Abstract

Introduction: Strabismus means ocular misalignment, whether caused by abnormalities in binocular vision or by anomalies of neuromuscular control of ocular motility. A successful strabismus surgery should balance muscle forces to restore central or peripheral fusion when possible or acceptable cosmesis when fusion cannot be accepted. Weakening procedure on rectii constitute an important surgical modality for correcting various forms of strabismus.

Material and Methods: Study was performed in 2006-2007 on thirty patients of comitant horizontal strabismus who had undergone surgical correction for deviation in Deptt. of Ophthalmology, GGS Medical College, Faridkot. After preliminary ocular examination which included anterior segment & fundus examination, angle of deviation was measured by prism bar cover test followed by squint surgery. 15 patients had undergone conventional recession and rest of 15 patients had undergone hang-back recession surgery. Follow up was done at 1 week, 1 month & 3 months post op.  

Results: It was observed that at third month postop 86.66% of patients with conventional recession achieve deviation less than 10 PD with respect to 80% of patients with hang-back recession.

Conclusion: There was no significant difference in the success rate in relation to angle of deviation for both types of surgical techniques. The results of this study suggested that conventional hang-back recession surgery is a predictable alternative to conventional recession surgery.

Keywords: Horizontal strabismus, conventional recession , hang-back recession.
