CHRPE is a flat, darkly pigmented spot found in the back of your eye. It can vary in size, ranging from a few to more than 10 mm in diameter. You are born with a CHRPE in the eye, but it may go undetected until much later and is often found as part of a routine dilated eye examination.

The Dangers of CHRPE

While a CHRPE may grow slightly over time, it is not malignant. You very rarely get any noticeable symptoms and it does not pose a risk of spreading to your eyes or risk to your vision.

This is in direct contrast to a choroidal melanoma, which does pose a risk for malignancy and can be dangerous to your vision and overall health. Although CHRPEs and choroidal melanomas may appear similar, it is essential to have a thorough examination at the Annan Retina Eye Center to ensure a correct diagnosis.

CHRPE does not require treatment and can be monitored with repeat dilated eye examinations.
