Factors influencing response to strabismus surgery

Area of Science:

• Ophthalmology
• Strabismus Surgery
• Pediatric Ophthalmology

Background:

• Strabismus surgery aims to correct eye misalignment.
• Predicting surgical outcomes is crucial for patient management.
• Previous hypotheses suggested ocular axial length influences surgical response.

Purpose of the Study:

• To evaluate the correlation between strabismus surgery response and preoperative deviation.
• To determine if axial length, age, or refractive error improve prediction beyond preoperative deviation.
• To refine understanding of factors influencing strabismus surgery outcomes.

Main Methods:

• Analysis of 116 patients undergoing strabismus surgery.
• Measurement of ocular alignment change per millimeter of rectus recession.
• Statistical correlation analysis including preoperative deviation, axial length, age, and refractive error.

Main Results:

• A significant correlation was found between surgical response and preoperative deviation in esotropic and exotropic patients.
• Inclusion of axial length, age, and/or refractive error did not significantly improve prediction accuracy.
• A significant inverse correlation between surgical response and axial length was observed, but deemed clinically less important than preoperative deviation.

Conclusions:

• Preoperative deviation is the primary predictor of strabismus surgery response.
• Axial length, while correlated, has a less significant clinical impact on surgical outcomes compared to preoperative deviation.
• Current predictive models for strabismus surgery may not require complex factors beyond initial eye alignment.
