BACKGROUND: To report the long-term outcome of a series of 49 @entity1 who underwent three horizontal muscle squint surgery for large angle infantile @entity5971 . METHODS; The @entity1 records were retrospectively reviewed of 49 (24 @entity1 [49%], 25 @entity1 ) consecutive @entity1 with infantile @entity5971 of angle > or =60 Delta, who had undergone three horizontal muscle surgery performed by one surgeon (author GG). Surgery consisted of bilateral medial rectus recession combined with graded unilateral lateral rectus resection. Surgeries were carried out over a 6-year period with a mean follow-up period of 32.9 months (3.7-71.8 months). RESULTS: Using Kaplan-Meier life-table analysis, cumulative surgical success (orthotropia +/-10 Delta) was 93.9% at 1 week, 91.8% at 2 and 6 months, 87.7% at 12 and 18 months, 79.9% at 2 years, 77.1% at 3, 4 and 5 years, and 70.6% at 6 years. The mean preoperative deviation was 68.7 Delta. The mean age at surgery was 12.9 months. The failure rate was independent of preoperative deviation. Prevalence of @entity5971 (>10 Delta) varied from 2.0% at 1 week to 17.0% at 6 years. Similarly the prevalence of consecutive exotropia (>10 Delta) varied from 4.0% at 1 week to 12.4% at 6 years. CONCLUSION; Operating in a graded fashion on three horizontal muscles in @entity1 with large angle infantile @entity5971 has a high success rate, even over long-term follow up. Based on the study's results, amounts of surgery for a given angle of strabismus are proposed.
