Eye tumors are often first noticed during routine exams
Uveal melanoma manifests itself in many ways. Some people may experience blurred vision, floaters, flashing lights and shadow in the vision. For many others, however, there is no sign of irregular vision and the tumor may go undetected until it is found during a routine dilated eye exam.
To check for abnormalities and make a diagnosis, the doctor uses an indirect ophthalmoscope to examine the back part of the inside of the eye. Your doctor may also use ultrasound, fundus photography, fluorescein angiography, or even a biopsy, to establish the diagnosis. However, uveal melanoma is one of the few cancers that can be accurately diagnosed without a biopsy in most cases.
