Haemangioma of the optic disc.

Isolated capillary haemangiomata of the optic disc are uncommon; they may be associated with the von Hippel-Lindau syndrome. Renal carcinoma occurs in almost one-third of patients with this condition, and it may go unnoticed until metastases occur. Early nephrectomy offers a cure. It is important, therefore, that all patients with optic disc capillary haemangiomata as well as their relatives are referred for screening for the stigmata of this disease.
