Microscopic scleral buckling under direct vision with application of corneal contact lens

Abstract

Objective To study the efficacy of microscopic scleral buckling under direct vision using corneal contact lens for the treatment of rhegmatogenous retinal detachment. Methods The data of 40 eyes of 40 consecutive clinical cases with rhegmatogenous retinal detachment from Jul. 2012 to Dec. 2014 were collected and analyzed retrospectively. They underwent surgery of microscopic scleral buckling under direct vision with application of corneal contact lens. Twenty-six cases were male, and 14 cases were female. The age ranged from 13 to 87 years, average (34.48±16.47) years. The course of disease was 3-180 d, average (36.20±4.80) d. The follow-up time was 1 year. Results Accurate retinal hole localization were done in all 40 cases. The retina was reattached in 39 cases (97.50%). One case (2.50%) with jelly-like subretinal fluid received vitrectomy due to failed of retinal reattachment. During the surgery, a new retinal tear was found in 1 case after transcleral outflow drainage of subretinal fluid, and the tear was accurately localized and cryocoagulated immediately. There was no other complication in operation. BCVA was significantly improved after surgery (t=6.794, P=0.000). Conclusion Microscopic scleral buckling under direct vision with application of corneal contact lens is a recommendable surgery for rhegmatogenous retinal detachment. It can provide good retinal reattachment with less complications, with supplying clear operation view, accurate retinal tear localization, and appropriate cryotherapy and buckling.
