Overview
PET scan, ultrasound biomicroscopy, optical coherence tomography, color fundus photography, fluorescein angiography, indocyanine green angiography, transillumination, and photography may be helpful in the diagnosis of uveal melanoma.
Other Imaging Findings
PET scan, ultrasound biomicroscopy, optical coherence tomography, color fundus photography, fluorescein angiography, indocyanine green angiography, transillumination, and photography may be helpful in the diagnosis of uveal melanoma.[1]
Positron Emission Tomography Scan
- A baseline PET scan of the liver and other abdominal organs is recommended in patients with a uveal melanoma. Tumors that are too small will be identified by this study.[2]
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).[5]
Color fundus photography
- Color fundus photography photographs of the fundus helps to show whether the tumor looks the same as before treatment or not.
Fluorescein angiography
- Fluorescein angiography is a procedure to look at blood vessels inside the eye.[6]
Indocyanine green angiography
- Indocyanine green angiography is a procedure to look at blood vessels in the choroid layer of the eye. [7]
Transillumination
- Transillumination is an exam of the iris, cornea, lens, and ciliary body with a light placed on either the upper or lower lid. [8]
- We may see the tumor as a dark shadow with well-defined margins.
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.
