Most nevi do not require treatment, and it is generally not advised to surgically remove a nevus. In rare cases when a nevus is located on the outer wall of the eye and has become a significant cosmetic problem, surgery may be possible. A nevus that is located further inside the eye would likely never be removed because of danger to the eye. However, all nevi should be examined at least once a year by your Eye M.D. in order to detect changes that could signal a risk of the nevus becoming cancerous.
During each visit to your Eye M.D., the nevus should be photographed to compare it to previous photographs. Any changes in the size or configuration of the nevus require additional examination.
