Abstract
AbstractPurposeTo investigate the OCTA parameters of the peripapillary retina and optic disk in Caucasian people of an older age groupMethodsThirty‐four patients (68 eyes), 14 male and 20 female, mean age 57.1 ± 9.6 were examine. All patients underwent OCT and OCTA examination (RTVue‐XR, Optovue), by using protocol ‘HD Angio Disk’ 4.5*4.5 mm. OCT and OCTA were used to measure the radial peripapillary capillaries (RPC, %) and retinal nerve fiber layer thickness (RNFL, µm), rim area, disc area, cup volume.ResultsMean value of the RNFL thickness was 109.7 ± 11.1 µm. The lower value of the RNFL thickness was observed in ‘Tempo Inferior’ and ‘Tempo Superior’ segments. Rim area was 1.66 ± 0.33 mm2, disc area—1.87 ± 0.28 mm2. The mean value of RPC density in peripapillary retina was 52.2 ± 2.3%. The lower value of the RPC density was in ‘Nasal Inferior’ and ‘Superior Nasal’ segments, 48.9 ± 3.2% and 49.9 ± 3.1%, respectively.
