Vitreous haemorrhage in tuberous sclerosis. Report of two cases.

Abstract

Tuberous sclerosis is a well-defined clinical entity characterized by a triad of epilepsy, mental retardation, and adenoma sebaceum, with excellent clinical descriptions elsewhere (Critchley and Earl, I932; Lagos and Gomez, I967). The principal ocular manifesta- tions comprise retinal tumours of two morphological types (van der Hoeve, 1920, 192I). Elevated mulberry-like tumours are found characteristically in the posterior pole where they may resemble drusen of the disc. Each tumour appears as a whitish-grey glistening mass, studded with nodules which may become cystic. A second type occurs in the retinal periphery which is flat, white or grey, circular or oval, and frequently multiple, ranging up to half the size of the optic disc (Koch and Walsh, I939).
