[Three-component tear substitute as preoperative support in glaucoma surgery].

Purpose: This study investigates the effect of preoperative preparation with the three-component tear substitute Stillavit on the outcomes of glaucoma surgery in patients on long-term topical glaucoma therapy.

Material And Methods: The study included 63 patients (63 eyes) with glaucoma, among them 30 (30 eyes) were women and 33 (33 eyes) were men. Group 1 consisted of 33 patients (33 eyes) receiving long-term topical antihypertensive therapy with preservatives and tear substitute Stillavit 3 times a day for 1 month as preoperative preparation.

[Studying the condition of filtering bleb after glaucoma surgery using optical coherence tomography].

Purpose: To compare the optical coherence tomography (OCT) findings on the condition of filtering bleb (FB) in patients with primary open-angle glaucoma (POAG) who used different local therapy before glaucoma surgery.

Material And Methods: The study included a total of 82 patients (82 eyes) followed up after glaucoma surgery: 50 patients (50 eyes) who received preservatives-containing drugs before glaucoma surgery; 32 patients (32 eyes) - who were on preservative-free drug treatment before glaucoma surgery. The examinations were carried out 7 days, 1 and 3 months after micro-invasive sinus trabeculectomy.

[Methods of assessing the condition of filtering bleb after glaucoma surgery].

Currently, there is a need to assess the condition of structures at the surgery site after glaucoma intervention due to the necessity to decide further treatment tactics after performed operations, as well as the possibility of developing more advanced methods of surgical treatment of glaucoma. Despite the fact that there are several methods of examining the filtration bleb (FB), some of them have both clear advantages and significant disadvantages. This article reviews the possibilities of using optical coherence tomography (OCT), ultrasound biomicroscopy (UBM), thermography, confocal microscopy, and the Hyperemia-3 program for assessing the structural and functional state of the FB.

[Persistent hyaloid artery in an adult (a case report)].

The article presents a clinical case of a functioning hyaloid artery in a 69-year-old patient. The results of OCT-angiography made it possible to detect the presence of blood flow in the projection of the persistent hyaloid artery (PHA) on the cross-section and en-face images. The vascular bed of PHA spreading along the posterior surface of the lens in the form of separate branches was visualized by slit-lamp biomicroscopy.

[Effects of artificial tears on ocular surface in glaucomatous patients with long-term instillation of preserved antiglaucoma eye drops].

Purpose: To study the effects of long-term instillation of 0.18% sodium hyaluronate artificial tears VISMED multi on ocular surface in glaucomatous patients with long-term instillation of preserved anti-glaucoma drops.

Material And Methods: The study included 79 patients (40 female and 39 male; 79 eyes in total) with primary open-angle glaucoma (POAG) divided into 3 groups according to disease stage: mild or early (stage I) glaucoma - 15 patients (15 eyes), moderate (stage II) glaucoma - 30 patients (30 eyes), advanced or severe (stage III) glaucoma - 34 patients (34 eyes).

[A case of progressive glaucoma against the background of chronic constipation].

The authors describe a case of severe glaucoma in the only seeing eye of a patient with venous circulation disturbance resulting from a chronic anal fissure complicated with progressive anal stenosis, severe sphincter spasm, and pain syndrome. The article presents the results of multiple clinical ophthalmological tests and instrumental examinations performed before and after surgical intervention that evidence the importance of venous circulation disturbances for glaucoma development.

[Changes in biomechanical properties of the ocular fibrous tunic in patients with primary open-angle glaucoma in response to drug-induced stress-relief tests].

Aim: To determine the effect of drug-induced stress-relief tests on biomechanical properties of the ocular fibrous tunic in eyes with early, moderate, or advanced primary open-angle glaucoma (POAG).

Material And Methods: A total of 202 eyes of 150 patients with POAG of different severity (early, moderate, or advanced) and 36 eyes of 30 healthy controls were examined. The mean patient age was 62±8.

[Application of Retinalamin for the treatment of glaucomatous optic neuropathy].

