PHOTODYNAMIC METHOD FOR TREATING CHOROID NEOVASCULAR MEMBRANES

摘要

FIELD: medicine. ^ SUBSTANCE: method involves intravenously introducing photosensibilizer and applying laser radiation. Transpupillary irradiation of choroid neovascular membrane with low intensity laser radiation having wavelength of 633 nm at a dose of 2.5 J and at wavelength of 890 nm at a dose of 1.2 J is applied before intravenously introducing the photosensibilizer. Chlorine row photosensibilizer is intravenously introduced as the photosensibilizer at a dose of 0.5-0.8 mg/kg within 10 min. Transpupillary fluorescent spectral diagnostic of photosensibilizer accumulation in the choroid neovascular membrane is started 1 min later after beginning introducing the photosensibilizer. When detecting choroid neovascular membrane fluorescence in comparison to the surrounding tissues, intravenous laser irradiation of blood is started using wavelength equal to maximum light radiation absorption by the photosensibilizer during 5-15 min at radiation power equal to 20-50 mW. ^ EFFECT: enhanced effectiveness of treatment; dosed treatment procedures; destroyed neoplasm blood vessels and prevented their growth. ^ 3 cl
