[Epidemiologic aspects of retinoblastoma in a tropical region].

The authors are publishing the epidemiologic aspects of retinoblastoma in a cameroonian area. The study is prospective and is carried out in the eye clinic of CHU over a period of 7(1/2) years. We include all patients diagnosed and confirmed histologically after enucleations to have retinoblastoma. The frequency of retinoblastoma is 0.83% per 10000 consultations. The sex ratio is 1/6 (two boys and 12 girls) ans the mean age of patients on first consultation (visit) is 38 months (between 3 months and 6 years 7 months). 85.55% of the retinoblastomas are sporadic and the disease is lethal in 78.57% of cases.
