Abstract

Malignant melanomas of the choroid have been treated successfully by two different procedures: photovaporization and photoradiation. Photovaporization involves use of the carbon dioxide laser beam to vaporized choroidal malignant melanomas directly within the eye after the vitreous has been removed completely and replaced with medical- grade N gas. A delicate N flow system keeps the intraocular cannula of the carbon dioxide laser open during photovaporization. This procedure is used for large intraocular malignancies.
