): reviews ovarian size and follicle counts in those with suspected Type I or fertility concerns. MDPI

Non-pharmacological treatments (therapies & others)

Note: These measures support vision, safety, and comfort. They do not “cure” BPES but reduce complications (like amblyopia and dry eye) and prepare for/maintain surgical results.

1. Regular pediatric-ophthalmology follow-up – Frequent eye checks watch for amblyopia, refractive error, and corneal exposure. Early detection prevents long-term vision loss. Genetic counseling is also planned from the start. NCBI

2. Amblyopia therapy (patching) – If one eye becomes weaker, covering the stronger eye for set hours trains the weak eye. This is standard pediatric care to protect vision development when eyelids block sight. NCBI

3. Glasses for refractive error – Correcting astigmatism or farsightedness helps focus and reduces the amblyopia risk while waiting for surgery. NCBI

4. Timing plan for surgery – If pupils are clear, surgeons often schedule repair at 3–5 years; if the pupil is covered or lid opening is very small, earlier surgery is considered to protect vision. Families receive a staged plan. NCBI+1

5. Lid hygiene & warm compresses – Gentle lid cleaning keeps lashes and margins healthy, lowering irritation and helping the eye surface before and after operations. EyeWiki

6. Environmental eye care – Avoid smoke and wind; use humidifiers; take screen breaks. These steps reduce evaporation and discomfort when blinking is limited by anatomy. PMC

7. Daytime blink training & safe taping at night (clinician-guided) – Teaching mindful blinking and, in select cases, protective taping at night can reduce exposure symptoms pending surgery. This must be taught by clinicians to avoid harm. EyeWiki

8.

10. School accommodations – Preferential seating and larger print help children with limited vertical lid opening until surgery improves the visual field. NCBI

11. Care team coordination – Multidisciplinary planning (pediatric ophthalmology, oculoplastic surgery, genetics, sometimes endocrinology) ensures safe anesthesia timing and follow-up for girls at risk of ovarian issues. NCBI

12. Genetic counseling – Families learn inheritance patterns (often autosomal dominant), recurrence risk, and options such as prenatal or preimplantation testing. NCBI

13. Fertility counseling for females (Type I) – Women with Type I may plan earlier fertility evaluation and discuss egg preservation or assisted reproduction options. Frontiers

14. Psychosocial support – Counseling can help with appearance-related stress before reconstructive surgery; this improves adherence to care plans. National Organization for Rare Disorders

15. Post-op wound care education – Families learn how to keep incisions clean, avoid rubbing, and recognize signs of infection? after canthoplasty or ptosis repair. EyeWiki

16. Amblyopia alternatives (penalization planning) – If patching fails, clinicians may consider alternative penalization strategies; the concept remains to balance vision between eyes under supervision. NCBI

17. Low-vision support if needed – Rarely required long-term, but temporary aids can help school performance pre-repair. NCBI

18. Endocrine screening? when indicated – Selected patients receive endocrine review (e.g., for suspected hypopituitarism), guided by symptoms and genetics. Karger Publishers

19. Surface-healing biomaterials (surgeon-directed) – In select ocular surface problems, amniotic membrane can promote healing because it reduces infection?, or irritation, often causing pain?, swelling?, heat, or redness. সহজ বাংলা: শরীরের প্রদাহ; ব্যথা, ফোলা বা লালভাব হতে পারে।" data-rx-term="inflammation" data-rx-definition="Inflammation is the body’s response to injury, infection, or irritation, often causing pain, swelling, heat, or redness. সহজ বাংলা: শরীরের প্রদাহ; ব্যথা, ফোলা বা লালভাব হতে পারে।">inflammation? and scarring; used by specialists when indicated. American Academy of Ophthalmology+1

20. Family education on red flags – Families learn to watch for a chin-up head posture, eye misalignment, constant tearing, or frequent tripping—all signs the droop is limiting vision and needs earlier action. NCBI

Drug treatments

Important: No medicine fixes the eyelid shape in congenital? BPES.

Dietary molecular supplements

No supplement treats BPES anatomy. These nutrients support overall eye surface and ocular health; use only with clinician guidance, especially in children/pregnancy.

