[Vitelliform degeneration of the macula and Leber's amaurosis. Discussion on nosology (author's transl)].

A description of vitelliform degeneration of the macula in 6 year-old child, and Leber's amaurosis in his first cousin aged 7. The evolution has been followed and studied for 18 months from the point of view of slit-lamp examination, function and electrophysiology. The intrafamilial association of these two types of hereditary tapeto-retinal degeneration allows a discussion on their respective nosological character in the light of the small amount of literature available.
