Abstract
-
Twenty patients with small angle esotropia of 12 delta - 20 delta were treated with a unilateral medial rectus recession of 4.0 - 5.0mm. Eighteen of the 20 patients (90%) showed 8 delta or less horizontal deviations after surgery. The average amount of angle corrected with 4.0mm recession in 15 delta esotropia group was 15 delta, that with 4.5mm recesstion in 15 delta - 20 delta esotropia group was 14.8 delta and that with 4.5 - 5.0mm recession in 20 delta esotropia group was 15.2 delta. The average amount of angle corrected with 4.0mm, 4.5mm, 5.0mm recession were 12 delta, 15 delta and 14.6 delta respectively. The recession of one medial rectus muscle is a safe, predictable and simple procedure for the surgical treatmont of small angle esotropia.
