Resolution in partially accomodative esotropia during occlusion treatment for amblyopia

Area of Science:

• Ophthalmology
• Pediatric Ophthalmology
• Strabismus Management

Background:

• Partially accommodative esotropia often coexists with amblyopia.
• Amblyopia treatment, typically patching, is crucial for visual development.
• The optimal timing of surgical intervention versus amblyopia treatment in these cases remains a consideration.

Purpose of the Study:

• To assess changes in eye alignment in patients with partially accommodative esotropia during amblyopia treatment.
• To determine if initial amblyopia management influences the need for strabismus surgery.

Main Methods:

• Retrospective analysis of 63 patients with partially accommodative esotropia undergoing occlusion therapy for amblyopia.
• Evaluation of changes in deviation angles before and during occlusion treatment, with and without glasses.

Main Results:

• Mean deviation angle decreased from 45 PD to 11 PD with glasses after occlusion therapy.
• Amblyopia resolved in 71.5% of patients.
• Only 38% required surgery after amblyopia treatment, compared to an estimated 81% if surgery preceded amblyopia management.

Conclusions:

• Initial amblyopia treatment is recommended for high hypermetropic, partially accommodative esotropia cases with a history of strabismus.
• Delaying surgery allows for potential improvement in the non-accommodative strabismus component.
• Prioritizing amblyopia treatment can significantly decrease the rate of subsequent strabismus surgery.
