Nevus is the medical term for a birthmark. Just as freckles, moles, and birthmarks can occur on your skin, a nevus can also be found inside your eye. They are most often seen in the pigmented layer beneath the retina called the choroid. A choroidal nevus can only be seen by an eye care specialist using specialized tools to see inside your eye.

A choroidal nevus is a growth that arises from pigmented cells in the choroid. These are typically benign and are relatively common. The choroid is the layer around the back part of the eye between the retina and the sclera. The choroid tissue has the highest concentration of blood flow in the body.

Several pigmented lesions of the ocular fundus can be detected on routine ophthalmic examination. Pigmented tumoral lesions, both benign and malignant, can arise from the retinal pigment epithelium or from choroidal melanocytes. A careful evaluation of the clinical and imaging features can help to differentiate the lesions, avoiding diagnostic errors. 2014-07-08 Choroidal Nevus Just as freckles, moles, and birthmarks can occur on your skin, a nevus (the medical term for a birthmark) can also be found inside your eye.

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.

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 Under the retina is a pigmented layer called the choroid. This layer is very rich in blood vessels, and is pigmented.

Learn more about Choroidal Nevus. Is a choroidal nevus dangerous? Most choroidal nevi remain benign and We present data of the right eye of a 59-year-old gentleman with choroidal nevus who underwent conventional CFP as well as MCI. 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. 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.

The cutaneous halo nevus, also known as Sutton nevus or nevus depigmentosa centrifugum, appears as a pigmented nevus surrounded by a halo of depigmentation. 1 This phenomenon can also be found with cutaneous melanoma and metastasis. 2 The cutaneous halo nevus is most often found in children and young adults, with a prevalence rate of approximately 1%, and can be multiple in a simultaneous or

The patient continues to be followed with a stable giant choroidal nevus. DISCUSSION Choroidal nevus is a benign melanocytic lesion, appearing pigmented or non-pigmented, and classically less than 2 mm in thickness. 1 Although uncommon, malignant transformation of choroidal nevi into melanoma is possible. 2017-12-11 A congenital nevus, also known as a mole, is a type of pigmented birthmark that appears at birth or during a baby’s first year. These occur in 1% to 2% of the population. These moles are frequently found on the trunk or limbs, although they can appear anywhere on the body. A congenital hypertrophy of the retinal pigment epithelium (CHRPE) is a flat, pigmented spot within the outer layer of the retina at the back of the eye.
