Choroidal Nevus - Peripapillary

You should look at the Normal Retina photo first for comparison. Sometimes a choroidal nevus arises adjacent to the optic disk, as can be seen in this case of a large nevus. It is also possible for pigmented nevus cells to be located in the neural rim of the optic disk, as is seen here. Yearly photographs of a lesion such as this allows accurate determination of any signs of growth. In the rare case of growth, and a determination that the lesion had become a melanoma, it would be difficult to use an eye sparing therapy such as a radioactive I125 plaque. A peripapillary melanoma is usually treated with surgical removal of the eye (enucleation).
