Active surveillance for eye cancer

Active surveillance may be a treatment option for some people with eye cancer who are not experiencing symptoms. Active surveillance means the healthcare team watches the cancer closely. Treatment is given when the signs and symptoms of eye cancer appear or change.

Small, slow-growing melanomas in the iris, ciliary body or choroid may not need treatment right away if they appear to be stable. Smaller tumours are less than 2.5 mm (about 0.1 inches) in height (thickness) and less than 10 mm (0.4 inch) in diameter (largest diameter measured at the base of the tumour). Treatment is given if the tumour starts to get bigger and causes vision problems.

Active surveillance is not known to have negative effects or to reduce long-term survival.
