ABSTRACT
Purpose: To assess the incidence of strabismus, relationship of strabismus with type and width of scleral buckle after scleral buckling surgery for retinal detachment.
Methods: Retrospective analysis was done of 360 eyes of 344 patients treated for rhegmatogenous retinal detachment with scleral buckling surgery between January 2008 and January 2013.
Results: The mean age of patients was 38.45 ± 18.12 years (range: 7 to 89 years). Strabismus was detected in 48 out of 344 (13.95%) patients at 6 weeks after scleral buckling surgery. Horizontal deviation was the commonest type. Incidence of strabismus was higher after repeat scleral buckling surgery (4/9, 44.4%) compared to patients who had single scleral buckling surgery (44/335, 13.1%) (P=0.02). Strabismus was observed in 18.5% of patients with implants, compared to 11.3% of patients who received explants (P=0.02). Strabismus surgery was performed on 2 (4.1%) cases.
Conclusion: Horizontal strabismus is common after scleral buckling surgery for repair of retinal detachment. Repeat scleral buckling and use of implants resulted in a higher incidence of strabismus in the postoperative period. Majority of these cases resolve with conservative management.
