In adults, aponeurotic blepharoptosis is the most common type of ptosis. However, myogenic ptosis is the predominant cause, and bilateral aponeurotic ptosis is very rare among children. Here, we report a previously healthy 10-year-old Japanese girl with bilateral aponeurotic blepharoptosis who presented initially with bilateral blepharoptosis for about 4years. This case report shows that history taking and careful observation of the patient lead to an accurate diagnosis, and aponeurotic ptosis should be considered in the differential diagnosis of bilateral blepharoptosis among children.
