Glaucoma is a leading cause of irreversible blindness. A genome-wide search yielded multiple single-nucleotide polymorphisms (SNPs) in the 15q24.1 region associated with glaucoma. Further investigation revealed that the association is confined to exfoliation glaucoma (XFG). Two nonsynonymous SNPs in exon 1 of the gene LOXL1 explain the association, and the data suggest that they confer risk of XFG mainly through exfoliation syndrome (XFS). About 25% of the general population is homozygous for the highest-risk haplotype, and their risk of suffering from XFG is more than 100 times that of individuals carrying only low-risk haplotypes. The population-attributable risk is more than 99%. The product of LOXL1 catalyzes the formation of elastin fibers found to be a major component of the lesions in XFG.

Background: The aim of the present study was to compare the rates of change in Ganglion Cell- Inner Plexiform Layer (GCIPL) and Retinal Nerve Fiber Layer (RNFL) thickness, as measured by Optical Coherence Tomography (OCT) Guided Progression Analysis (GPA) program in control group, Primary Open Angle Glaucoma (POAG) and Pseudoexfoliation Glaucoma (PXG) eyes.
Methods: 60 POAG and 60 PXG patients and 30 control group patients were included in the study. Patients diagnosed with glaucoma were divided into two groups as mild (Mean deviation (MD) > -6.

To examine ultrastructural changes in the trabecular meshwork (TM) in patients with primary and secondary glaucoma using scanning electron microscopy (SEM). This was a qualitative descriptive hospital-based study on the ultrastructure of the TM. Pure TM samples were collected after microincisional trabeculectomy from 26 patients with primary or secondary glaucoma and 10 control samples from eye bank donor corneas.

Purpose: This study aims to analyze the outcomes of cases of abandoned cataract surgeries referred to a tertiary eye center.
Methods: This retrospective observational case series includes eleven cases referred to a tertiary eye center following abandoned cataract surgeries. The preoperative factors, intraoperative management, and postoperative outcomes were recorded and analyzed.

Purpose: To investigate the role of hematological and atherogenic biomarkers in evaluating systemic inflammation and cardiovascular risk in patients with pseudoexfoliation syndrome.
Methods: This retrospective study included 200 patients, 90 with pseudoexfoliation (PEX) syndrome (Group 1) and 110 healthy controls (Group 2). Twelve-hour fasting blood samples were collected to measure complete blood count, neutrophil/lymphocyte ratio (NLR), monocyte/lymphocyte ratio (MLR), platelet/lymphocyte ratio (PLR), systemic immune-inflammation index (SII) (neutrophil x platelet/lymphocyte), systemic inflammatory response index (SIRI) (neutrophil x monocyte/lymphocyte), pan-immune inflammation value (PIV) (neutrophil x platelet x monocyte/lymphocyte), C-reactive protein (CRP), uric acid, glucose, triglycerides (TG), total cholesterol, HDL, LDL, non-HDL, and triglyceride-glucose (TyG) index (Ln (TG [mg/dL] × glucose [mg/dL]/2)).

Purpose: To investigate the rare side effects of Osimertinib in a case of toxic epidermal necrosis.
Case Presentation: We report on a case of a 44-year old woman with lung adenocarcinoma harboring an EGFR-sensitizing mutation who was treated with Osimertinib as the second-line treatment. Ten days after Osimertinib initiation, a diffuse erythematous rash rapidly spread over the patient's trunk along with vesicles and purpuric macules; furthermore, she developed erythema and exfoliation on the face and trunk and severe mucositis.
