*Dr. Rofadun Nisa and Dr. Afroz Khan

ABSTRACT

Purpose: To report the prevalence and causes of amblyopia among patients of Simple congenital ptosis. Design: Prospective observational. Material and Method: A prospective observational single institutional study was conducted on 37 eyes of 35 patients having Simple Congenital Ptosis. Visual acuity was measured using Snellen acuity testing. Results: The study conducted on 37 eyes of 35 patients revealed that 13.5% (05) of patients with simple congenital ptosis had amblyopia. Among these patients, the majority of patients (80%) had amblyopia as result of occlusion by ptotic lid while only 20% patients had amblyopia as a result of refractive errors. Conclusion: Early examination and follow-up of patients with Simple congenital ptosis is important to diagnose and treat any subsequent amblyopia. Surgery may be indicated should stimulus deprivation amblyopia develop.
