To assess the effect of adequate laser coagulation (LC) of peripheral vitreochorioretinal dystrophy (PVCRD) on the clinical and functional state of the retina and the microcirculation of the macular region. Material and methods. Ganzfeld electroretinogram (ERG), multifocal ERG (mfERG), and optical coherent tomography with a function of angiography (OCTA) were performed for the retina of 22 patients (37 eyes), aged 20 to 62, who had been given an adequate volume of LC to treat dangerous types of PVCRD. The tests took place before LC and 1, 3, 6, 9, 12 months after it. To analyze the results, two groups were formed: (1) 27 eyes with LC volume of less than 200 coagulates and (2) 10 eyes with LC volume of more than 200 coagulates. Results. After LC, we observed a moderate decrease in the amplitudes of scotopic ERGs and the a-wavepeak latency lengthening in the maximal ERG. In the 2 ndsubgroup, the amplitude of the second wave of oscillatory potentials (OP2) and the OP index decreased more significantly than in the 1st, subgroup (by 17 and 21 % from the initial values, respectively, p |
