**8. Laser photocoagulation**

Laser photocoagulation is aimed to diminish blood supply of tumor. This type of treatment is used for small (4 mm in diameter and 2 mm in thickness) and posterior tumors. Argon or diode laser or a xenon arc is used but not directly on tumor tissue; instead it is aimed to coagulate the blood vessels that supply the tumor.

Retinal detachment, retinal vascular occlusion, retinal traction, and preretinal fibrosis can be a complication of this type of treatment [61–63].
