A choroidal nevus (or benign neoplasm of the choroid) is a grayish-brown pigmented lesion with slightly blurred margins. Naevus of Ota (naevus fusculocoeruleus ophthalmomaxillaris) was described by the Japanese dermatologist, Ota, in 1939 as a dermal melanocytic hamartoma that presents as bluish hyperpigmentation along the ophthalmic, maxillary, and mandibular branches of the trigeminal nerve. It is bilateral in less than 5% cases, occurring frequently in Orientals Pigmented Retinal Lesions & Choroidal Nevus The retina sits on top of two pigmented layers that line the inside of the eye. These pigmented layers are called the retinal pigment epithelium and the choroid. These two layers contain a pigment called melanin, which is common to other parts of the body, such as the skin. Sometimes they are found on the front of the eye near the iris and other times they are in the back of the eye near the retina. A nevus can be congenital which means that it is present at birth or it can develop during early childhood.

Areas of retinal pigment epithelial (RPE) hypertrophy usually do not cause symptoms. They are typically found during routine eye examinations. Congenital retinal pigment epithelial Congenital hypertrophy of the retinal pigment epithelium (CHRPE) is a typically benign, asymptomatic, pigmented fundus lesion. It is a congenital hamartoma of the retinal pigment epithelium (RPE) and occurs in three variant forms: solitary (unifocal), grouped (multifocal) and atypical.

A typical choroidal naevus is asymp-tomatic, less than 5mm in diameter and less than 1mm in thickness, with surface drusen, no orange pigment (lipofuscin), not in direct contact with the disc and not associated with any sub-retinal fluid. A retina specialist is often asked to evaluate anything suspicious in the retina, especially when a tumor is suspected. The nevus is actually a collection of pigmented cells. The nevus is usually grey or perhaps brown in color and does not usually cause any symptoms.
