Retinal detachment in black South Africans
1Department of Ophthalmology, University of Natal, King Edward VIII Hospital, Durban.
Summary
Rhegmatogenous retinal detachment is uncommon in black patients, with a low incidence rate. Factors like younger age, blunt trauma, and late presentation contribute to surgical challenges and lower reattachment success rates.
Area of Science:
- Ophthalmology
- Retinal Diseases
- Public Health
Background:
- Rhegmatogenous retinal detachment (RRD) is a significant cause of vision loss.
- Previous studies suggest a lower incidence of RRD in Black patients, but specific characteristics and outcomes in this population require further investigation.
Purpose of the Study:
- To determine the incidence and clinical characteristics of RRD in Black patients at a specific hospital.
- To identify factors influencing surgical outcomes and reattachment success rates in this demographic.
Main Methods:
- Retrospective review of 114 RRD cases in 112 Black patients over a 5-year period (1987-1991).
- Exclusion of cases with penetrating trauma and diabetic retinopathy.
- Analysis of patient demographics, clinical presentation, surgical procedures, and reattachment success rates.
Main Results:
- Low annual incidence of 0.46/100,000 population served.
- Patients were relatively young (37.5% under 30), with a 2:1 male-to-female ratio.
- High incidence of blunt trauma (29.8%), late presentation, large posterior breaks (15.7%), and severe proliferative vitreoretinopathy (33.3%).
- Vitrectomy with tamponade was the primary procedure in 32.5% of cases.
- Reattachment success rate was 72.8%.
Conclusions:
- Confirms the low incidence of RRD in Black patients.
- Younger age, blunt trauma, and severe ocular conditions contribute to poorer surgical outcomes.
- The underlying reason for the low incidence remains unknown, with stronger retinal adhesion postulated.
