Choroidal Nevus

Choroidal nevus is the most common intraocular tumor, occurring in about seven percent of adults. Most patients have no symptoms and these lesions are discovered on routine eye examination. Although it may be congenital, choroidal nevus is not typically observed in small children. It usually is first detected in adulthood and can be flat or minimally elevated and pigmented or nonpigmented (amelanotic). 

The diagnosis of choroidal nevus is made by an experienced eye doctor using indirect ophthalmoscopy and with the help of tests such as ultrasonography, photographic imaging and ocular coherence tomography. Choroidal nevus carries a slight potential to evolve into melanoma, so these lesions need to be continually monitored for any signs of change.
