FIELD: medicine. ^ SUBSTANCE: invention relates to medicine, and can be used in ophthalmology for electrochemical lysis and photodynamic therapy of choroidal melanomas (CM). 2 hours after PS introduction on tumour zone on sclera applied and sewn to it is electrode-anode, made in form of net from platinum wire with hole in the centre and corresponding in shape to shape of tumour base projection on sclera, in size being 1 mm smaller than tumour base on entire perimetre; laser light conductor with diffuser, made on entire length of intratumour part of light conductor, is introduced through anode hole into tumour structure transsclerally, with platinum insert-cathode being located on distal end of light conductor; after that, electrochemical lysis of tumour is performed, then by means of laser light conductor intrastromal irradiation of tumour with laser radiation with wavelength, corresponding to maximum of PS absorption of light irradiation, is performed. ^ EFFECT: invention ensures reduction of trauma by electrochemical laser and photodynamic therapy of choroidal melanoma, complete tumour destruction, prevention of metastases. ^ 2 cl, 1 ex |
