Purpose: Large part of the population suffers of some kind of refractive errors. It is supposed that their prevalence could change with the development of the society. The aim of this study is to determine the prevalence of refractive errors using calculations based on the Gullstrand schematic eye. Methods: We used Gullstrand schematic eye to calculate refraction retrospectively. Refraction was pr...

Purpose: functioal and anatomical results afer combinationof intravitreal dexamethasone implant with anti-VGF bevacizumab in macular edema secondary to retinal ein occlusion. Methods: Retrospectie analysis of 50 patints, average age 72 years, 15 men and 35 women. Inclusion criteria for treatment were retinalvein occlusion, best corrected visual acuity (BCVA) more than 20/200 and macular edema more...

Purpose: To analyze refractive results after cataract surgery in relation to used type of monofocal intraocular lens, calculation formula, to age, gender and laterality. Settings: Department of Ophthalmology, Comenius University and University hospital in Bratislava, Slovakia Methods: We analyzed 173 eyes (118 patients) after uneventful cataract surgery. We calculated prediction error (PE) and mea...

The aim of the work is to approach the examination of the pupil with a focus on anisocoria, its characteristics and approach to the diagnosis of pupillotonia and Adie's syndrome and its clinical evaluation. Pupil function is important not only in neurophthalmological examination but also in general ophthalmological examination. First of all, we need to know how the reflex arc works in order to be ...

Aims: To analyse the changes in endothelial cell density (ECD) after pars plana vitrectomy (PPV) and to identify the factors implicated.  Patients and Methods: This was a prospective, consecutive, and non-randomised, case-control study. All 23-gauge vitrectomies were performed by a single surgeon at a tertiary centre. ECD was measured at baseline before surgery and on postoperative Days 30, 90, an...

In December 2019, a novel coronavirus (CoV) epidemic, caused by the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) emerged from China. Coronaviruses belong to enveloped ssRNA viruses and are classified into four genera: Alpha coronavirus, Beta coronavirus, Gamma coronavirus and Delta coronavirus. It is assumed that SARS-CoV-2 is spread primarily during a personal contact via bigger r...

Aim: Case report of choroidal neovascularization (CNV) detection in patient who was treated for bilateral retinoblastoma in early childhood. Material and methods: Patient at 1.5 years of age treated for endophytic retinoblastoma stage 4 (according to the Reese-Ellsworth classification) bilaterally, with a positive mutation in the Rb1 gene. After undergoing bilateral retinal laser treatment and 6 c...

Aims: To analyze changes in surgically induced corneal astigmatism and artificial intraocular lens (IOL) stability over time following cataract surgery. To compare the interchangeability of measurements between an automatic keratorefractometer (AKRM) and a biometer. Material and methods: In this prospective observational study, the above-mentioned parameters were collected from 25 eyes (25 subject...

Aim: To introduce the topic of pediatric keratoconus, highlighting the importance of routine corneal topography and tomography in children and adolescents from predisposed groups. To attempt to ensure the early detection of keratoconus and its subclinical form, enabling early treatment, which brings better expected postoperative results. Material and methods: Using the corneal tomograph Pentacam A...

Aim: To clarify the possibilities and role of posterior segment imaging in patients with neurofibromatosis type I (NF1), and to show the prevalence of this disease in the pediatric population in Slovakia. Material and methods: Until recently, ophthalmologic consultations in patients with NF1 were limited mainly to the observation of Lisch nodules of the iris and the presence of optic nerve glioma....
