Etiology of pediatric acquired blepharoptosis.

Purpose: To describe the etiology of acquired pediatric blepharoptosis in a large clinical series and to elucidate the causes of the disease.

Methods: The medical records of all patients presenting with acquired blepharoptosis at two specialist ocular plastics practices and a pediatric ophthalmology practice during a period of up to 25 years were reviewed retrospectively and classified according to their diagnosis. Patients were grouped into children (<18 years), younger adults (18-40 years), and older adults (>40 years).

Results: A total of 268 patients <18 years of age were identified. The most common identifiable causes of acquired blepharoptosis in children were infantile hemangioma (n = 92 [34.3%]) and trauma (n = 41 [15.3%]). In 42 cases (15.7%) a definite diagnosis could not be made.

Conclusions: The etiology of pediatric acquired blepharoptosis can frequently be determined by history and examination; additional diagnostic tests are sometimes required. A high percentage of pediatric patients have blepharoptosis of unknown cause.
