“…A population-based survey in India indicated that retinal diseases were the primary causes of blindness in a significant percentage (12.7%) of the studied population [3]. Though there is a general notion that black Africans have a low incidence of RD [4-9], there are evidences that RD might have been underestimated in Blacks. Foos examined the eyes of 2,334 subjects (322 of whom were African Americans) at post-mortem and found no racial variation in the age-corrected prevalence of lattice degeneration, retinal breaks or posterior vitreous detachment [10].…”

PurposeThe incidence of retinal detachment in Blacks is generally considered to be low though there are few supporting studies in Africa. This study, thus, aimed at describing the clinical profile of patients with retinal detachment in Southwest Ethiopia.MethodsA hospital-based study was done on all consecutive retinal detachment patients who presented to Jimma University Hospital over six months period. A semi-structured questionnaire was used to collect patients’ sociodemographic characteristics and clinical history. Comprehensive anterior and posterior segment eye examinations were done and risk factors were sought for. Statistical tests were considered significant if P < 0.05.ResultsA total of 94 eyes of 80 patients (1.5%) had retinal detachment (RD) and about 69% of patients were symptomatic for over a month before presentation. The mean age was 41.4 years (SD ±16.5). Fourteen patients (17.5%) had bilateral RD. At presentation, 61 eyes (64.9%) were blind from RD and 11 (13.8%) patients were bilaterally blind from RD. Rhegmatogenous RD was seen in 55 eyes (58.5%) and tractional RD in 22 eyes (23.4%). The most common risk factors were ocular trauma (32 eyes, 34.0%), myopia (23 eyes, 24.5%), posterior uveitis (13 eyes, 13.8%) and diabetic retinopathy (9 eyes, 9.6%). Most retinal breaks (25 eyes, 43.1%) were superotemporal and horse-shoe tear was the most common (19 eyes, 20.2%). Macula was off in 77 eyes (81.9%) and 38 eyes (69.1% of RRD eyes) had grade C proliferative vitreoretinopathy (PVR). Macular status was significantly associated with PVR (P=0.011), and duration of symptoms (RR=1.25, 95%CI: 1.059-1.475, P=0.040).ConclusionsA significant numbers of patients with ocular problem had retinal detachment, and nearly two third of the patients presented late. Trauma and myopia were the most important risk factors. People should be educated to improve their health seeking behavior and use eye safety precautions to prevent ocular trauma.

“…Eine weitere Untersuchung der Einwohner in Singapur ergab eine 3-fach erhöhte Inzidenz für Chinesen verglichen mit der indischer Einwohner (11,9:100.000 vs. 3,9:100.000), obwohl nur minimale Unterschiede hinsichtlich möglicher Risikofaktoren wie Myopie, äquatorialen Degenerationen, vorangegangenen Operationen oder okulären Traumata bestanden [22]. Bereits mehrfach wurde aufgezeigt, dass die Inzidenz unter dunkelhäutigen Afrikanern geringer ist verglichen mit der von Kaukasiern, wobei hier Inzidenzen von unter 1 pro 100.000 pro Jahr angegeben wurden [31,32,33]. Die Ursache für diese auffallend niedrige Inzidenz ist nicht bekannt, eine stärkere Adhäsion der Netzhaut zum retinalen Pigmentepithel Dunkelhäutiger wird jedoch postuliert [34].…”

“…5 It has frequently been reported that black Africans have a low incidence of RD. [6][7][8][9][10][11] However, these studies are based on hospital or clinic attendances, which can be misleading. In a poor country, with limited facilities for the management of RD, patients may be less likely to attend an eye clinic than patients in a wealthy country, with better health care systems.…”

Treatment of retinal detachment has been a low priority in developing countries. It is thought to be less common in India and Africa than in Europe and N America. The aetiology and presentation of retinal detachment in the Third World are affected by genetic and environmental factors. In general, patients are more likely to present late, and complex detachments are relatively more common. Despite these problems, the results of surgery are encouraging, with more than 80% final anatomical success, and over 60% of re-attached retinas obtaining vision of 6/60 or better. The management of retinal detachment in developing countries can be improved by strengthening training programmes and by developing and equipping centres to carry out retinal surgery.
