The authors review surgical outcomes for 317 children having surgery for esotropia (n=235) or exotropia (n=82) for comparative analysis using survival curves. Esotropia surgery was undertaken at a mean of 42 months; exotropia surgery at a mean of 60 months of age. Overall, 14% required a second surgical procedure with a mean of 41 months follow-up. Of esotropia cases, 21 needed a second procedure and 29 had deviations >20PD (19 recurrent / residual esotropia and 10 consecutive exotropia). Of exotropia cases eight needed a second procedure and 21 had deviations >20PD (six consecutive esotropia and nine recurrent / residual exotropia). At one month postoperatively, survival was 100% for esotropia and 98.9% for exotropia. At six months postoperatively, survival was 95.2% for esotropia and 90.0% for exotropia. At one year, 90.7% for esotropia and 86.7% for exotropia. At two years, 84% for esotropia and 75.7% for exotropia. At five years, 74% for esotropia and 55.9% for exotropia. Mean survival time for esotropia was 96.8 months and 73.7 months for exotropia which was significant, p=0.008.
