A
nevus is typically a flat, benign, pigmented area that appear inside the eye or
on its surface. Nevi commonly appear on the choroid, the iris, and the
conjunctiva. Nevi are similar to freckles, and don't typically
grow. It usually does not cause any visual symptom either.
Detection and Diagnosis
Nevi
of the conjunctiva or iris can be detected with a slit lamp microscope. If the
nevus occurs within the eye, it is evaluated with an ophthalmoscope.
Treatment
Nevi
are usually harmless, but it is always wise to monitor them for changes. This
can be done with photos and sometimes ultrasound. The doctor will document the
size, shape and whether the nevus is elevated. In rare cases, the nevus must be
biopsied and examined for melanoma (cancer) cells.
