Short answer · Medically reviewed summary · Last updated: 2026-05-08
Blepharophimosis Ptosis Epicanthus Inversus Syndrome (BPES) is a rare genetic condition characterized by four specific eyelid abnormalities present from birth, which can be diagnosed through clinical examination and genetic testing for the FOXL2 gene. If you suspect you or a loved one has BPES, look for the combination of narrow horizontal eyelid openings, drooping eyelids, skin folds near the inner eye corners, and an outward-turned lower eyelid. What are the primary clinical signs of BPES? Individuals with Blepharophimosis Ptosis Epicanthus Inversus Syndrome typically display a distinct facial appearance due to the following four features: Blepharophimosis: A narrowing of the horizontal eye opening. Ptosis: Drooping of the upper eyelids that may obstruct vision. Epicanthus inversus: A vertical fold of skin starting from the lower eyelid and extending upward. Telecanthus: An increased distance between the inner corners of the eyes. How is BPES diagnosed and what tests should I ask for? Diagnosis of BPES is primarily clinical, meaning a doctor identifies the condition through a physical examination of the eyes.
How do I know if I have BPES - Blepharophimosis Ptosis Epicanthus Inversus Syndrome?
Could you have BPES - Blepharophimosis Ptosis Epicanthus Inversus Syndrome? Early signs that prompted real patients to seek diagnosis, plus medically reviewed guidance.
Blepharophimosis Ptosis Epicanthus Inversus Syndrome (BPES) is a rare genetic condition characterized by four specific eyelid abnormalities present from birth, which can be diagnosed through clinical examination and genetic testing for the FOXL2 gene. If you suspect you or a loved one has BPES, look for the combination of narrow horizontal eyelid openings, drooping eyelids, skin folds near the inner eye corners, and an outward-turned lower eyelid.
What are the primary clinical signs of BPES?
Individuals with Blepharophimosis Ptosis Epicanthus Inversus Syndrome typically display a distinct facial appearance due to the following four features:
- Blepharophimosis: A narrowing of the horizontal eye opening.
- Ptosis: Drooping of the upper eyelids that may obstruct vision.
- Epicanthus inversus: A vertical fold of skin starting from the lower eyelid and extending upward.
- Telecanthus: An increased distance between the inner corners of the eyes.
How is BPES diagnosed and what tests should I ask for?
Diagnosis of BPES is primarily clinical, meaning a doctor identifies the condition through a physical examination of the eyes. To confirm the diagnosis and determine the specific type (Type I or Type II), your physician should order genetic testing for the FOXL2 gene. Type I BPES is also associated with premature ovarian insufficiency in females, which requires additional endocrine evaluation.
When should I seek medical evaluation?
You should consult an ophthalmologist or a clinical geneticist if you notice these eyelid characteristics in a newborn or child, especially if the drooping eyelids interfere with normal visual development (amblyopia). If you are an adult and suspect you have BPES, discuss your family history and physical features with a genetic counselor. Do not be discouraged if your local physician is unfamiliar with the condition; provide them with information from reputable sources like the NIH GARD or Orphanet to help guide your care.
What is the difference between normal variation and BPES?
While many people have mild epicanthal folds or slight ptosis, Blepharophimosis Ptosis Epicanthus Inversus Syndrome is a specific, congenital constellation of all four features mentioned above. Unlike common variations, BPES is consistently present at birth and is caused by a mutation in the FOXL2 gene, which is distinct from isolated ptosis or benign facial features.
