SUPPLEMENTAL SCLERAL BUCKLE IN THE ERA OF SMALL INCISION VITRECTOMY AND WIDE-ANGLE VIEWING SYSTEMS.

Abstract

To evaluate trends and outcomes of scleral buckle as adjunct to pars plana vitrectomy for management of retinal detachment. Retrospective case series including 300 consecutive cases of retinal detachment that underwent pars plana vitrectomy. The series was divided into three consecutive groups: Group A (first 100 cases), Group B (second 100 cases), and Group C (third 100 cases). Three hundred eyes of 289 patients, mean age 61.0 years, were included in the study. The mean follow-up was 31.3 months for Group A, 28.5 months for Group B, and 12.0 months for Group C (P < 0.001). The baseline mean logarithm of the minimum angle of resolution equivalent was 1.58 for Group A, 1.31 for Group B, and 1.33 for Group C (P = 0.15). Supplemental scleral buckle was performed in 53% of Group A, 35% of Group B, and 17% of Group C (P < 0.001). Single surgery reattachment rate was 93% for Group A, 95% for Group B, and 97% for Group C (P = 0.48). The mean change in logarithm of the minimum angle of resolution equivalent was -0.84 for Group A, -0.81 for Group B, and -0.71 for Group C (P = 0.50). The study demonstrates decreasing use of supplemental scleral buckle in the era of small gauge vitrectomy surgery and wide-angle viewing systems while the outcomes remain stable. Selective, less frequent use of supplemental scleral buckle is compatible with good anatomical and visual outcomes.
