FIELD: medicine.
SUBSTANCE: invention relates to medicine, namely to ophthalmology. Optical coherence tomography (OCT) is performed in order to determine the height of macular edema (ME) and draw up a topographic map. Then, a color photograph of the fundus is taken on a Navilas 577s navigation laser system (NLS) using built-in software. Digital images of OCT and fluorescent angiography (FAG) are superimposed and compared with a color photograph of the fundus obtained on the Navilas 577s NLS, and a scheme for applying laser applications is drawn up with a choice of a pattern consisting of three to five applications on a digital image of the fundus. After that, in an automatic mode, laser exposure is carried out throughout the entire area of MO and extravasation by applying laser applications in the form of patterns in the range of energy parameters depending on the height of the ME according to the topographic map according to OCT data. In the foveal avascular zone (FAZ), a micropulse laser action is carried out with the following parameters: the duration of the micropulse is 50-70 microns, the interval between pulses is 2000 microns, the duty cycle is 2.4-3.4%, 5 pulses per packet, the spot diameter is 100 microns, power - 0.8-1.9 W, wavelength - 577 nm with an interval of 0.5 spot diameter between the applicators. Outside the FAZ and ME height less than 300 microns, a micropulse laser action is carried out with the following parameters: micropulse duration - 80-100 microns, pulse interval - 2000 microns, duty cycle - 3.8-4.8%, 5 pulses per packet, spot diameter - 100 microns, power - 0.8-1.9 W, wavelength - 577 nm with an interval of 0.5 spot diameter between the applications. Outside the FAZ and a ME height of more than 300 microns, laser coagulation is carried out, with the parameters: spot diameter - 100 microns, pulse duration - 0.05-0.1 s, power - 100-240 mW, wavelength - 577 nm with an interval of 2 spot diameters between applications.
EFFECT: invention allows achieving complete resorption of MO with preservation or improvement of central visual functions.
