Under the retina is a pigmented layer called the choroid. This layer is very rich in blood vessels, and is pigmented. The pigment in this layer is the same as in our skin. A choroidal nevus is a growth that arises from pigmented cells in the choroid. These are typically benign and are relatively common.

Melanocytic Nevus of the Caruncle. This pigmented lesion of the caruncle is elevated due to small cysts (similar to lesions in the conjunctiva) with varying brownish pigmentation. Since pigmented lesions of the caruncle carry a risk of developing into a melanoma they should be observed regularly for potential growth.

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.

In 1943, Ackermann and Field reported the first case of oral nevus. retina: see vision vision, physiological sense of sight by which the form, color, size, movements, and distance of objects are perceived. Vision in Humans The human eye functions somewhat like a camera; that is, it receives and focuses light upon a photosensitive receiver, the retina. Objective: To describe the optical coherence tomography (OCT) findings of choroidal nevi. Methods: Retrospective, single-center case series of 120 eyes of 120 consecutive patients with choroidal nevi who were evaluated by OCT. Diagnostic imaging was performed with a Zeiss StratusOCT Model 3000 (Carl Zeiss Ophthalmic Systems, Dublin, CA) using scan acquisition protocols of 6 radial lines and 2019-04-04 2012-05-01 A choroidal nevus is like a mole in the back part of the eye, in a layer called the choroid, which is located behind the retina.

giant congenital pigmented nevus (giant hairy nevus) (giant pigmented nevus) any of a group of large, darkly pigmented hairy nevi, usually bilaterally symmetrical and present at birth; the most common locations are the chest, upper back, shoulders, arms, legs, and or hip and groin area.These nevi are associated with other cutaneous and subcutaneous lesions, as well as neurofibromatosis and retina: see vision vision, physiological sense of sight by which the form, color, size, movements, and distance of objects are perceived.

Choroidal nevi and choroidal melanoma can show several overlapping features, including tumor size; color, which may be either pigmented or nonpigmented; location; associated dormant features, such as overlying retinal pigment epithelial alterations and drusen; and suspicious features, including subretinal fluid and orange pigment. Nevus appeared orange red on MCI and its size appeared larger than the same measured on conventional CFP. We also report infrared reflectance and near infrared autofluorescence features of choroidal nevus.