A case of Retinalamin (peptide-based drug) use in a patient with newly diagnosed glaucoma and therapeutically normalized intraocular pressure is reported. The results of visual field test (Humphrey Field Analyzer) and optic nerve examination (Heidelberg Retina Tomograph) as well as electrophysiological indices before and 1 and 3 month after the course of Retinalamin (10 parabulbar injections) are presented.

[Hemodynamic changes in myopia of different degrees].

A total of 78 patients (143 eyes) with low, medium and high degree myopia were assessed. Apart from standard ophthalmological tests, flowmetry and duplex ultrasound of ocular vessels were performed in all cases to evaluate volumetric and velocity parameters of ocular blood flow in relation to the length of anterior-posterior axis and the degree of myopia. It is found that both parameters of regional blood flow progressively decrease as the anterior-posterior axis increases.

[Effect of vasoactive drugs on visual functions and ocular hemodynamics in patients with primary open-angle glaucoma].

The effect of cavinton forte on visual functions and ocular hemodynamics was studied in patients with primary open-angle glaucoma (POAG). Fifty-three patients (97 eyes) aged 45 to 75 years (mean age 66.3 +/- 3.

[Relationship of changes in visual functions and optic disk in patients with glaucoma concurrent with myopia].

Forty-nine myopic patients (70 eyes) aged 2 to 12 years (mean 7 +/- 4.2 years) with primary open-angle glaucoma (POAG) were examined. In patients with glaucoma concurrent with myopia, enlarged peripapillary retinal atrophy is one of the first signs of a progressive process, long optical axis in particular.

[A comparative analysis of hemodynamic parameters within the evaluation of the glaucomatous process in patients with myopia].

One hundred and eighty (180) persons (363 eyes), mean age 63.7 +/- 5.2, mean follow-up--6.

[Use of xalatan in unstable glaucoma in myopic patients].

41 patients (79 eyes), their age averaged 66.9 +/- 4.5 years were divided into two groups.

[The efficacy of the antioxidant preparation Histochrome in the treatment of hemophthalmos in hypertension and diabetes mellitus].

Hemophthalmos in patients with essential hypertension and diabetes mellitus was treated by antioxidant agent Histochrome manufactured by the Pacific Institute of Bioorganic Chemistry, Far Eastern Division of Academy of Sciences, Vladivostok. The results were analyzed with reference to localization, volume, and period elapsed since hemorrhage into the vitreous body and by hemophthalmos index determined by biomicroscopy and echography of the vitreous body. Histochrome was the most effective in fresh hemophthalmos with 1-2 point index.

[The antioxidant activity of the lacrimal fluid in patients with primary open-angle glaucoma].

Antioxidant activity (AOA) of lacrimal fluid and blood plasma was studied in 10 normal subjects (20 eyes) and 35 patients with primary open-angle glaucoma (POAG) (67 eyes with glaucoma at different stages). The findings indicate that the progress of glaucoma is paralleled by a gradual decrease in the lacrimal fluid AOA, which becomes significant at the third stage of POAG. Plasma AOA also decreased significantly in the third far advanced stage.

[Antioxidative activity of histochrome and some other drugs used in ophthalmology].

The antioxidative activity (AOA) of histochrome (2,3,5,6,8-pentahydroxy-7-ethyl-1,4-naphthoquinone) and some other drugs with antioxidant properties used in ophthalmology has been studied in the hemoglobin--hydrogen peroxide--luminol system. The AOA of histochrome, ascorbate, dicinon, rutin, quercetin, and dihydroquercetin is comparable to that of trolox, the reference antioxidant in our studies. The drugs (in physiological concentrations) listed above are characterized by a high AOA.

The effect of radial keratotomy on contrast sensitivity.

In the period after surgical correction of myopia and astigmatism in 30 patients (44 eyes) by radial keratotomy, contrast sensitivity deteriorated slightly. The disturbances, however, were transitory, and the general trend was toward restoration of function. Strict adherence to an adequate operative technique prevented a marked decline in contrast sensitivity.
