Introduction: Triggered by the COVID-19 pandemic, medical education has moved online, tasking medical educators with developing virtual learning experiences. This is particularly challenging for less-represented disciplines, such as ophthalmology. We designed a red eye clinical reasoning case for preclinical medical students, which can be delivered virtually, using video conference software.

Diabetic retinopathy (DR) is a common consequence in type 2 diabetes (T2D) and a leading cause of blindness in working-age adults. Yet, its genetic predisposition is largely unknown. Here, we examined the polygenic architecture underlying DR by deriving and assessing a genome-wide polygenic risk score (PRS) for DR.

Catalyzed by endothelial nitric oxide (NO) synthase (eNOS) activity, NO is a gaseous signaling molecule maintaining endothelial and cardiovascular homeostasis. Principally, NO regulates the contractility of vascular smooth muscle cells and permeability of endothelial cells in response to either biochemical or biomechanical cues. In the conventional outflow pathway of the eye, the smooth muscle-like trabecular meshwork (TM) cells and Schlemm's canal (SC) endothelium control aqueous humor outflow resistance, and therefore intraocular pressure (IOP).

Twelve tips for teaching ophthalmology in the undergraduate curriculum.

Med Teach

January 2021

Division of Pediatrics and Adolescent Medicine, Emory University School of Medicine, Atlanta, GA, USA.

Ophthalmology education in the undergraduate medical curriculum has declined, and graduating healthcare professionals express discomfort with basic evaluation and management of ophthalmic complaints. With the growing aging population, ophthalmic needs will continue to rise, underscoring the need for increased eye care. This article offers 12 tips for increasing undergraduate ophthalmic education, which can be implemented strategically within limited established curricular time, or in novel ways outside the traditional curriculum.

Aim: To test our hypothesis that activation of protein kinase A (PKA) signal pathway by β-adrenergic agonist plays an important role in the protecting of cultured retinal pigment epithelial (RPE) cells against the hydroxychloroquine (HCQ) toxicity.

Methods: Cultured human RPE cells were treated with 1) HCQ, 2) HCQ with salbutamol (a β2-adrenergic receptor agonist), and 3) HCQ with salbutamol and a PKA inhibitor, and compared these to 4) untreated cells (controls). After treated for 24h, cell vacuolation, cells viability, PKA and PKA kinase activity levels were determined by the measurement of the size of vacuoles using Image J software, the cell counting with a dye-exclusion testing, Western blot and PKA kinase detection, respectively.

Glaucoma is a neurodegenerative eye disease that results in retinal ganglion cell loss and ultimately loss of vision. Elevated intraocular pressure (IOP) is the most common known risk factor for retinal ganglion cell damage and visual field loss, and the only modifiable risk factor proven to reduce the development and progression of glaucoma. This has greatly influenced our approach and assessment in terms of diagnosis and treatment.

LOXL1 folding in exfoliation glaucoma.

Adv Protein Chem Struct Biol

April 2020

Eye and Vision Research Institute, Department of Ophthalmology, Icahn School of Medicine at Mount Sinai, New York, NY, United States.

Exfoliation syndrome (XFS) is an age-related disease defined by the deposition of aggregated fibrous material (XFM) in the peri-cellular space. Principal morbidity occurs in the eye, where XFM accumulates on the anterior ocular tissues. GWAS have found that certain genetic variants of lysyl oxidase-like 1 (LOXL1), a matrix cross-linking enzyme that is required for elastic fiber formation confer risk for the development of XFS, but are not a single causative factor as many genetically affected individuals do not develop XFS or subsequent glaucoma (XFG).

Importance: Although the central visual field (VF) in end-stage glaucoma may substantially vary among patients, structure-function studies and quality-of-life assessments are impeded by the lack of appropriate characterization of end-stage VF loss.

Objective: To provide a quantitative characterization and classification of central VF loss in end-stage glaucoma.

Design, Setting, And Participants: This retrospective cohort study collected data from 5 US glaucoma services from June 1, 1999, through October 1, 2014.

Exfoliation syndrome (XFS) is an age-related disease involving the deposition of aggregated fibrillar material (exfoliation material) at extracellular matrices in tissues that synthesize elastic fibers. Its main morbidity is in the eye, where exfoliation material accumulations form on the surface of the ciliary body, iris, and lens. Exfoliation glaucoma (XFG) occurs in a high proportion of persons with XFS and can be a rapidly progressing disease.

Purpose: To examine the choroidal neovascularization (CNV) fluorescein angiographic perfusion and visual acuity 1 week after photodynamic therapy (PDT) with verteporfin (Visudyne, Novartis AG, Switzerland) on predominantly classic, subfoveal lesions in age-related macular degeneration (AMD).

Method: A retrospective case series study was conducted on the 1-week outcome of PDT treatment of 76 of 79 consecutive patients with the subfoveal, predominantly classic CNV form of AMD. Leakage from CNV was assessed by fluorescein angiography and best-corrected visual acuity determined on projected Snellen charts using a standardized protocol.
