چکیده
BACKGROUND Duane retraction syndrome (DRS) is the most common of the ocular congenital cranial dysinnervation disorders .This study evaluates the types of Duane syndrome and its management in patients presenting to the paediatric and strabismus unit of a tertiary care eye hospital. METHODS This case series study involved 41 patients diagnosed with Duane syndrome between January 2007 and December 2009. History of presenting complaints, past treatment and family history were recorded. Ocular examination and orthoptic assessment was carried out RESULTS Forty one patients were included in this case series study. It involved 10 right eyes, 27 left eyes and both eyes of 4 patients. There were 26 females and 15 males. Type-1 Duane syndrome was present in 28 (68.3%), type 2 in 8 (19.5%), Type-3 in 4 (9.8%) and type-4 with synergistic divergence was present in 1 (2.4%) patient. Comorbidity was present in 6(14.6%) patients. Surgery was carried out in 26 (63.4%) patients either for abnormal head posturing or significant upshoots or down shoots. Upshoots noted in 21 eyes, were completely or partially resolved in 15 cases. Among 4 patients with down shoots on adduction, complete resolution was seen in 1. The pre and post-operative measurements of horizontal deviation showed statistically significant difference in Duane type-1 and 2, where as in Duane type-3 it was not significant. One patient with type-4 Duane did not undergo surgery. CONCLUSIONS Recession of the horizontal recti is more effective in treating the upshoot or down shoot associated with DRS as compared to recession and y-split of the horizontal muscle.

متن کاملCongenital inverse Duane's retraction syndrome: A rare presentation
A 12-year-old girl presented with esotropia and face turn since birth. Ocular motility examination showed restricted abduction associated with down shoot and retraction on attempted abduction characteristic of inverse Duane's retraction syndrome. To the best of our knowledge, this is one of the very few reported cases of congenital inverse Duane's retraction syndrome.
متن کاملMotion perception tested with reversing grating in Duane's syndrome.
Many papers have reported that motion perception asymmetry (MPA) is replaced by motion perception symmetry (MPS) by the 4th to 5th month after birth, when stereopsis starts to occur in normal infants. Duane's syndrome is a congenital motor abnormality, it does, however, reportedly show good stereopsis. We confirmed the stereopsis in Duane's syndrome and checked the motion perception (MP) by usi...
