[Optical coherence tomography and optical coherence tomography-angiography in the diagnosis of chiasmo-sellar region compression].

Unlabelled: Preservation of visual functions in patients with chiasmo-sellar region compression (CSRC) is possible with early diagnosis and surgical decompression.

Purpose: To analyze the parameters of optical coherence tomography (OCT) and optical coherence tomography-angiography (OCTA) in patients with CSRC.

Material And Methods: The study included 10 patients (20 eyes) with CSRC, 15 healthy volunteers (30 eyes).

Molecular genetic mechanisms of influence of laser radiation with 577 nm wavelength in a microimpulse mode on the condition of the retina.

The Aim Of The Study: was to investigate the molecular genetic mechanisms of the influence of laser radiation with 577 nm wavelength in a microimpulse mode on the retina in the experimental conditions after the intravitreal injection of VEGF.

Materials And Methods: The study was performed on 4-5 week-old male mice of the line C57BL/6J. The animals were divided into 4 groups of 5 mice in each group, one eye was excremental, the contralateral eye remained intact.

[Structurally-functional status of heart of the tuberculosis in teenagers].

The patients divided into two groups: in 12 patients (13-16 years old) including into I group observed decrease of internal size of the left ventricle, in 8 persons (17-18 year old) revealed the elevation of internal size of the cavity of the left ventricle. From the analysis of results of the observations it is seen that, in patients including into 1 group the thickness of the wall of the left ventricle is higher than the internal size of the ventricular cavity. This time, the main aim of hypertrophy is the compensation of the increase of 2R/T thickening the wall of the left ventricle and decrease of the internal size of the ventricular cavity happened.

[Modern data regarding the cardiovascular system lesions in patients with bronchopulmonary diseases and tuberculosis].

The article presents literature review on modern data regarding cardiovascular system lesions in patients with bronchopulmonary diseases and tuberculosis. To detect these changes is of great importance for an assessment of a functional condition of an organism as a whole.

[Study of visual perception under conditions of extreme light exposures].

Neurophysiological processes of transduction and analysis of information concerning brightness of photostimuli and peculiarities of functioning of visual system under exposure to extra-bright light effects or extreme contrasting of visual objects are studied poorly and present significant interest for unraveling actual mechanisms of visual perception under extreme conditions. Conducting analysis of visual system in maximal broad range both in terms of adequate perception and reflection of light stimulus intensity and adaptive mechanisms to extra-strong illumination regimes is as well very important. The to-date obtained data indicate that under the extreme light effects pathology of the peripheral portion of visual analysator can be induced.
