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...

Our aim was to develop quick and exact instrument for examination of color vision defects (CVD). We used Lanthony saturated and desaturated test. Data were evaluated according the Vingrys and King-Smith study. We had together 123 eyes of 86 patients. From all subjects we received these average values: AA 44.32 (min -87.13, max 80.64), TES 13.36 (min 8.84, max 30.30), SI 1.97 (min 1.22, max 5.69) a...

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...

Pupose: To experimentally compare the visual acuity and the subjective perception of different types of multifocal intraocular lenses (IOL) using a VirtIOL device/simulator in a group of volunteers with artephakia. Material and methods: This was an experimental study involving a total of 20 volunteers with artephakia (35 eyes). Each volunteer rated 5 types of IOLs, 4 presbyopia-correcting IOLs - W...

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...

Aim: To evaluate the effect of crosslinking (CXL) therapy on the change in the quality of visual acuity and the change in the topographic properties of the cornea – curvature, pachymetry, and change of astigmatism, coma abberation and CLMIaa (Cone Localisation and Magnitude Index). Methods: A retrospective analytical study included 29 eyes of 24 patients who had progressed in the last 12 months an...

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 ...

In this paper, the authors present a case report of a 46–year–old patient with decompensated pigmentary glaucoma and anterior uveitis after unilateral implantation of a BrightOcular artificial cosmetic iris (Stellar Devices, New York, USA). Postoperatively, there was a decrease of endothelial cells (ECD) down to 1216 cells/mm2, a uveal reaction in the anterior chamber and a significant decompensat...

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 ...
