METHOD OF LASER TREATMENT OF FOCAL DIABETIC MACULAR EDEMA

摘要

FIELD: medicine.;SUBSTANCE: invention relates to the field of medicine, namely, to ophthalmology, and can be used to treat focal diabetic macular edema. Determine the localization of edema from optical coherence tomography (OCT) and the area of dye transudation from fluorescent angiography (FAG) data. Throughout the zone of edema and transudation, laser action is performed in the micropulse mode in a selective range of energy parameters. Laser applications are applied at a distance of one diameter of the applicator from each other. Outside the foveal avascular zone, the effect is performed with parameters: wavelength of the yellow spectrum, the duration of the micropulse is 50–100 mcs, the duty cycle is 0.5–4.7 %, the power is 0.5–2.0 W, the spot diameter is 50–150 mcm, number of pulses in the packet 1–20. In the foveal avascular zone, the effect is performed with parameters: wavelength of the yellow spectrum, the duration of the micropulse is 50–80 mcs, the duty cycle is 0.5–2.5 %, the power is 0.8–2.0 W, the spot diameter is 80–130 mcm, the amount pulses in the packet 1–10.;EFFECT: method provides for the reduction of solid exudates and hemorrhages, reduction of retinal thickness, disappearance of cysts, restoration of retinal architectonics according to OCT, reduction of exudation according to FAG, reduction of unreasonable prolonged use of drugs, reduction of the risk of formation of epiretinal fibrosis and refractory macular edema, risk of irreversible reduction of visual functions, as well as the lack of scotoms, areas with reduced photosensitivity, chorioretinal atrophy focus in the zones of laser treatment due to a high degree of absorption by the pigment epithelium of the yellow spectrum of laser radiation and a selective increase in temperature in the cells of the pigment epithelium.;1 cl, 2 ex
