Choroidal Neovascularization Associated with Rare Entities

Abstract

Choroidal nevi are usually found incidentally during routine ophthalmoscopic examination. The prevalence ranges from 4 to 8% in general white population [1,2] making it the most common benign melanocytic intraocular tumor in adults [3]. Clinically, choroidal nevi appear as flat or slightly elevated, round or oval pigmented gray-brown (and sometimes amelanotic) lesions with well-defined margins. They are located deep to the retina, evenly distributed in all four quadrants of fundus and more common in postequatorial region [4].Although mostly asymptomatic, choroidal nevi should be observed for possible malignant transformation [5]. They may result in decreased visual acuity by inducing secondary changes in overlying retinal pigment epithelium (RPE) and retina including RPE atrophy or secondary fibrous metaplasia, pigment epi-
