Outcome of Scleral Buckling Surgery in Rhegmatogenous Retinal Detachment

Abstract

A longitudinal study was carried out in the vitreo-retina clinic of the National Institute of Ophthalmology and
Hospital (NIO&H) on 30 eyes of 25 patients who were treated with scleral buckle (SB) surgery during the
period of October 2004 to September 2005 of either sex. The aim of this study was to determine the outcome of
SB surgery in Rhegmatogenous retinal detachment (RRD). The main entry criteria for this study were
primary RRD treated with SB and for which 12 weeks of follow-up were available. The eyes with proliferative
vitreoretinopathy or with history of SB surgery, vitrectomy, posterior segment open-globe trauma or
significant concurrent eye disease e.g. amblyopia, macular disease etc were excluded from this study. Overall
twenty-four eyes (80%) achieved retinal reattachment with one SB procedure (encircling or segmental); the
median 12-week visual acuity was 6/12. Three additional eyes (10%) achieved retinal reattachment with one
vitreoretinal procedure; the median 12-week visual acuity was 6/9. Three eyes (10%) never achieved retinal
reattachment despite one additional vitreoretinal procedure, and 12-week visual acuity was no perception of
light. It can be concluded that SB for primary RRD achieves anatomical efficacy and preservation of central
vision in the majority of eyes.

Key words: Scleral buckle; Rhegmatogenous retinal detachment outcome.
