    What are the symptoms of Intraocular (Uveal) Melanoma ?
    ### Response:
    Signs of intraocular melanoma include blurred vision or a dark spot on the iris. Intraocular melanoma may not cause early signs or symptoms. It is sometimes found during a regular eye exam when the doctor dilates the pupil and looks into the eye. Signs and symptoms may be caused by intraocular melanoma or by other conditions.
