A Case of Treatment of Macular Subretinal Neovascularization with the Red-Light Krypton Laser

ABSTRACT

A case of macular subretinal neovascular membrane was treated by red-light krypton photocoagulation. We used continuous red-light krypton laser(647.1nm) because this light is not absorbed by the hemoglobin in the retinal hemorrhage or by the macular luteal pigment(Xanthophyll). 3 weeks after treatment there was no specific change in the treated area. 6 weeks later, we found that the treated area showed some regression of subretinal neovascular membrane. After 3 monthes, the destruction of the subretinal neovascular membrane was complete, and the visual acuity was improved.
