How do you get rid of enlarged, or large gathering of blood vessels in the eye safely?

Exam first: The primary goal is to determine why there is an enlarged or engorged group of vessels on the eye. Is there an underlying tumor with a sentinel feeding vessel or is there a pterygium? If no cause is found and the blood vessels are unsightly, excision with cautery usually proves to be successful.

Cause?: These should be examined first. Could be some sort of hemangioma, sentinel vessel leading to a cancer, increased episcleral venous pressure, infection, inflammation, allergy, etc.
