Purpose:
Residual or recurrent esotropia is a common problem following bilateral medial rectus recessions for esotropia, and various surgical techniques have been advocated. We have favored bilateral lateral rectus resections.
Methods:
We reviewed our results in 25 patients, aged 7 to 89 months (mean 27 months), with a follow-up of 7 to 95 months (mean 39 months) following the second surgery. Survival analysis was used, with success (survival) defined as alignment within 10 PD at last follow-up.
Results:
Median survival was 84 months with an estimated mean survival of 55 months. There are 15 of 25 patients (60%) currently successful. There were 8 undercorrections and 2 overcorrections. Three patients, included among those not successful, required a third procedure. Survival was similar to previous reports of primary esotropia and consecutive exotropia.
Conclusions:
Our results suggest that bilateral lateral rectus resection is a reasonable surgical option in the treatment of residual esotropia following recessions of both medial recti.
