Abstract

Purpose: To find out the prevalence of Duane’s retraction syndrome in strabismic patients and its types. Methodology: In this descriptive cross sectional study, 900 strabismic patients presenting in orthoptic clinic of Mayo Hospital from January 2010 to October 2011 underwent orthoptic assessment. Visual Acuity was recorded with VLC monitor. Orthoptic assessment and ocular motility testing were done. Diagnosis was then made on the basis of horizontal eye movement limitation, Globe Retraction with Palpebral Aperture Narrowing on attempted adduction, enopthalmos and Upshoot/ Downshoot. Results: Out of 900 strabismic patients, 29(3.2%) patients had Duane Syndrome. 25(2.7%) patients had Duane type I, 3(0.3%) patients had Duane Type III and 1(0.1%) patient had Duane Type II. Conclusion: The prevalence of Duane Retraction Syndrome was found to be 3.2% which is significantly high. Keywords: Duane retraction syndrome, globe retraction, peplpebral aperture narrowing
