Outcomes after the surgery for acquired nonaccommodative esotropia.

Area of Science:

• Ophthalmology
• Strabismus Surgery
• Pediatric Ophthalmology

Background:

• Acquired nonaccommodative esotropia (ANAET) is a condition requiring surgical intervention.
• Analyzing surgical outcomes is crucial for managing ANAET.

Purpose of the Study:

• To evaluate the surgical outcomes in patients with acquired nonaccommodative esotropia (ANAET).
• To determine the success rate and identify factors influencing surgical results for ANAET.

Main Methods:

• Retrospective review of 35 patients with ANAET undergoing surgery.
• Follow-up of at least 6 months to assess postoperative esodeviation angle and success rate.
• Surgical success defined as alignment within 8 prism diopters (PD) at distance and near.

Main Results:

• Preoperative mean esodeviation was approximately 37-38 PD.
• Postoperative esodeviation remained stable from day 1 to final follow-up (mean ~4.8 PD).
• The final surgical success rate was 65.7% (23/35), with a 17.1% reoperation rate.

Conclusions:

• Surgical outcomes for ANAET are relatively favorable.
• A 65.7% success rate and 17.1% reoperation rate were observed.
• No specific factors were found to significantly influence the surgical outcome.
