[A familial case of drusen of the optic disk]

Abstract

The present abstract is about a case of drusen of the optic disc (DOD), consisting of three members, belonging to two generations: the mother (41 years) and two daughters (16 and 19 years). Their personal records showed nothing special, except case III-2 with crisis equivalent to the epileptic ones. No changes of the visual acuity and of the visual field were found. Ophthalmoscopy and angiofluorography showed: a bilateral and superficial location of the DOD; no vascular anomalies (discal and peridiscal) or other retinal changes; a trend towards flattening and getting more mat of the DOD, in older cases. It is debated upon the possibility that a single gene might be involved, responsible for an autosomal dominant or autosomal recessive transmission mode.
