Unilateral Single Horizontal Muscle Surgery with Augmented Recession for the Treatment of Moderate Horizontal Squint

Abstract

Objective: To study the effects of unilateral single horizontal muscle surgery with augmented recession for the treatment of moderate hori[1]zontal squint. Methodology: The study was conducted at Department of Ophthalmology Azra Naheed Medical College, Superior University Lahore & University College of Medicine & Dentistry, The University of Lahore from January 2012 to June 2013. In this study 37 patients with esotropia or exotropia less than 45 prism diopteres (20-45∆) were included. Patients with paralytic or cicatricial squint or had surgery before were excluded from the study. Non-dominant single eye was operated of each patient. The rectus muscle to be recessed was dis-inserted from its insertion and after maximum recession and leaving an additional loop of a non-absorbable suture it was re-inserted. Results: Out of 37 patients 34 (94 %) patients achieved correction within 08∆. All were corrected within 12∆ Conclusion: Augmented recession of unilateral single horizontal muscle is an effective way to treat horizontal squint with mild to moderate angle. Only non-dominant eye requires surgery and it is more acceptable to the patient because the risk of multiple muscle surgeries is avoided
