Epiblepharon with inverted eyelashes in Japanese children. I. Incidence and symptoms.

Epiblepharon commonly occurs in Japanese infants and tends to disappear spontaneously with age. We examined 4449 Japanese children aged 3 months to 18 years for epiblepharon associated with inverted eyelashes touching the cornea. The condition was evident in 441 cases. We found that the incidence of epiblepharon decreased with age, but about 2% of high school students still had the condition. No sexual predilection was found. Lower eyelids were commonly involved bilaterally. Most cases of epiblepharon produced no or mild symptoms.
