[Early stages of angiomatosis of the retina and optic nerve disk].

Based on 13 years observations of three generations of relatives with v. Hippel-Lindau's disease the authors focus attention on early stages of clinically detectable retinal angiomatosis. They supplement these findings by an angioma on the optic disc in one sporadic case. They consider the ophthalmological diagnosis of priority importance for the patients and risk relatives and recommend a concept of presymptomatic screening to detect other organ sites of the disease. Early detection and treatment of lesions on eyes and other organs improves the prognosis and reduces early mortality.
