Modern view on the problem of optic neuritis (systematic review)

Summary:

The review discusses modern concepts of etiopathogenesis, clinic, diagnosis, treatment and preventive measures for optical neuritis, as well as the position of modern ophthalmology on the principles of management of patients with optical neuritis of various etiologies. The review includes 14 sources over the past 25 years from Russian (Elibrary CyberLeninka) and international (PubMed) databases.

SD-OCTA parameters of the optic disk and peri papillary retina in older age group

Year: 2020, volume 16 Issue: №1 Pages: 265-268

Summary:

The purpose of the study is to investigate the optic disk and peripapillary retina parameters using SD-OCTA in people of an older age group. Material and Methods. 31 patients (62 eyes), 12 males and 19 females, mean age 57.1 ±9.6 were examined. All patients underwent SD-OCT and SD-OCTA examination (RTVue XR, Optovue), by using protocol HD Angio Disk 4.5*4.5 mm. SD-OCT and SD-OCTA were used to measure the radial peripapillary capillaries (RPC, %) and retinal nerve fiber layer thickness (RNFL, urn), rim area, disc area, cup volume. Results. Mean value of the RNFL thickness was 109.7±11.1 urn. 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. Conclusion. The reference values of the optic disk and peripapillary retina parameters for senior Russian citizens, which were developed with RTVue XR Avanti (Optovue Inc., USA) device, can be used as diagnostic criteria for neuroophthalmological pathology.
