Retrospective study of histologically confirmed intraocular tumors at the Eye Clinic of the Vinohrady Faculty Hospital in Prague

: The authors evaluated statistically in a retrospective study the histological findings of a total of 182 intraocular tumours assembled at the Ophthalmological Clinic, Vinohrady Faculty Hospital Prague in 1992-2000. The histological material was obtained from 147 patients by enucleation of the bulbus and in 35 patients by surgical resection. In 97.2% the authors proved the malignant character of the tumour. In 95% an uveal melanoma was involved. In malignant melanomas of the choroid the following parameters were investigated: site, size, histological type, state of Bruch's membrane and extrascleral propagation of tumour. In 67% the melanoma was in the choroid, in 21% in the ciliary body and in 12% in the iris. As to size, large and extremely large melanomas predominated (66%). Histologically melanomas of the mixed and spindle-cell type were most frequent (93%). Bruch's membrane was damaged in 48% melanomas. Transscleral extension of the tumour was present in 9% malignant choroid melanomas.
