FIELD: medicine.
SUBSTANCE: invention relates to medicine, oncology, and can be used for photodynamic tumour treatment. For this purpose photosensitiser (PS) of chlorine line is introduced intravenously by drop infusion during 10 minutes in dose 0.8 mg/kg of body weight. 10 minutes after finishing PS introduction, retina is irradiated transpupillarly by laser radiation with wavelength corresponding to maximum of absorption of light radiation by PS with energy density 40-50 J/cm2. Irradiation is performed concentrically from zone of vascular arcades to utmost periphery by fields with 4 mm diametre with covering 5% of area of adjacent fields. Next day preparation ranimizumab is introduced to patient intravitreally in dose 0.5 mg.
EFFECT: method allows to provide impediment for development of neovascularisation of eye anterior segment with complete organic blockade of anterior chamber angle and further intraocular pressure decompensation, reduces risk of development of inflammatory complications after laser impact on retina.
