Choroidal nevus (plural: nevi) is a type of eye neoplasm that is classified under choroidal tumors as a type of benign (non-cancerous) melanocytic tumor.[1] A choroidal nevus can be described as an unambiguous pigmented blue or green-gray choroidal lesion, found at the front of the eye, around the iris,[2] or the rear end of the eye.[3][4]
Nevi are usually darkly pigmented tumors because they comprise melanocytes. Dr. Gass, one of the leading specialists on eye diseases, speculates that a choroidal nevus grows from small cells resting as hyperplastic lesions, and exhibits growth primarily.[5] In most cases, choroidal nevus is an asymptomatic disease, however, in serious conditions, adverse symptoms can be observed.
Choroidal nevus is usually diagnosed through an ophthalmic eye examination, or more specialized technologies such as photographic imaging, ophthalmoscopy, ultrasonography and ocular coherence tomography (OCT). Choroidal nevi can transform into a choroidal or ocular melanoma, becoming cancerous. Therefore, it is crucial to differentiate between a non-cancerous choroidal nevus and lethal melanoma.
