A nevus is typically a flat, benign, pigmented area that may appear inside the eye or on its surface
If we suspect an ocular condition or disease,
we will immediately schedule or perform
diagnostic tests to determined our next steps.
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.
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.
