Indications and outcomes of vitrectomy surgery in a series of 1000 black African eyes

Abstract

ObjectiveTo determine the common indications for, and outcomes of pars plana vitrectomy surgery among black Africans in a low-resource setting.Methods and AnalysisA retrospective, non-comparative case review was undertaken. Data from 1000 consecutive eyes of 1000 patients in a single centre who underwent pars plana vitrectomy surgery between May 2005 and July 2013 were used for the study. Demographic data, primary indication for surgery, ocular status and outcomes were assessed.ResultsRhegmatogenous retinal detachment was the most common primary indication occurring in 61.8% of eyes. Diabetic vitrectomy, trauma and proliferative sickle cell retinopathy were also common indications occurring in 10.1%, 6.1% and 4.5% of eyes, respectively. At presentation, 33% of patients with retinal detachment had some form of proliferative vitreoretinopathy, and half of those had the more advanced grades C and D. Patients presented on an average of 13.5 months after onset of symptoms. As a result, visual outcomes were less than other reported studies.ConclusionRetinal detachment was the most common indication for vitrectomy, but even these cases presented late with an advanced presentation. This study highlights the need for affordable and accessible vitreoretinal services in Sub-Saharan Africa and increased awareness of general eye health, along with strategies to reduce trauma and identify early those at risk of chronic eye diseases, such as diabetic retinopathy and sickle cell retinopathy.
