Abstract

Background

To estimate incidence and surgical factors associated with the occurrence of OCR during strabismus surgery.

Methods

After IEC approval, patients who underwent strabismus surgery under general anesthesia were enrolled in this study. Heart rate was measured at baseline, at dissection , at maximum traction and cutting muscle was noted. More than 20 % reduction in heart rate was considered as OCR ; number of muscles , which muscle was being recessed or resected was noted and association with surgical factors was seen

Results

A total of 65 patients (90 muscles ) were operated. The incidence of OCR was 10.7%(7) , age and two muscle surgery (p<0.05and p<0.05) were significantly associated with occurrence of OCR. Medial rectus resection was not significantly correlated (p = 0.09). Conclusion OCR prevalence in strabismus surgery was 10.7 % in our set up. Age, patients with esotropia and two muscle surgery was a significant risk factors for OCR occurrence
