Nevus
A nevus is typically a flat, benign, pigmented
area that may appear inside the eye or on its surface. Nevi commonly
appear on the choroid (the layer just behind the retina), the iris, and
the conjunctiva. Nevi are similar to freckles, and don't typically
change or grow.
SIGNS AND SYMPTOMS
•Brownish,
freckle-like spot
•Usually flat
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's
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.
