Numerical modeling of therapeutic lens drug delivery in the anterior human eye for the treatment of primary open-angle glaucoma.

Proc Inst Mech Eng H 2020 Jul 7:954411920934960. Epub 2020 Jul 7.

Department of Mechanical Engineering, Indian Institute of Technology Kanpur, Kanpur, India.

A numerical model of drug delivery from a therapeutic lens in the anterior portion of the human eye has been developed for a more effective treatment plan of primary open-angle glaucoma. The numerical model takes into account the drug diffusion through the therapeutic lens along with heat transfer and aqueous humor flow in different orientations of the human eye (supine (two-dimensional) as well as standing (three-dimensional)). Results illustrate that the drug diffuses through the therapeutic lens to the cornea and is convected into the anterior chamber of the eye due to the temperature gradient across the eye. Read More

Primary open angle glaucoma genetics: The common variants and their clinical associations (Review).

Mol Med Rep 2020 Aug 9;22(2):1103-1110. Epub 2020 Jun 9.

Department of Ophthalmology, University Hospital of Heraklion, 71110 Heraklion, Greece.

Glaucoma is a group of progressive optic neuropathies that have in common characteristic optic nerve head changes, loss of retinal ganglion cells and visual field defects. Among the large family of glaucomas, primary open‑angle glaucoma (POAG) is the most common type, a complex and heterogeneous disorder with environmental and genetic factors contributing to its pathogenesis. Approximately 5% of POAG is currently attributed to single‑gene or Mendelian forms of glaucoma. Read More

Low systemic vitamin D as a potential risk factor in primary open-angle glaucoma: a review of current evidence.

Br J Ophthalmol 2020 Jun 30. Epub 2020 Jun 30.

School of Optometry and Vision Science, University of New South Wales, Sydney, Australia.

Currently, intraocular pressure is the only modifiable risk factor for glaucoma; thus, identifying other modifiable determinants may have far-reaching outcomes. There has been increasing interest in vitamin D status and glaucoma pathogenesis as low vitamin D has been identified by some studies as an independent risk factor for glaucoma. Although the exact mechanism of vitamin D in glaucoma remains uncertain, there is sufficient evidence to continue research in this area. Read More

Altered coupling of cerebral blood flow and functional connectivity strength in visual and higher order cognitive cortices in primary open angle glaucoma.

J Cereb Blood Flow Metab 2020 Jun 24:271678X20935274. Epub 2020 Jun 24.

Department of Radiology, Beijing Tongren Hospital, Capital Medical University, Beijing, China.

Primary open-angle glaucoma (POAG) has been suggested to be a neurodegenerative disease associated with altered cerebral vascular hemodynamics and widespread disruption of neuronal activity within the visual, working memory, attention and executive networks. We hypothesized that disturbed neurovascular coupling in visual and higher order cognitive cortices exists in POAG patients and correlates with glaucoma stage and visual field defects. Through multimodal magnetic resonance imaging, we evaluated the cerebral blood flow (CBF)-functional connectivity strength (FCS) correlations of the whole gray matter and CBF/FCS ratio per voxel for all subjects.

Chronic elevation of intraocular pressure (IOP) is a major risk factor associated with primary open angle glaucoma (POAG), a common form of progressive optic neuropathy that can lead to debilitating loss of vision. Recent studies have identified the role of nitric oxide (NO) in the regulation of IOP, and as a result, several therapeutic ventures are currently targeting enhancement of NO signaling in the eye. Although a low level of NO is important for ocular physiology, excess exogenous NO can be detrimental. Read More

The trabecular meshwork: Structure, function and clinical implications. A review of the literature.

J Fr Ophtalmol 2020 Jun 16. Epub 2020 Jun 16.

Ophthalmology Department, Centre Hospitalier National d'Ophtalmologie des Quinze-Vingts, IHU FOReSIGHT, 28, rue de Charenton, 75012 Paris, France; Ophthalmology Department, hôpital Ambroise-Paré, IHU FOReSIGHT, AP-HP, 9, avenue Charles-De-Gaulle, 92100 Boulogne-Billancourt, France; Université de Versailles Saint-Quentin-en-Yvelines, 78000 Versailles, France; Inserm, CNRS, Institut de la Vision, Sorbonne University, 17, rue Moreau, 75012 Paris, France.

Glaucoma is a blinding optic neuropathy, the main risk factor for which is increased intraocular pressure (IOP). The trabecular meshwork, located within the iridocorneal angle, is the main pathway for drainage of aqueous humor (AH) out of the eye, and its dysfunction is responsible for the IOP elevation. The trabecular meshwork is a complex, fenestrated, three-dimensional structure composed of trabecular meshwork cells (TMC) interdigitated into a multilayered organization within the extracellular matrix (ECM).

Mapping developmental trajectories and subtype diversity of normal and glaucomatous human retinal ganglion cells by single-cell transcriptome analysis.

Stem Cells 2020 Jun 18. Epub 2020 Jun 18.

Department of Ophthalmology and Visual Sciences, University of Nebraska Medical Center, Omaha, Nebraska, USA.

Glaucoma is characterized by a progressive degeneration of retinal ganglion cells (RGCs), leading to irreversible vision loss. Currently, there is no effective treatment for RGC degeneration. We are using a disease in a dish stem cell model to examine the developmental susceptibility of RGCs to glaucomatous degeneration, which may inform on the formulation of therapeutic approaches.

Fibronectin extra domain A (FN-EDA) elevates intraocular pressure through Toll-like receptor 4 signaling.

Sci Rep 2020 Jun 17;10(1):9815. Epub 2020 Jun 17.

Department of Ophthalmology and Visual Sciences, McPherson Eye Research Institute, University of Wisconsin-Madison, Madison, WI, United States.

Elevated intraocular pressure (IOP) is a major risk factor for the development and progression of primary open angle glaucoma and is due to trabecular meshwork (TM) damage, which leads to impaired aqueous humor outflow. Here, we explore a novel molecular mechanism involved in glaucomatous TM damage. We investigated the role of an endogenous Toll-like receptor 4 (TLR4) ligand, fibronectin-EDA (FN-EDA), in TGFβ2-induced ocular hypertension in mice. Read More

The Genetic and Endoplasmic Reticulum-Mediated Molecular Mechanisms of Primary Open-Angle Glaucoma.

Int J Mol Sci 2020 Jun 11;21(11). Epub 2020 Jun 11.

Department of Clinical Chemistry and Biochemistry, Medical University of Lodz, 90-419 Lodz, Poland.

Glaucoma is a heterogenous, chronic, progressive group of eye diseases, which results in irreversible loss of vision. There are several types of glaucoma, whereas the primary open-angle glaucoma (POAG) constitutes the most common type of glaucoma, accounting for three-quarters of all glaucoma cases. The pathological mechanisms leading to POAG pathogenesis are multifactorial and still poorly understood, but it is commonly known that significantly elevated intraocular pressure (IOP) plays a crucial role in POAG pathogenesis.
