Strabismus Following Scleral Buckling Surgery.

ABSTRACT

Purpose: The purpose was to assess the incidence of strabismus, relationship of strabismus with type, and width of the scleral buckle (SB) after SB surgery for retinal detachment. Methods: Retrospective analysis of 360 eyes of 344 patients, treated for rhegmatogenous retinal detachment with SB surgery between January 2008 and January 2013 was done. Results: The mean age of patients was 38.45 ± 18.12 years (range 7-89 years) was detected in 48 out of 344 (13.95%) patients at 6 weeks after SB surgery. Horizontal deviation was the most common type. Incidence of strabismus was higher after repeat SB surgery (4/9, 44.4%) compared to patients who had single SB 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 SB surgery for repair of retinal detachment. Repeat scleral buckling and use of implants resulted in a higher incidence of strabismus in the post-operative period. Majority of these cases resolve with conservative management.
