Choroidal Nevus

Choroidal nevi are commonly found in the choroid, a blood vessel-rich layer lying between the retina and the sclera. Although they are not necessarily a “normal” finding in our eyes, they are quite common and may not represent anything wrong with the eye. Choroidal nevi are present in about 6% of eyes. Nevi vary from patient to patient but most look very similar and have certain traits that eye doctors are very familiar with. Choroidal nevi are not usually harmful. However, just like a freckle on your skin, it should be monitored for changes in color, size or shape. Typical treatment involves taking a digital photograph for documentation.

 

A choroidal nevus is the name given to a spot, freckle or mole that appears inside the eye.

Choriodal nevi are benign, however, we want to watch closely for the rare development of a choroidal melanoma, a tumor found in the eye. It is estimated that about 1 in 8000 of choroidaI nevi will transform into melanomas. Choroidal melanomas are malignant tumors and due to their aggresive nature that can sometimes result in death, they must be treated early.
