Objective: Although the eyes occupy 0.1% of the total body surface, eye injuries are serious because vision is arguably the most important sense. We aimed to assess knowledge of Saudi Arabian residents regarding steps to be taken in cases of chemical eye injury, in order to promote awareness of such procedures.
Results: A cross-sectional design was done. A random sampling method was utilized to select 888 individuals in the Saudi community. Participants completed an electronic closed ended, validated, anonymous, self-administered questionnaire. Two experts assessed content and face validity. Respondents were 18-29 years of age. 74 (8.3%) had a history of chemical eye injury. Regarding the first step taken in case of chemical eye injury, 697 (78.5%) respondents indicated washing with water, 164 (18.5%) indicated visiting the emergency department, 11 (1.2%) indicated using eye drops, and 5 (0.6%) indicated covering the eye immediately. Seventy-five (8.4%) respondents agreed that an eye injured with an acidic material should be washed with an alkaline solution. These results should be confirmed by health authorities and appropriate interventions should be developed for improving knowledge among masses, thereby promoting a healthier society.

Background/aims: To identify the risk factors for neuropathic corneal pain (NCP) following corneal refractive surgery and to report its clinical manifestations, imaging and proteomic characteristics.
Methods: This 1 year prospective cohort study included 100 eyes that underwent small incision lenticule extraction (SMILE) or laser-assisted in situ keratomileusis (LASIK). Ocular surface assessments, in-vivo confocal microscopy scans, tear neuromediators and proteomics analyses were performed.

Wearable sensors have broad application potential in motion assessment, health monitoring, and medical diagnosis. However, relying on a specialized instrument for power supply and signal reading makes sensors unsuitable for on-site detection. To solve this problem, a reusable self-powered electrochromic sensor patch based on enzymatic biofuel cells were constructed to realize the on-site visualized monitoring.

Glaucoma is an irreversible, progressive, degenerative eye disorder arising because of increased intraocular pressure, resulting in eventual vision loss if untreated. The QSPR relates, mathematically, by employing various algorithms, a specified property of a molecule that arises either from physical, chemical, or biological phenomena using various aspects of its structure. Here in, a similar application based on topological indices and inferences derived from the structure for the calculation of different drug properties like molar refractivity, refractive index, enthalpy, boiling points, molecular weight, and polarizability is presented.

Due to its anatomical and physiological similarities to the human eye, the porcine eye serves as a robust model for biomedical research and ocular toxicity assessment. An air/liquid corneal culture system using porcine eyes was developed, and ex vivo epithelial wound healing was utilized as a critical parameter for these studies. Fresh pig corneas were processed for organ culture, with or without epithelial wounding.

Glaucoma, a leading cause of blindness, demands innovative and effective treatments that surpass the limitations of current drug and surgical interventions to lower intraocular pressure. This study describes the generation of cell-repellent hydrogel patches, their deposition on the ocular surface, and a photoinduced chemical binding between the patches and the collagens of the eye. The hydrophilic and protein-repellent hydrogel patch is composed of a copolymer made from dimethylacrylamide and a comonomer unit with anthraquinone moieties.
