Choroidal/Iris/Ciliary Body Nevus

About Choroidal/Iris/Ciliary Body Nevus

A Nevus is a benign growth of cells that develops in the eye, most commonly in the part of the eye called the choroid. The choroid is a layer behind the retina of blood vessels and pigmented tissue that brings oxygen and nutrients to the eye. In this region, a cluster of cells can grow called a nevus that has the potential to evolve into an aggressive cancer called melanoma. Other locations include the iris the colored part of the eye and the ciliary body the area behind the iris.


Columbia ophthalmologists can discover a nevus during a routine eye exam. If one appears, our ophthalmologist will take a picture of the nevus to track any changes in its appearance from visit to visit, or additional testing may be needed, which includes:

  • Ultrasound – An imaging test in which high-energy sound waves (ultrasound) are bounced off the internal tissues of the eye to create an image of the inside of the eye.
  • Fluorescein Angiography – A examination of the blood vessels and blood flow inside the eye.
  • Ocular Coherence Tomography – An imaging test that uses light waves to detect swelling or fluid beneath the retina.

Treatments We Offer

Most choroidal nevi do not require treatment, but our ophthalmologists will photograph them at each visit and compare the new image to any previous ones. Changes in the size or shape of a nevus may suggest early malignancy and require special treatment.
