The Role of Retinal Ganglion Cell Structure and Function in Glaucoma.

Glaucoma, a leading cause of irreversible blindness globally, primarily affects retinal ganglion cells (RGCs). This review dives into the anatomy of RGC subtypes, covering the different underlying theoretical mechanisms that lead to RGC susceptibility in glaucoma, including mechanical, vascular, excitotoxicity, and neurotrophic factor deficiency, as well as oxidative stress and inflammation. Furthermore, we examined numerous imaging methods and functional assessments to gain insight into RGC health.

Preliminary data on a novel smart glasses system for measuring the angle of deviation in strabismus.

Background/objectives: To propose a novel smart glasses device for recording eye movement and compare its results to the prism alternate cover test (PACT).

Subjects/methods: This method comparison study enrolled patients with strabismic conditions, who first underwent conventional strabismus evaluations (PACT in the primary position), followed by the smart glasses NeuroSpeed system (NSS) recording protocols. The video recordings were analysed using specialized software, to calculate the horizontal deviation from the primary position.

Increased Risk of Acute Coronary Syndrome in Ankylosing Spondylitis Patients With Uveitis: A Population-Based Cohort Study.

Background: Uveitis, a sight-threatening ocular inflammatory state, is associated with autoimmune diseases and systemic inflammation. This prolonged systemic inflammation may cause plaque formation in coronary arteries, subsequently resulting in acute coronary syndrome (ACS).

Methods: This retrospective, population-based study (15-year period) used the Longitudinal Health Insurance Database based on the National Health Insurance Research Database in Taiwan.

Statin Use Is Associated With a Lower Risk of Blepharitis: A Population-Based Study.

Background: Blepharitis is a common eye disorder that may be overlooked by patients and clinical practitioners. The symptoms of blepharitis often manifest as irritation, a burning sensation, grittiness, and itchiness and may decrease visual acuity if not treated promptly. Meibomian gland dysfunction (MGD), a common cause of blepharitis, is believed to be associated with increased inflammatory marker levels that may disrupt the composition of lipids produced by the sebaceous glands in the eyelids and ultimately cause tear film instability.

Anterior capsular contraction syndrome with hyperopic shift.

Purpose: To present a case of anterior capsular contraction syndrome with hyperopic shift two weeks after an uncomplicated combined cataract surgery and pars plana vitrectomy.

Observations: A 55-year-old man, with no known risk factors, who developed anterior capsular contraction syndrome with hyperopic shift two weeks after an uncomplicated combined cataract surgery and pars plana vitrectomy. Hyperopic shift was caused by posterior displacement of the intraocular lens with anterior flexion of the haptics.

Laser photocoagulation for the treatment of bilateral late-onset retinopathy of prematurity-related retinal detachment in an adult male: A case report.

Rationale: Retinopathy of prematurity (ROP) is one of the major leading causes of childhood visual morbidity worldwide. Retinal break and traction develop in regressed ROP can further result in rhegmatogenous or tractional retinal detachment years or even decades later.

Patient Concerns: Here, we reported a case of bilateral ROP related late complication in a 36-year-old male with a chief complaint of increased floaters in his left eye.

A Pulmonary Pleomorphic Carcinoma Patient with Exudative Retinal Detachment Secondary to Choroid Metastasis as Initial Presentation-A Case Report.

Choroid metastasis is the initial presentation of pleomorphic carcinoma (PC) of the lung. PC is classified as poorly differentiated non-small cell lung carcinoma. It has a tendency to metastasize early and has a poor response to chemotherapy, which often results in poor prognosis.

The impact of glucosamine on age-related macular degeneration in patients: A nationwide, population-based cohort study.

Purpose: To analyze the association between glucosamine (GlcN) use and the risk of age-related macular degeneration (AMD) using claims data from the National Health Insurance Research Database (NHIRD).

Methods: A retrospective, population-based study was conducted with NHIRD data from a 14-year period (2000-2013). Chi-squared and Student's t-tests were used to evaluate differences between the study and comparison cohorts for categorical and continuous variables, respectively.

Unilateral Situs Inversus of the Optic Disc in a Patient With Retinal Arteriolar Tortuosity.

Familial retinal arteriolar tortuosity (fRAT) is a rare autosomal dominant disorder that is characterized by tortuosity of the second- and third-order arterioles around the posterior pole of retina. Most cases with fRAT lack associated systemic vascular abnormality. Situs inversus, a congenital anomaly, features emergence of retinal vessels from the optic nerve head in a nasal direction, usually occurs bilaterally.

Central retinal artery occlusion combined with posterior ciliary artery occlusion after preoperative embolization of the middle meningeal artery for intracranial meningioma: A case report.

Rationale: Preoperative embolization of brain tumors has been widely used to minimize hemorrhaging during surgery, but anastomosis between vessels is sometimes overlooked and complications can occur. Herein we describe a case of rare complications of central retinal artery occlusion (CRAO) and posterior ciliary artery occlusion after embolization of the middle meningeal artery.

Patient Concerns: A 48-year-old woman experienced acute, painless loss of vision in her left eye during embolization of the middle meningeal artery for meningioma.

Neuroprotective effects of exogenous erythropoietin in Wistar rats by downregulating apoptotic factors to attenuate N-methyl-D-aspartate-mediated retinal ganglion cells death.

The aim of this study was to investigate whether exogenous erythropoietin (EPO) administration attenuates N-methyl-D-aspartate (NMDA)-mediated excitotoxic retinal damage in Wistar rats. The survival rate of retinal ganglion cells (RGCs) were investigated by flat mount analysis and flow cytometry. A total of 125 male Wistar rats were randomly assigned to five groups: negative control, NMDA80 (i.
