[The analysis of application of telemedicine technologies in the Russian Federation in 2019-2022].

Over the past five years, development of telemedicine was accompanied by many changes. Despite the need for remote medical care, development of telemedicine technologies was not uniformly intensive, both in different countries and in regions of a single state (such as Russia). The purpose of the study is to evaluate dynamics of volume of medical care and number of types of services using telemedicine technologies in regions of the Russian Federation.

[Pattern electroretinogram and macular perfusion in glaucoma].

Purpose: To study microcirculatory and functional changes in macula in patients with Primary Open-Angle Glaucoma (POAG).

Material And Methods: The study included 95 POAG patients and 42 healthy control subjects. Whole en face image vessel density (wiVDRetina) was measured both in fovea and in parafovea using OCT-angiography (OCT-A) by means of SD-OCT AngioVue on Avanti RtVue xR (Optovue Inc.

A comparative study of structural, functional and circulatory parameters in glaucoma diagnostics.

Purpose: To compare the diagnostic accuracy of structural parameters, vessel density (VD) measured by optical coherence tomography angiography (OCTA), and electrophysiological testing in diagnosis of primary open-angle glaucoma (POAG).

Methods: 35 healthy participants and 90 POAG subjects underwent the measurement of whole image en face (wi) VD in the disc/peripapillary region and macula, the retinal nerve fiber layer (RNFL), and the average thickness of ganglion cell complex (GCC), pattern electroretinograms and pattern visual evoked potentials. The area under the receiver operating characteristic curve (AUC) was assessed for each parameter to differentiate early POAG from healthy eyes and between the POAG stages.

[Pattern visual evoked potentials and their relation to the peripapillary and retrobulbar blood flow in glaucoma].

Purpose: To examine the relationship between the development of bioelectric response of retinal cell elements to pattern stimulus and the ocular blood flow.

Material And Methods: Electrophysiological studies, including pattern-reversal visual evoked potentials (VEP) with large 1 degree (1°) and small 0.25° checks, Color Doppler imaging (CDI) of the retrobulbar vessels, and OCT Angiography in the area of the optic disc and peripapillary retina were performed in 48 patients with initial primary open-angle glaucoma (POAG), 47 patients with advanced POAG, and 42 control subjects.

Value of Structural and Hemodynamic Parameters for the Early Detection of Primary Open-Angle Glaucoma.

Purpose: To compare the diagnostic value of ocular blood flow parameters and choroidal thickness (CT) with standard structural parameters for early glaucoma detection.

Methods: A total of 32 patients with pre-perimetric glaucoma were compared with 30 age-matched normal subjects. The thickness of the ganglion cell complex (GCC), retinal nerve fiber layer (RNFL), and the choroid and foveal loss volume (FLV) were measured by means of optical coherence tomography (OCT).
