Improved control of intermittent exotropia with part-time patching.

Area of Science:

• Ophthalmology
• Pediatric Ophthalmology
• Strabismus Research

Background:

• Intermittent exotropia is a common strabismus affecting distance and near vision control.
• Effective management strategies for intermittent exotropia, particularly in young children, are crucial.
• Part-time patching is a potential therapeutic option requiring further evaluation.

Purpose of the Study:

• To evaluate the efficacy of part-time patching versus observation for improving distance exodeviation control.
• To analyze the effect of patching on distance control scores in a subgroup of children with intermittent exotropia.

Main Methods:

• Post hoc analysis of a randomized clinical trial involving 306 children aged 3 to <11 years.
• Participants had intermittent exotropia or prolonged recovery after monocular occlusion at baseline.
• Assessed changes in distance and near fixation control scores at 3 and 6 months.

Main Results:

• Part-time patching showed greater improvement in distance control scores compared to observation at both 3 months (0.4 points) and 6 months (0.3 points).
• Improvements were statistically significant, suggesting a beneficial effect of patching on distance control.

Conclusions:

• Part-time patching may enhance distance control in children with intermittent exotropia and a baseline control score of 2 or worse.
• Further research is warranted to confirm these findings due to the post hoc nature of the subgroup analysis.
