Overview

Other imaging studies of uveal melanoma include ultrasound biomicroscopy, optical coherence tomography, color fundus photography, fluorescein angiography, indocyanine green angiography, transillumination, and photography.

Other Imaging Findings

Ultrasound biomicroscopy

Ultrasound biomicroscopy is a special type of ultrasound that uses sound waves at even higher frequency than ultrasound to image the front parts of the eye.

Optical coherence tomography

Optical coherence tomography is a test that uses light waves instead of sound waves to create very detailed images of the back of the eye (fundus).

Color fundus photography

With color fundus photography photographs of the fundus are taken, that help to show what the tumor looks like before and after treatment.

Fluorescein angiography

Fluorescein angiography lets the doctor see the blood vessels inside the eye. Although melanomas don’t have a special appearance with fluorescein angiography, some other eye problems do. Doctors can use this method to tell if something is not a melanoma.

Indocyanine green angiography

Indocyanine green angiography is a procedure to look at blood vessels in the choroid layer of the eye.

Transillumination

Transillumination is an exam of the iris, cornea, lens, and ciliary body with a light placed on either the upper or lower lid. This procedure is used to examine eye structures for any gross abnormality.

Photography

High resolution digital cameras are used to take pictures of the inside and outside of the eye and to view the structures in the back and front of the eye. These photographs are important for documenting the tumor and its relationship to important structures of the eye. By comparing photographs before and after treatment, they can help determine whether the treatment given is effective.
