METHOD FOR PHOTODYNAMIC THERAPY OF PROLIFERATIVE DIABETIC RETINOPATHY Russian patent published in 2012 - IPC A61F9/08 A61N5/67 A61K31/409 A61P43/00 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely ophthalmology. A method involves introducing a photosensitiser (PS) in a patient's body that is followed by retinal exposure to laser light. Chlorine photosensitiser 0.4-0.5 mg/kg is intravenously injected for 10 minutes. Immediately after the PS introduction, ischemic areas and retinal neovascularisation areas are exposed to transpupillary laser light. That is ensured by laser light at wave length matched to maximum PS adsorption of optical emission. Power density makes 50-75 J/cm².

EFFECT: method provides the absence of damaging action on the surrounding functional retinal areas, the absence of hemorrhagic complications and developing exudative retinal detachment, stabilises proliferative diabetic retinopathy and enables conducting the whole therapeutic volume for one session ensured by graduated retinal exposure to laser light that covers ischemic areas and retinal neovascularisation areas.
