Retinoblastoma was clinically diagnosed in 38 patients in the University Hospital between 1968 to 1988. White pupil or cat's eye reflex, found in 25 patients, was the most common symptom. Four patients refused any form of treatment. Of the 27 histopathologically confirmed cases, 16 were males and 11 were females. There was no ethnic group predominance, although a male preponderance was observed among Malay patients (M:F 3:1, p less than 0.05). Treatment in cases with unilateral disease, without extra ocular extension consisted of enucleation of the involved eye, with close examination of the contralateral eye in follow-up. In cases presenting with bilateral tumour the worse eye was removed. Of 20 cases of histopathologically proven unilateral retinoblastoma treated surgically, 12 patients survived for a mean period of 4.5 years (Range: 1-19 years). The defaulter rate for this group of patients was 55%. None of the 7 cases of bilateral retinoblastoma survived beyond 5 years (Mean survival 2.5 years).
