Three children with ceroid-lipofuscinosis and their mother were investigated fluorescein angiographically and electrophysiologically after definitive diagnosis of the oldest child had been made from a brain biopsy specimen studied biochemically, histopathologically, and ultrastructurally. The diagnostic features of the two classes of familial amaurotic idiocy (the gangliosidoses and the ceroid-lipofuscinoses) are reviewed with emphasis on the importance of the fundus picture and fluorescein angiographic study in differentiating the two classes of disease and in identifying affected siblings.
