Purpose. Study the thickness of periapillary retina, ganglion cell complex and optic disc parameters in patients with nonarteritised anterior ischemic optic neuropathy using the spectral OCT angiography. Material and Methods. We examined 17 people (17 eyes) with unilateral non-arteritised anterior ischemic optic neuropathy (no more than 30 days from the appearance of complaints), the average age was 64.1±8.1 years. The control group consisted of 37 volunteers. All the subjects were treated with spectral OCT angiography on RTVue XR Avanti device (Optovue Inc., USA). Results. In patients with non-arteritised anterior ischemic optic neuropathy, compared to the control group, there was a statistically significant increase in the average thickness of periapillary retina nerve fiber layer from 136 to 403 µm, an increase in optic disc area and neuroretinal belt (p < 0.0001) and the absence of cupping (Cup Volume = 0). A decrease in average thickness of ganglion cell complex was found in 8 out of 17 patients, while all patients showed increases in FLV (p=0.008) and GLV (p=0.036). A direct correlation relationship between FLV (r=0.64; p<0.05) and GLV (r=0.51; p<0.05) was found, as well as a moderate negative correlation relationship between uncorrected visual acuity (r=-0.58; p<0,05), moderate direct correlation relationship between average thickness of periapillary retina nerve fiber layer and thickness of ganglion cell complex (r=0.68; p<0,05), and high inverse correlation relationship between FLV (r=-0.77; p<0,05) and GLV (r=-0.76; p<0,05). Conclusion. A comprehensive analysis of thickness of periapillary retina nerve fiber layer and parameters of ganglion cell complex using spectral OCT angiography may allow for a more accurate detection of early retinal structural abnormalities and the timely commencement of conservative therapy to preserve functional parameters. Key words: spectral OCT angiography, anterior ischemic optic neuropathy, ganglion cell complex, optic disc.

PurposeTo 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.

The relevance of assessing the lesion of the visual analyzer with optic disc drusen and the possibility of identifying concomitant pathologies, increases with the introduction of the latest diagnostic techniques.In the S. Fyodorov Eye Microsurgery Federal State Institution, Moscow, a patient, 50 years old, complaining of episodic blurred vision. The diagnosis revealed the drusen of the optic nerve head and concomitant congenital neurological pathology. The patient was consulted by a neurosurgeon with the aim of delivering a diagnosis and determining treatment tactics. The diagnosis was made: Arteriovenous malformation of the deep arteries of the sections of the left parietal lobe. After assessing the size of the arteriovenous malformation, its location in the functionally important area of the brain, it was decided to follow up the patient in dynamics

Обзор литературы посвящен исследованиям заднего отдела глаза у больных с кератоконусом. Описаны аномалии развития диска зрительного нерва и изменения в макулярной области при этой патологии, а также при сочетании кератоконуса с оптическим невритом, выявленные с помощью оптической когерентной томографии, лазерной томографии, электрофизиологических исследований. Проблема недостаточно решена, и публикации немногочисленны в связи с тем, что у пациентов с кератоконусом сложно визуализировать глазное дно из-за высоких ошибок рефракции и астигматизма роговицы, это затрудняет оценку изменений глазного дна. Ключевые слова: кератоконус, оптическая когерентная томография, диск зрительного нерва, лазерная томография.
