Deep research and expert guides on maintaining your visual health.
Introduction Vision loss from optic nerve injury or glaucoma happens because retinal ganglion cells (RGCs) fail to regrow their axons. In adult mammals, the intrinsic growth program of RGCs is normally shut off, so damaged nerves do not heal o...
Introduction Taurine is a nutrient-rich amino sulfonic acid found in high concentrations in the retina and other neural tissues. In fact, taurine levels in the retina are higher than in any other body tissue, and its depletion causes retinal ...
EGCG and Neurovascular Health in Glaucoma and Aging Green tea cultures have long prized their tea’s catechins—particularly epigallocatechin-3-gallate (EGCG)—for promoting health. Modern research suggests EGCG’s potent antioxidant, anti...
Resveratrol’s Promise in Glaucoma: Ocular Cells and Systemic Aging Resveratrol is a polyphenolic compound often touted as a “caloric restriction mimetic” and SIRT1 activator with antioxidant and anti-inflammatory effects. Early studies sh...
Spermidine: An Autophagy-Inducing Polyamine for Eye Health Spermidine is a naturally occurring polyamine found in all cells and in many aging-friendly foods. It has recently attracted attention as an autophagy inducer and “longevity” nutr...
Introduction Citicoline, also known as CDP-choline, is a naturally occurring compound that supports nerve cell function. It serves as a key precursor for phospholipids — essential components of cell membranes — and boosts levels of importa...
Alpha-Lipoic Acid in Glaucoma: A Neurovascular Antioxidant Strategy Glaucoma is a progressive optic neuropathy in which elevated intraocular pressure, vascular insufficiency, and oxidative stress contribute to retinal ganglion cell (RGC) d...
Introduction Retinal ganglion cells (RGCs) are the neurons that send visual signals from the eye to the brain. They rely on a high-energy metabolism because they must maintain electrical signals over long distances. In glaucoma and related opti...
