Retinal capillary hemangioma.

Capillary hemangiomas of the retina, which commonly occur as part of von Hippel's disease, are classically composed of a retinal capillary tumor, a large feeder arteriole, and a draining venule. The fundamental pathology is a hamartomatous lesion. In this paper, the case of an early, incipient lesion will be presented. Since approximately 25 percent of patients with angiomatosis retinae develop the life-threatening von Hippel-Lindau disease, the eye care practitioner needs to be aware of this condition. Also included in the discussion are the treatment options available for these retinal abnormalities.
