Low-energy long-exposure laser therapy in the management of choroidal melanoma.

Low-energy (0.2-0.4 W) long-exposure (10-30 s) argon green and krypton red laser applications were used in the treatment of 29 selected choroidal melanomas. In 11 cases laser treatment was the only therapy used. In 18 cases laser was used as an adjunct to local surgical resection of the tumour. The technique gives promise of being useful in the management of relatively flat choroidal melanomas of up 4 mm in thickness.
