Abstract
PURPOSE: To evaluate the outcome of rhegmatogenous retinal detachment (RRD) surgery in eyes with preplaced glaucoma drainage device (GDD) with respect to intraocular pressure (IOP) control as well as success of retinal detachment (RD) surgery. METHODS: It is a retrospective case series. The case records of patients who underwent RD surgery after GDD implantation from 2000 to 2014 were screened. The demographic data, ocular examination findings at all visits, details pertaining to retinal detachment and its repair, and the postoperative course was documented. RESULTS: Twelve patients were included in study. The mean age of patients was 24.3 years (median 11 years; range 3-72 years). Male: Female ratio was 3:1. Mean duration between GDD and RD was 24 months (4 days-91 months). Of the ten eyes that underwent surgery, nine eyes underwent pars plana vitrectomy, and in one eye scleral buckling was done. GDD was removed only in one eye. At final follow-up, retina was attached with controlled IOP in 6 (60%) eyes, of which 5 (50%) had improvement in best corrected visual acuity. CONCLUSION: Pars plana vitrectomy was required in almost all cases for the management of RD in eyes with preplaced GDD. Retinal reattachment with good IOP control could be achieved in 60% of eyes. Removal of the drainage device was not essential for the effective management of the RRD in most cases. With multidisciplinary approach, close follow-up and timely intervention, vision can be preserved along with glaucoma control and successful retinal reattachment.
