#COLORDIAL NEVUS SERIAL#

1 By comparison, choroidal melanoma is rare, manifesting in approximately six in 1 million Caucasian individuals.

In the United States, their prevalence ranges from 4.6 percent to 7.9 percent in Caucasians.

Ophthalmic examination follow-up with serial fundus photography, ultrasonography or fluorescein angiography. Choroidal nevi are benign melanocytic lesions of the posterior uvea.A choroidal nevus refers specifically to a mark that forms in the choroid, a layer of the eye behind the retina. Just like these marks can occur on your skin, they can also appear on parts of your eye. A-scan may have some value in diagnosing elevated lesions. What is a choroidal nevus A choroidal nevus (plural: nevi) is similar to a birthmark or mole that occurs inside of the eye.Based on several studies, the overall prevalence of choroidal nevus in the adult population.

Deep-setting nevi that spare choriocapillaris will give relatively normal fluorescent Choroidal nevus is the most common primary intraocular tumor.

Thicker nevi with overlying drusen will be hyperfluorescent.

When the nevi encroaches or replaces part of the choriocapillaris, the lesions may appear hypofluorescence.

Choroidal nevi are relatively common and occur in approximately 6.5 of the Caucasian population and about 3-4 of the general population. Melanocytes are melanin (pigment) producing cells located in the choroid layer of the back of the eye.

Deeply pigmented nevi will be relatively hypofluorescent, while less pigmented are tend to be hyperfluorescent A choroidal nevus is essentially a benign tumor of the choroid composed of melanocytes.

Angiographic features will vary depend on the degree of pigmentation.

Choroidal neovascularization membrane associated with exudation or hemorrhage may develop.

May be surrounded by a yellowish ring (halo nevus).

Geographic patches of orange pigment may overlie the nevi, but may also be an early sign of a malignant transformation of the lesion.

Commonly associated with overlying Bruch's membrane changes, drusen depositions, RPE clumping or migration, serous detachment of the sensory retina or the RPE.

Dark gray - brownish pigmented, flat or minimally elevated lesion with slightly well demarcated margin, which size is mostly not greater than a disc diameter.

Benign choroidal developmental tumors that composed of melanocytes.
