Abstract

PURPOSE: To evaluate the incidence, cause and clinical feature of the amblyopia in congenital ptosis.
METHODS
A retrospective review of 61 consecutive patients with congenital ptosis who had preoperative records on refractive error and strabismus was perfomed. The presence of amblyopia, strabismus, anisometropia, and severity of ptosis were recorded.
RESULTS
Eleven out of 61 patients (18.0%) had amblyopia, 6 patients (9.8%) had strabismus, and 18 patients (29.5%) had anisometropia. Among 11 amblyopic patients 10 patients (90.9%) had unilateral ptosis and amblyopia in that ptotic eye. Eight of 11 patients (72.7%) had astigmatism of more than 1.5 diopters in ptotic eye only. There was no statistically significant relationship between the severity of ptosis and the incidence of amblyopia (P>0.05).
CONCLUSIONS
The high incidence of anisometropia, strabismus, and astigmatism was found in congenital ptosis with amblyopia. This warrants compulsive examination of refractive error and strabismus to prevent amblyopia in congenital ptosis.
