Strabismus surgery may eliminate need for bifocals in patients with accommodative esotropia
Strabismus surgery may eliminate the need for bifocal glasses in patients with accommodative esotropia, a retrospective study found.
Gregg T. Lueder, MD, and Alan A. Norman, MD, of St. Louis, evaluated the outcomes of strabismus surgery in 16 patients with a high AC/A ratio who required bifocal correction for accommodative esotropia.
Binocularity remained unchanged in 13 patients and improved in three patients. Surgery eliminated the need for refractive correction in eight patients. All patients achieved microtropias and maintained fusion without bifocals, according to the study. Five patients required two surgeries, the authors noted. This included two of three patients with negative preoperative prism adaptation tests (PATs) and three of 13 patients with positive preoperative PATs, according to the study.
Preoperative PATs may help predict the risk of requiring more than one surgery, the authors said.
The study is published in the October issue of the American Journal of Ophthalmology.