1. Omega-3 fatty acids (EPA/DHA) – May modestly improve some dry eye signs but symptom benefits are mixed across trials; still reasonable for diet quality (fish, nuts). Typical supplemental doses vary (e.g., 1–2 g/day EPA+DHA in adults under medical advice). Cochrane Library+1

2. Lutein – A carotenoid concentrated in the retina; best obtained from leafy greens/eggs. Evidence is strongest in AMD, not BPES; still part of eye-healthy diets. (Common study doses: 10–20 mg/day in adults.) JAMA Network

3. Zeaxanthin – Works with lutein as macular pigment; again AMD-focused data (AREDS2), not BPES. Food-first is preferred. National Eye Institute

4. Vitamin A (with caution) – Essential for ocular surface and night vision; deficiency causes xerophthalmia and corneal problems. Avoid excess (toxicity). Dose needs vary by age; follow NIH guidance. Office of Dietary Supplements+1

5. Vitamin C – Antioxidant supportive of collagen and wound repair; part of AREDS-style formulations (for AMD), not specific to BPES. Use balanced diet. National Eye Institute

6. Vitamin E – Antioxidant included in AREDS/AREDS2 combinations; balance benefits with general safety guidance. National Eye Institute

7. Zinc (± copper) – Component of AREDS supplements; high-dose zinc should be supervised and paired with copper to prevent deficiency. National Eye Institute

8. Hydration & electrolytes – Adequate fluid intake supports tear film; simple but important for comfort when blink is reduced. (General ocular surface care principles from clinical dry-eye literature.) PMC

9. Dietary pattern (Mediterranean-style) – Emphasizes fish, vegetables, fruits, legumes, whole grains, and olive oil—supports systemic and ocular health. (General evidence base; complements omega-3/antioxidant guidance.) PubMed

10. Avoid megadosing & “miracle” eye pills – Supplements can interact with medicines or be unsafe in kids/pregnancy; use clinician-approved products only. (NIH ODS general guidance.) Office of Dietary Supplements

Immunity booster / regenerative / stem-cell” drugs

There are no FDA-approved stem-cell or gene-therapy drugs for BPES. Regenerative tools sometimes used for ocular surface disease (not to change eyelid anatomy) include:

1. Amniotic membrane graft (surgical/biologic tissue, not a pill) – Applied in theater to help healing and reduce inflammation/scarring after ocular surface injury or select reconstructions. American Academy of Ophthalmology+1

2. Autologous serum eye drops (specialist compounded) – Provide growth factors to support corneal epithelium in severe surface disease; used under strict protocols. mcgs.bcbsfl.com

3. Platelet-rich plasma eye drops (investigational/compounded) – Similar rationale to serum; small studies support epithelial healing in select cases. annalsoftransplantation.com

4. Limbal stem-cell transplantation (surgery) – For true limbal stem-cell deficiency (not typical in BPES); restores ocular surface in severe cases from other causes. mcgs.bcbsfl.com

5. Future FOXL2-targeted gene therapy (research stage) – Laboratory work continues clarifying FOXL2 variants; no approved therapy yet. BioMed Central+1

6. Biologic anti-inflammatories for dry eye (e.g., cyclosporine) – Already listed in drugs section; considered disease-modifying for dry eye, not BPES anatomy. FDA Access Data

Surgeries (procedure & why it’s done)

1. Medial canthoplasty (with Z-plasties) – Reconstructs the inner eyelid angle to correct epicanthus inversus and telecanthus, widening the horizontal palpebral fissure. It improves eye appearance and sets the stage for accurate ptosis repair. Often performed first if staged. American Academy of Ophthalmology

2. Ptosis repair – frontalis (tarso-frontal) sling – Connects upper lid to forehead muscle to lift lids when levator function is poor, opening the visual axis and reducing chin-up head posture that can cause neck strain. American Academy of Ophthalmology

3. Ptosis repair – levator resection/advancement – If levator muscle has enough function, tightening it lifts the lid. This can be done in the same sitting or after medial canthoplasty, depending on surgeon plan. EyeWiki

4. Lateral canthoplasty/canthopexy (as needed) – Adjusts outer eyelid angle and supports lid tension to balance the new shape after medial work. American Academy of Ophthalmology

5. One-stage vs two-stage strategy – Some centers do both medial canthoplasty and ptosis repair together; others stage them. Timing is based on visual axis safety and eyelid measurements; outcomes are generally good when thoughtfully selected. Nature+1

