SURGICAL METHOD FOR APPLYING PHOTODYNAMIC TREATMENT TO PREMATURE NEWBORN RETINOPATHY Russian patent published in 2005 - IPC

FIELD: medicine.

SUBSTANCE: method involves applying trans-scleral laser radiation to avascular zones and cushion. Size and location of avascular zones and cushion are transpupillarily determined. Conjunctiva and Tenon's capsule incision is carried out in perpendicular to limb 2-3 mm far from it. Pocket is formed with spatula in parallel to limb in avascular zones and cushion projection area. Photosensibilizer agent is intravenously introduced into one of cubital veins and avascular zones and cushion photosensibilizer agent saturation degree is determined by applying photodynamic fluorescent diagnosis method. Maximum avascular zones and cushion saturation level being achieved, trans-scleral scanning laser radiation is applied to the avascular zones and cushion projection area with wavelength of 661-666 nm during 60-120 s with radiation dose being equal to 40-80 J/cm². The operation is finished without placing sutures over conjunctiva.

EFFECT: enhanced effectiveness of treatment.
