Purpose: To investigate whether diurnal changes in biometric parameters at different times of the day are visible and to analyze whether the variations could have clinical significance in the process of intraocular lens (IOL) power calculation.
Methods: Phakic eyes measured by IOLMaster 700 above the age of 16 were included, with the exclusion of previous surgery. Measurements were taken between 7:00 and 15:00 and data were treated in hourly groups within this range.
The role of spirituality in health and disease is a complex and emerging area of research. Incorporating spirituality into the bio-psycho-social model of health and disease leading to the bio-psycho-social-spiritual model provides a more comprehensive framework. In this context, chronic disorders like primary Sjögren's syndrome (pSS) are of interest due to their intricate interactions between biological, psychological, and spiritual factors.

Allergic inflammations mainly affect the conjunctiva, causing acute and/or chronic conjunctivitis. Several forms are distinguished: seasonal allergic conjunctivitis, vernal conjunctivitis, atopic keratoconjunctivitis, contact allergy, giant papillary conjunctivitis.

Among human transplantation, keratoplasty is the most successful surgical procedure. In recent decades, penetrating keratoplasties have been increasingly replaced by lamellar techniques, where only the abnormal layer of the cornea is transplanted.

Moreover, neurological complaints precede the sicca symptoms in 25-60% of the cases. We review the magnetic resonance imaging (MRI) lesions typical for pSS, involving the conventional examination, volumetric and morphometric studies, diffusion tensor imaging (DTI) and resting-state fMRI.

Materials and methods: Histological specimens of corneal buttons removed during keratoplasty were investigated in PBK (n = 20) and FECD (n = 9) and compared to healthy control corneas (n = 10). The sections were studied by chromogenic immunohistochemistry (CHR-IHC) and submitted for evaluation by two investigators.

Patients And Methods: In our cross-sectional study, patients with monoclonal gammopathy (130 eyes of 65 patients (40.
Semi-quantitative scoring is a method that is widely used to estimate the quantity of proteins on chromogen-labelled immunohistochemical (IHC) tissue sections. However, it suffers from several disadvantages, including its lack of objectivity and the fact that it is a time-consuming process. Our aim was to test a recently established artificial intelligence (AI)-aided digital image analysis platform, Pathronus, and to compare it to conventional scoring by five observers on chromogenic IHC-stained slides belonging to three experimental groups.

During PD progression, microglia, the resident immune cells in the central nervous system (CNS) display altered activity, but their role in maintaining PD development has remained unclear to date. The purinergic P2Y-receptor (P2YR), which is expressed on the microglia in the CNS has been shown to regulate microglial activity and responses; however, the function of the P2YR in PD is unknown.

These pathological conditions include bullous keratopathy (BK), Fuchs' endothelial corneal dystrophy (FECD), and corneal scarring in herpetic keratitis.
Methods: Histological sections of corneal buttons removed during keratoplasty were analyzed in BK (n = 20), FECD (n = 9), herpetic keratitis (n = 12), and cadaveric control (n = 10) groups with light microscopy following chromogenic immunohistochemistry.
Purpose: To assess the accuracy of the intraocular lens (IOL) power calculation based on three methods using artificial intelligence (AI) and one formula using no AI.
Methods: During cataract surgery on 114 eyes, one type of IOL was implanted, calculated with the Hill-RBF 2.0 method.
Dementia with Lewy bodies (DLB) and Parkinson's disease dementia (PDD) are two major neurodegenerative diseases sharing common clinical, pathophysiological and morphologic features. The pathological hallmark of both diseases is the presence of Lewy-bodies (LB). The main constituent of these inclusions is the pathologically aggregated α-synuclein protein.

Setting: Borsod-Abaúj-Zemplén County Central Hospital and University Teaching Hospital, Miskolc, Hungary.
Design: Evaluation of diagnostic technologies.
Introduction And Aim: To present our results on femtosecond laser-assisted penetrating keratoplasty.
Patients And Method: Twenty-five eyes of 25 patients underwent surgery with the following indications: pseudophakic bullous keratopathy (n = 10), keratoconus (n = 4), corneal dystrophy (n = 5), corneal scar (n = 4), band keratopathy (n = 2). Trephination of both the donor and recipient corneas were performed with VisuMax femtosecond laser device (Carl Zeiss Meditec AG, Jena, Germany).
Aim: To evaluate the anterior and posterior corneal surfaces using scanning-slit topography and to determine the diagnostic ability of the measured corneal parameters in keratoconus.
Methods: Orbscan II measurements were taken in 39 keratoconic corneas previously diagnosed by corneal topography and in 39 healthy eyes. The central minimum, maximum, and astigmatic simulated keratometry (K) and anterior axial power values were determined.

We summarize up-to-date diagnostic and treatment of infectious keratitis using literature data and some clinical examples. In the clinical practice, most commonly bacterial, herpetic, mycotic and acanthamoeba keratitis occur. Beside slitlamp examination, for diagnostic purpose, we analyse corneal sensitivity, perform in vivo confocal microscopy, polymerase-chain-reaction (PCR), in vitro culture and histological examination of the corneal sample.
