Organ-on-chip is a microfluidic device that can reproduce the minimal functional unit of an organ or system of organs and model various physiological processes and body structures with high accuracy. This review covers the main approaches to the use of the organ-on-chip technology in modern experimental ophthalmology. The analysis of literature sources revealed the following main applications of the organ-on-chip technology in ophthalmology; the technology allows modeling the anterior eye surface and its diseases, such as dry eye syndrome, as well as disorders of the posterior segment of the eye such as age-related macular degeneration, diabetic macular edema, diabetic retinopathy, glaucoma. Culturing of eye tissues in microfluidic systems helps identify the toxic effects and pharmacological activity of new compounds, and provides an opportunity for deeper understanding of the normal physiology of the eye and the pathogenesis of ocular diseases. In addition, the technology can reduce the cost and duration of experiments. Thus, the organ-on-a-chip technology has a great potential in the field of experimental ophthalmology and preclinical trials of new ophthalmic drugs.

Purpose: This study aimed to analyze demographic, clinical, socioeconomic, and facility-specific factors affecting the survival outcomes of patients diagnosed with eyelid melanoma (EM) between 2004 and 2017 using data from the National Cancer Database.
Methods: Cases of EM diagnosed between 2004 and 2017 were identified using the National Cancer Database. Patient demographic data, tumor stage (American Joint Committee on Cancer TNM classification), treatment modalities, and socioeconomic variables were collected.

Purpose: Autologous retinal transplantation has been successfully employed in the treatment of large and myopic macular holes that are refractory to standard surgical treatments. Patients transplanted with a peripheral neurosensory retinal graft have shown unexpected improvements in visual acuity. The study aims to investigate if neural integration of the graft takes place in a porcine model of retinal hole.

Background: Diabetic retinopathy (DR) is a common complication of diabetes, which may cause visual disturbance and even loss of sight. Oxidative stress and inflammation are two crucial pathological factors of DR; however, their specific regulatory mechanisms in DR remain obscure.
Methods: DR models were established in streptozotocin-challenged rats and high glucose (HG)-stimulated Müller cells.

Mechanisms of anion permeation within ion channels and nanopores remain poorly understood. Recent cryo-electron microscopy structures of the human bestrophin 1 Cl channel (hBest1) provide an opportunity to evaluate ion interactions predicted by molecular dynamics (MD) simulations against experimental observations. Here, we implement the fully polarizable force field AMOEBA in MD simulations on different conformations of hBest1.

The present study aimed to investigate the causal relationships among cognitive impairment, psychopathology, and real-life functioning in a large sample of people with schizophrenia, using a data-driven causal discovery procedure based on partial ancestral graphs (PAGs). This method may provide additional insights for the identification of potential therapeutic targets to promote recovery in people with chronic schizophrenia. State-of-the-art instruments were used to assess the study variables.
