Visual and anatomical outcomes in congenital glaucoma-related rhegmatogenous retinal detachment

Abstract

Purpose: To study the visual and anatomical outcomes after at least five years follow up of surgically repaired rhegmatogenous retinal detachment (RRD) in patients with congenital glaucoma

Methods: A retrospective comparative case series of 100 eyes with RRD in patients known to have congenital glaucoma was conducted. The data of 25 eyes was collected at the time of this abstract submission. Of those, 10 eyes underwent surgical retinal repair. The primary outcome measures included the final visual and anatomical results of surgical intervention

Results: The mean age of the patients was 20 years (range: 13 to 33 years). The mean duration of follow-up was 10.8 years (range: 5 to 21 years). All patients were diagnosed with congenital glaucoma within the first year of life and only two were diagnosed after the first month. The mean age of onset of RRD was 8.7 years (range: 4.2 to18.8 years). The median baseline visual acuity was hand motion (range: light perception to 20/160). All eyes underwent pars plana vitrectomy with internal tamponade, with or without scleral buckling. Among operated eyes, all except two eyes (80%) were attached on last follow up. At last follow-up, the median visual acuity was hand motion (range: No light perception to 20/80) and No light perception (range: light perception to No light perception) for operated and non-operated eyes respectively. The difference was not significant between the two groups

Conclusions: Our results suggest that surgical repair of congenital glaucoma-associated RRD has a lower success rate than reported for typical RRD cases. Moreover, successful repair dose not appear to significantly alter the final visual outcome mainly due to associated ocular co-morbidities such as amblyopia and optic neuropathy
