Photodynamic Therapy

A light sensitive dye is injected into the blood stream. As the dye travels through the blood vessels to the back of the eye through the blood vessels, a special light is shined into the eye. This activates the dye and causes the abnormal blood vessels to close, shrink, and stop leaking.

This is useful in patients with a naevus or melanoma that is leaking fluid and building up at the back of the eye (macular oedema). Although this is not the main treatment for choroidal melanoma, we may find it useful in some cases where radiotherapy treatment is not possible.
