ANALYSIS OF CHANGES IN THE ABERRATIONS OF THE OPTICAL SYSTEM OF THE EYE AFTER FEMTOSECOND INTRASTROMAL RING IMPLANTATION OF THE MYORING IN PATIENTS WITH HIGH MYOPIA IN COMBINATION WITH A THIN THICKNESS OF THE CORNEA [№ 12 ' 2015]
Analysis of changes in the aberrations of the optical system of the eye after femtosecond intrastromal Myoring implantation in patients with high myopia in combination with a thin thickness of the cornea. Femtosecond intrastromal Myoring implantation was performed in 43eyes (of 24patients) with an age from24 to 45years (mean of 34.5±3years) with high myopia in combination with a thin cornea thickness. Corneal aberrometry was studied on aberrometer (Visionix L80 WAVE+, Israel) before and 3months after femtosecond intrastromal Myoring implantation. The value of the spherical component of the refraction was from–9.25 to–17.5diopters (average 13.4±1.4diopters), cylindrical from–1.0 to–4.0diopters (average 2.5±1.2d). The minimum value of pachymetry in the centre ranged from430 to 498μm (average of 464μm± 20μm). The average keratometry value— 44.50diopters. The level of higher-order and lower-order aberrations were evaluated. Spherical aberration and Coma aberrations have analyzed from higher-order aberrations. There is analysis of changes in the aberrations of the optical system of the eye after femtosecond intrastromal ring implantation of the MyoRing in patients with high myopia in combination with a thin thickness of the cornea. Uncorrected distance visual acuity (UDVA) has increased in 8times after MyoRing implantation, corrected distance visual acuity (CDVA) — in 1.5times, spherical component decreased in 8.5times, cylindrical — in 2times immediately after surgery. UDVA improved from 0.13±0.01 3months after surgery, CDVA has not changed. Analysis of the results indicates a high refractive efficiency of this method, the reduction of lower-order aberrations and increasing higher-order aberrations. So, analysis of changes in the aberrations of the optical system of the eye after femtosecond intrastromal Myoring implantation in patients with thin cornea during 3months observation showed a reduction of lower-order aberrations and an increase in higher-order aberrations.

SCREENING STUDY OF PERIPHERAL RETINAL DEGENERATIONS AMONG STUDENTS OF HIGHER EDUCATIONAL INSTITUTIONS OF CHELYABINSK [№ 12 ' 2015]
Peripheral retinal degenerations (PRD) are a major cause of rhegmatogenous retinal detachment in young, working persons, both in our country and abroad. The need for preventive measures to prevent complications is dictated by the severity of the disease and the difficulty of its diagnosis and treatment, which underlines the relevance of the study. It was conducted screening eye examination of 23162university students in Chelyabinsk. The average age was 21years old. In 1992people (3012eyes) were revealed different clinical forms PRD. The most frequently encountered white frost degeneration, cystoid, lattice and "snail track". Less detected white without depressions and "cobblestones". Lattice degeneration and "snail track" almost equally often met all kinds of clinical refraction of the eye, including emmetropia. There was both unilateral and bilateral retinal damage. In patients with "cobblestones", white with no depressions, cystoid and white frost degenerations in 60–70% of cases the disease occurred on the background of myopia of high to medium, and often pathological process was bilateral. Thus, by screening younger patients aged 16–25years, the risk-shaped peripheral retinal degenerations occurred in 3.2% of cases in all students and 36.5% of students with PRD, including lattice degeneration 2.4 and 27.5% and the "snail track" of 0.8and 9.0% respectively. The results determine the high importance of preventive medical examinations with obligatory study of the periphery of the fundus of the eye, regardless of the type of refractive error.

CHOROIDAL BLOOD FLOW IN YOUNG PATIENTS WITH PERIPHERAL RETINAL DEGENERATIONS [№ 12 ' 2014]
Retinal degeneration in the periphery is a major cause of rhegmatogenous retinal detachment, resulting in low vision, blindness and disability 2–9% in young adults [4]. It is enough to examine the nature of hemodynamic disturbances in the ophthalmic artery, central retinal artery and short posterior ciliary arteries in young patients with peripheral retinal degeneration [3]. The speed parameters of choroidal blood flow in patients with risk forms of peripheral vitreohorioretinal dystrophies were studied with the help of an integrated ultrasound examination. The speed characteristics and choroidal blood flow pulsator index were significantly low in the projection hearth of lattice and "snail track" degenerations.

CHANGES IN LOCAL HEMODYNAMICS AS A RISK FACTOR OF FORMATION BILATERAL IDIOPATHIC MACULAR RUPTURE [№ 12 ' 2014]
Examined the state of the local ocular hemodynamics and characteristics of choroidal blood flow in patients with idiopathic macular ruptures. Identification of low speed characteristics of choroidal blood flow and blood flow in the short posterior ciliary arteries as in the eye with the IMR, and the pair "health" of the eye, which can be used to predict the course of the disease.

HISTOMORPHOLOGICAL MONITORING OF REPARATIVE ACTIVITY OF GEL 2-(1'-HYDROXI-4'-ISOPROPENIL-1'-METHYLCYCLOGEXIL-2'-TIO)-METYLETANOAT ON THE CORNEA OF EYES OF RABBITS [№ 4 ' 2013]
Histological preparations of corneas of rabbits under the influence of the 2% and 3% gel of 2-(1'-hydroxy-4'-isopropenyl-1'-methylcyclohexyl-2'-thio)-methylethanoate (sulphur containing terpenoid of mentan series) were studied. It is found that the rate of repair processes in the application of 3% gel of sulphur containing terpenoid of mentan series, compared to the data of the control group was higher. The morphological picture of the corneas of rabbits treated with 3% gel of 2-(1'-hydroxy-4'-isopropenyl-1'-methylcyclohexyl-2'-thio)-methylethanoate is identical to the structure of the normal cornea of rabbits.

VITRECTOMY WITH TEMPORAL PFOC ENDOTAMPONADE WITH SILICON OIL SUBSTITUTION IN POSTOPERATIVE ENDOPHTHALMITIS TREATMENT [№ 4 ' 2013]
Tactics of different ethiology endophthalmitis treatment was worked out. Endophthalmitis developed after different surgical interventions. Treatment is carried out in 2 stages. The first stage is partial vitrectomy without epiretinal exudate and posterior hyaloid membrane removal, temporal endotamponade with perftororganic compound (PFOC) finishes the surgery. In 10-14 days the second stage is carried out — revision of vitreal cavity with epiretinal exudate and posterior hyaloid membrane removal, tamponade with silicone oil for 3 months. Such approach allows to maintain visual functions and carry out surgical intervention in spite of poor intraoperative visualization of eye structures.

DEMOGRAPHIC BEHAVIOR CHARACTERISTICS OF FINNO-UGRIC YOUTH [№ 4 ' 2011]
Demographic behavior characteristics of Finno-Ugric youth are studied on the basis of sociological research of Udmurt people and statistical data. The author considers that the alarming orientation on having small number of children is inherent either for Udmurt people or for Russian Finno-Ugric people in common. At the same time the youth has considerable potential for improving the demographic situation.
