Preoperative Variables Associated with Surgical Outcome for the Correction of Exodeviation

Area of Science:

• Ophthalmology
• Strabismus Surgery
• Clinical Outcomes Research

Background:

• Exodeviation surgery success rates reported in existing literature are variable.
• Understanding factors influencing surgical outcomes for exodeviation is crucial for patient management.
• There is a need for region-specific data on exodeviation surgery outcomes.

Purpose of the Study:

• To determine the success rate of exodeviation surgery in Atlantic Canada.
• To identify preoperative variables associated with successful surgical outcomes for exodeviation.
• To contribute to the understanding of factors influencing strabismus surgery success.

Main Methods:

• Retrospective chart review of 176 patients treated for exodeviation between 2011-2018.
• Statistical analysis including chi-square, Fischer's exact test, and binary logistic regression.
• Comparison of preoperative variables between successful and unsuccessful surgical outcomes.

Main Results:

• The overall success rate for exodeviation surgery was determined to be 43%.
• Smaller preoperative deviation size (at near and distance) and basic exodeviation classification were associated with successful outcomes.
• Left eye visual acuity demonstrated a statistically significant association with surgical success.

Conclusions:

• Exodeviation surgery outcomes are variable, consistent with previous research.
• Preoperative deviation size and exodeviation subtype are important factors influencing surgical success.
• These findings highlight potential predictive variables for exodeviation surgery outcomes and suggest areas for future research.
