In rare cases, a nevus on the outer wall of the eye affecting the eye’s appearance may be removed with surgery.
Your ophthalmologist will not endanger your eye by removing a harmless nevus inside the eye. However, all nevi should be examined regularly by your ophthalmologist. This is how they can detect changes that could mean the nevus is becoming cancerous.
Every time you visit your ophthalmologist, your nevus should be examined to compare it to earlier photographs. Any changes in the size or shape of the nevus means it needs to be examined more closely. New photographs will be taken every few years or anytime your doctor sees a change.
