Retrospective review of ocular alignment after large-angle congenital esotropia surgery

Results: The study period was from January 1992 to September 2003. Fifty-two patients were included in the study group. The pre-operative angle of deviation ranged from 50∆–85∆. Patient ages ranged from 15 months to 22 years, with a mean of 5.3 years and a median of 4 years. The gender distribution was 42% male (n = 20) and 58% female (n = 28). Surgery was successful (within 10∆ of orthophoria) in 77% (n = 40), a partial success (10∆–20∆ from orthophoria) in 17% (n = 9) and a failure (> 20∆ from orthophoria) in 6% (n = 3). No statistically significant relationship was found between surgical success and patient age at the time of surgery.
