FIELD: medicine.
SUBSTANCE: 3 months after the photodynamic therapy, the fluorescent angiography is applied in the patient. The angiography is analysed in an advanced venous phase in a program used to calculate the fluorescence brightness of a choroidal neovascular membrane (CNVM) and the fluorescence brightness of a balanced CNVM site of an intact eye-ground. The CNVM fluorescence intensity factor which represents a relation of the average brightness of a CNVM nidus to that of the intact eye-ground is calculated. If the CNVM fluorescence intensity factor is less than or equal to one, photodynamic therapy is considered to be effective.
EFFECT: method allows for objective estimation of clinical effectiveness of PDT in choroidal neovascularisation based on the quantitative analysis of the fluorescent angiography data.
