The pattern electroretinogram (PERG)-according to ISCEV method (using DTC contact electrodes, reference electrode was placed on the skin near the ipsilateral outer canthus of each eye, the size of the stimulating area was 15 degrees, the reversal rate of the squares equal to 0.8 degrees and the contrast equal to 80%) was bilaterally normal (Fig. 2).
Vessel density of RPC in November 2021 (above) and its decline in August 2022 (below). RE, right eye; LE, left eye; RPC, radial peripapillary capillaries.

The examination was performed on the Avanti RTVue XR by Optovue (USA), see results in Fig. 3.
Magnetic resonance imaging, 3D FLAIR, axial reconstruction (TR/TE 4,800/269 ms). Small focuses of non-specific gliosis in the white matter of both cerebral hemispheres. (a) Hyperintense FLAIR foci in paraventricular region on the left and in the insular region on the right (arrows). (b) Multiple punctate foci of gliosis in the subcortical white matter (arrows). FLAIR, fluid-attenuated inversion recovery.
