The effect of retinal perfusion on the bioelectric activity of the retina in full-thickness macular holes

BACKGROUND: Information on retinal capillary perfusion in idiopathic full-thickness macular hole (FTMH) is limited, and there are no data the possible effect of blood supply to individual areas layers retina their functional activity.
 AIM: To study relationship between vascular superficial deep plexuses (SCP DCP) bioelectrical activity hole.
 MATERIALS AND METHODS: Multifocal electroretinography (mfERG), optical coherence tomography (OCT), OCT-angiography (OCTA) were performed 18 eyes with FTMH 10 intact eyes. In projection hexagons mfERG pattern, parameters compared structural changes (hole, cystic changes), density SCP DCP.
 RESULTS: group, capillaries correlated P1 implicit time R2 ring (R = 0.23, p 0.05), zone intraretinal 0.21 R 0.22, amplitude 0.24, 0.05). plexuses, N1 at fixation point 0.57 0.19, 0.2, R3 rings 0.46 0.44, more pronounced 0.54 0.29, 0.05).
 CONCLUSIONS: There a correlation different its FTMH. A decrease plexus macula chronic may be predictor low prognosis outcome surgical treatment
