Aim of the study was to evaluate retrospectively selected parameters, which influence the postoperative near visual acuity in a group of pseudophakic eyes of patients with Uncorrected Distance Visual Acuity (UDVA) and according to acquired results establish those, which mostly influenced good Uncorrected Near Visual Acuity (UNVA) after the implantation of monofocal IntraOcular Lens (IOL). Altogeth...

The objective of the study was to determine whether there exists a difference in the central cornea thickness (CCT) in patients with hypertensive (HTG) and normotensive glaucoma (NTG), and subsequently, to compare the application of prostaglandins by corrected CCT (CCT correction) for both types of glaucoma. Material and methods: 100 eyes of 50 patients (the average age of 67) with HTG and 100 eye...

The study provides an up-to-date overview of pathogenesis, functional and structural changes in normal tension glaucoma (NTG) and its differences from high tension glaucomas (HTG). The authors point to less known facts which make both diagnostic groups different. First of all, there are electrophysiological findings that verify pathology in the complete visual pathway in HTG in contrast to NTG whe...

The objective of this study was a retrospective assessment of two-year experience with micropulse cyclophotocoagulation (MP CPC) in the therapy of various types of glaucoma. Material and method: The cohort of patients consisted of 47 people, out of which 16 men and 31 women. An average age of males was 58.9 years (the range from 35 to 78 years), and an average age of females was 64.7 years (the ra...

Purpose: The purpose of the study was to evaluate influence of betaxolol, brimonidine and carteolol in the progression of the visual field defects during time at patients with normotensive glaucoma (NTG). Materials and methods: This study included (60 eyes of) 30 patients with NTG. First group consisted of 20 eyes of 10 patients of the average age of 58.5 years, who were treated by betaxolol. Seco...

Purpose: The aim of our study was to find out whether in patients with hypertensive glaucoma (HTG) and normotensive glaucoma (NTG), there is a change in the size of the chiasm depending on the changes in the visual field. Therefore, we retrospectively measured the width of the chiasm in the patients to whom we measured the size of the corpus geniculatum laterale in 2013. Materials and methods: The...

Aims: To investigate the dependence of blood vessel density and velocity in ophthalmic artery and arteria centralis retinae of the same eye in patients with normotensive glaucoma. Methods: The sample consisted of 20 patients with normotensive glaucoma (NTG). There were 17 women (mean age 56.1) and 3 men (mean age 60 years). Inclusion criteria for study: visual acuity 1.0 with correction up to ±3 d...

Aims: The aim of the work is to point out the transmission of electrical voltage changes in the visual analyser and thus the efficiency of the bionic eye. Material and methods: The review deals with the question of the transmission of electrical changes in visual path voltage under physiological and pathological conditions. In particular, it points to feedback autoregulatory damage not only of pri...

The paper presents the up-to-date overview of pathogenesis, functional and structural changes in normotensive glaucoma (NTG) and its differences from hypertensive glaucoma (HTG). The autors point out new facts that distinguish both diagnostic groups. In the first place are the results of OCT angiography, which verify the pathology of NTG to the anterior part of optic nerve. Our findings confirmed ...

Purpose: The purpose of the study was to evaluate the visual functions after implantation of Acrysof monofocal intraocular lenses Alcon (SA60AT. MA50BM a SN60WF a SN6AT). Materials and methods: Four works are presented in the overview. The first work deals with the effect of eye length. corneal optic power and anterior chamber depth on the uncorrected near visual acuity (UNVA) after IOL implantati...

Aim: The aim of the study was to determine the morphological and functional findings in a patient after methanol poisoning. Examination methods: The patient (male, 38 years old) was suffered methanol poisoning in eight years ago (2012). The following tests and examinations were performed: neurological visual field XR test (Medmont M700), retinal nerve fibre layer (RNFL), ganglion cell complex (GCC...

Aims: The aim of the work is to verify the necessity of full-field perimetry test in incipient glaucoma. Material and methods: The study included group of 16 incipient hypertension glaucoma (HTG group) patients without obvious changes in visual field and control group of 10 patients with normal ocular findings and value 1.0 of visual acuity. In both groups, full-field perimetry test was performed ...

Aims: The main aim of this work was to find out if there is a correlation between vessel density (VD) and results of measured perfusion values in ophthalmic artery and in central retinal artery of the same eye in a group with hypertension glaucoma (HTG). Materials and methods: The file included 20 patients with HTG, thereof 13 women of average age 68.7 years (49–80 years) and 7 men of average age ...

The aim of this study was to establish, if there exists the difference between Ganglion Cell Complex (GCL) and the Retinal Nerve Fiber Layer (RNFL) measurements in the same altitudinal half of the eye in hyper-tension (HTG) and normal-tension glaucomas (NTG). Materials and Methods: We examined both eyes in altogether 50 patients (100 eyes). The cohort was divided into two groups, in each of them; ...

Aim: To determine, if in the group of hypertensive (HTG) and normal-tension glaucomas exists correlation among ganglion cell complex (GCC) and retinal nerve fiber layer (RNFL) in the same altitudinal half of the retina and sum of sensitivities of the visual field’s opposite half (hemifield test) of the same eye. Materials and methods: In the HTG group, there were 25 patients; thereof 12 women of t...

Aim: The aim of the study was to determine whether hypertensive glaucoma (HTG) with different types of treatment leads to significant damage in any of the evaluated parameters. Sample and methodology: The sample, consisting of 36 HTG patients (72 eyes), was divided into three subgroups: In the first group, patients were treated with combination therapy (latanoprost + timolol, latanoprost + dorzola...

Aims: The aim of the study was to determine the limits of the far nasal part of the visual field. Material and Methods: Visual field examination was performed in 15 healthy subjects (30 eyes), specifically nine women aged 20–43 years and six men aged 22–35 years. All eyes were found to have physiological ocular findings and visual acuity of 1.0 with correction less than or equal to 3 diopters. The...
