Our aim in this study was to prove influence of chromagen filter on color vision quality. Further we wanted to compare quality of color vision in groups of young healthy persons with persons with maculopathy. In our study we had in total 39 subjects. First group contained 13 subjects with average age 23 years without important eye pathology. In the second group we had 13 patients (average age 68 y...

Purpose: To evaluate OCT findings and long-term follow-up results in patient with optic disc pit (ODP) and associated maculopathy treated with pars plana vitrectomy (PPV). Methods: Six eyes of 6 patients (3 females, 3 males) were included in a retrospective study. We excluded patients with ODP without maculopathy. Patients were followed in years 2008-2017. Mean age at the first examination was 40,...

The main goal of our study was to prove short-term objective influence of near addition and relieving prism on accommodative and vergence facility in group of young healthy persons. Further, we wanted to prove objective and subjective difference between two types of soft contact lenses during working with digital device. We had in total 37 subjects in our study. The first group contained 37 subjec...

The study examines the sensitivity and specificity of spectral OCT in detecting early glaucoma. The aim was to evaluate data obtained by RNFL analysis in 4 observed quadrants and to compare it with the resulting diagnosis of glaucoma neuropathy determined subsequently on the basis of changes in the visual field. This concerns a retrospective study numbering 31 probands who underwent OCT examinatio...

Purpose: We usually use objective and subjective methods for examination of the eye astigmatism in optometry, respectively ophthalmology. Objective methods enable to measure sphere-cylindrical refraction of the eye. If we want to prescribe new glasses or contact lenses we usually use subjective methods. The aim of this study was to measure sensitivity and specificity of some subjective and objecti...

Aims: Metamorphopsia is important symptom of macular disease. The most common simple detection method of metamorphopsia is Amsler grid. Usually it is used monocularly with best correction for near. Patient should evaluate grid deformation and describe position of the deformity. This method is based on qualitative principle. For quantitative evaluation we can use Software D Chart (Thomson Software ...

Aims: The main aim of our study was to demonstrate the difference in endothelial cell density between a group of keratoconus contact lens users and non-contact lens users (without keratoconus). Material and methods: In our study we had data from 96 subjects with an average age of 40.5 ±14.05 years. For the purposes of our study, we worked with each eye separately for each subject (n = 192). Kerato...

Aims: To demonstrate changes in distance and near fusional vergence measured with prism bars, while compensating for present heterophoria using current ametropia correction. In addition, to determine the differences in values of the AC/A ratio determined by the heterophoric (calculation) and gradient methods. Material and methods: The basic sample includes 19 subjects with a mean age of 21.5 ±3.0 ...

Aims: To demonstrate the relationship of dependency between the thickness of the retinal nerve fiber layer and the functional sensitivity of the retina in healthy young individuals. We also secondarily investigated the relationship between refractive error and mean retinal thickness in the macula. Material and methods: The basic cohort contained 30 subjects with an average age of 23.4 ±4.2 years. ...

This study follows the occurrence of refractive errors in population and the possible selection of the appropriate type of corrective aids. Objective measurement and subsequent determination of the subjective refraction of the eye is an essential act in opotmetric practice. The file represented by 615 patients (1230 eyes) is divided according to the refractive error of myopia, hyperopia and as a c...

Aims: To confirm current knowledge about the causes of refractive errors in adults. To evaluate the influence of systemic, i.e., primary curvature and, on the other hand, axial causes of refractive errors of the eye, in comparison with the Gullstrand model of the eye expressed by axial length and corneal curvature ratio. Material and Methods: The basic sample included 60 eyes of 30 subjects with a...

Purpose: To evaluate obtained data by using a relatively novel devices and their results which are important eg. in refractive and cataract surgery. Material and methods: The study included 66 eyes (n = 66). Subjects were represented by 32 women and 1 man whose age was 22.5 years ± 1.2 years (min. 21, max. 26 years) without any signs of potential eye disease. Duration of the study was 3 months. Re...

Aim of the paper is to introduce and evaluate the microperimetry as a support technique in the evaluation of the ARMD wet form bevacizumab (Avastin) treatment efficacy. Methods: Twenty-one patients (21 eyes) with ARMD wet form were included in the study; they were examined by means by OCT/SLO (optic coherence tomography / scanning laser ophthalmoscope) machine whose part is the microperimetric tes...
