Indian Journal of Clinical and Experimental Ophthalmology (IJCEO) is open access, a peer-reviewed medical journal, published quarterly, online, and in print, by the Innovative Education and Scientific Research Foundation (IESRF) since 2015. To fulfil our aim of rapid dissemination of knowledge, we publish articles ‘Ahead of Print’ on acceptance. In addition, the journal allows free access (Open Access) to its content, which is likely to attract more readers and citations of articles published in IJCEO.

Abstract
Purpose: To compare the incidence of reflex(OCR) between hang-back and conventional method of muscle recession in horizontal.
Materials and Methods: In this prospective, randomized, study, 40 consecutive patients of horizontal were evaluated. The patients were randomized into two groups based on the type of surgical recession technique employed for squint correction. Twenty patients were operated by Hang-back technique (group-1) and 20 by conventional muscle recession where the muscle tendon was sutured directly to the globe (group-2). All patients underwent evaluation which included refraction, and assessment of angle of deviation etc. ECG was monitored before surgery. During surgery heart rate (HR) was recorded as heart rate baseline (HRB), after 5 minutes of (HR5), during muscle traction (HRT), Minimum heart rate during traction of muscle (HRMin) Maximum increase in heart rate (HRMax). OCR was defined as > 20% reduction in HR during muscle traction as compared to baseline HR.
Results: Out of total 40 patients 17(42.50%) were having and 23 (57.50%) had . The overall incidence of OCR in conventional recession was found to be greater than that in hang-back recession. The mean baseline HR was 72.00± 7.391 beat/min in conventional recession group and 77.55± 7.494 beat/min in hang-back recession group.
The mean HR reduction in conventional procedure was 56.05± 8.787 beat/min. and that in hang-back procedure 61.80 ± 9.317 beat/min., which was statistically significant (p<0>
Conclusion: OCR is a common complication encountered during manipulation of muscle during surgery. Hang-back recession is a safe and effective method of muscle recession as it offers a shorter surgical time and better exposure along with lesser incidence of OCR with similar success rates when compared to conventional muscle recession.
