[Leber's optic atrophy].

On the basis of observation of personal cases the authors discuss the clinical course and the natural history of Leber's disease. Particular attention is called to the diagnostic difficulties; the value of the angiographic examination in the acute phase of development of the condition is stressed. An appropriate differential diagnosis enabled us to avoid in these patients unnecessary and iatrogenic neuro- and radio-diagnostical examinations. Possibilities of treatment and the aspects of activity of this disease are also discussed.
