Choroidal Hemangioma

Introduction:

Choroidal hemangiomas are benign vascular tumors that present in two distinct forms:

▶ Solitary (circumscribed)

The solitary lesions are most commonly an isolated finding, while the diffuse form is rare and typically associated with Sturge–Weber syndrome.

Clinical Features:

They may be identified as an incidental finding, but can affect visual acuity if there is associated subretinal fluid or cystic fluid involving the macula. Typical features include a reddish/orange coloration and location in the posterior pole (Fig. 21.3.1). RPE metaplasia on the surface is not rare. Occasionally, clinical findings are subtle and they are only identified on OCT.