Preventions (practical)

1. Early diagnosis and scheduled follow-ups prevent amblyopia. NCBI

2. Treat refractive errors early to balance vision. NCBI

3. Start amblyopia therapy promptly if needed. NCBI

4. Plan surgery at the right time (earlier if pupils are blocked). NCBI

5. Protect the ocular surface (humidity, breaks, sunglasses). PMC

6. Avoid eye rubbing (manage allergies). FDA Access Data

7. Teach wound-care rules after surgery to avoid infections. FDA Access Data

8. Genetic counseling for family planning and recurrence risk. NCBI

9. Fertility counseling for Type I females (consider earlier evaluation). Frontiers

10. Consider endocrine review when symptoms suggest pituitary issues. Karger Publishers

When to see doctors (now vs routine)

• Immediately/soon: the pupil is partly/fully covered, child tilts head back (chin-up), frequent trips/falls, constant tearing or discharge, redness/pain, or new eye misalignment. These are warning signs of visual axis obstruction or infection. NCBI

• Routine but timely: planning first surgery, glasses not helping at school, or questions about patches/therapies. NCBI

• For females with Type I: irregular periods, hot flashes, or trouble conceiving—seek gyne/endocrine review for possible primary ovarian insufficiency. NCBI

What to eat & what to avoid

• Eat: fish (omega-3s), leafy greens and eggs (lutein/zeaxanthin), colorful fruits/veg (vitamins C/A), nuts/legumes/whole grains (zinc and antioxidants). These support general eye health and surface comfort. PubMed+1

• Avoid: smoking and smoky environments; they worsen dry eye and healing. PMC

• Be careful with supplements: vitamin A is essential but can be toxic if overused—use clinician guidance, especially in children/pregnancy. Office of Dietary Supplements+1

FAQs

1) Can BPES go away without surgery?
No. Eyelid shape is structural. Surgery corrects anatomy; non-surgical care protects the eye until then. NCBI

2) Is BPES inherited?
Often yes (frequently autosomal dominant), but new mutations can occur. Genetic testing confirms and guides family planning. NCBI

3) What is the difference between Type I and Type II?
Type I adds primary ovarian insufficiency in females; Type II does not. NCBI

4) When is surgery done?
If vision is safe, many centers operate at 3–5 years; if the pupil is blocked, earlier surgery is chosen to prevent amblyopia. NCBI

5) One-stage or two-stage surgery—what’s better?
Both can work. Surgeons choose based on eyelid measurements and safety; outcomes are good with proper selection. Nature

6) Will eye drops fix congenital ptosis?
No. Drops can soothe the surface or treat infection/allergy but do not change eyelid structure. (Oxymetazoline 0.1% is approved for acquired ptosis in adults.) FDA Access Data

7) Can BPES cause blindness?
Untreated obstruction can cause amblyopia (lazy eye). Timely glasses, patching, and surgery prevent permanent loss. NCBI

8) Do girls with BPES always have fertility problems?
No. Only Type I carries this risk, and even then, results vary. Early counseling helps. NCBI+1

9) Are there gene or stem-cell cures yet?
No approved therapies. Research is ongoing into FOXL2 biology; current care focuses on surgery and supportive eye care. BioMed Central

10) Will my child need repeat surgeries?
Sometimes, as the face grows or if ptosis is very severe; follow-up guides decisions. Nature

11) Do I need to worry about the cornea drying?
Some patients have exposure or reduced blink; surface protection (environmental steps, clinician-guided lubricants) helps. PMC

12) Is amniotic membrane used in BPES?
Not for eyelid shape, but surgeons may use it for ocular surface healing when indicated. American Academy of Ophthalmology

13) Can omega-3s or vitamins fix BPES?
No. They may support overall eye health; they do not change eyelid anatomy. Food-first is best; supplements only under medical advice. Cochrane Library+1

14) Are allergy drops helpful?
Yes—by reducing itch and rubbing that can irritate lids and wounds. Use FDA-labeled antihistamine/mast-cell stabilizers as directed. FDA Access Data

15) Why is spacing eye drops important?
Labels advise 5–15 minutes between drops to prevent washout and ensure each medicine works as intended. FDA Access Data+1
