Gene Therapy for Optic Nerve Regeneration: Modulating PTEN/mTOR, KLFs, and Sox11
Under normal conditions, adult RGCs keep the mTOR pathway largely off, which limits their ability to grow new axons (). PTEN is a gene that inhibits...

Quercetin and Fisetin as Candidate Senolytics in Optic Nerve Aging
Senescent cells build up in key eye tissues. In the trabecular meshwork (TM), senescence stiffens the meshwork and increases resistance to fluid...
Citrus Bioflavonoids (Hesperidin, Diosmin) for Ocular Hemodynamics
Blood vessels relax when their lining cells (endothelium) make the gas nitric oxide (NO). Hesperidin itself is a sugar-linked molecule that is broken...
Molecular Hydrogen and Redox Signaling in Ocular Neuroprotection
Beyond pressure-related injury, Hâ‚‚ has shown benefit in other eye models. In diabetic-like rodents, oral Hâ‚‚ water improved abnormal retinal blood...
Anthocyanins and Bilberry Extracts: Retinal Resilience and Aging Microvasculature
Animal research confirms that bilberry anthocyanins protect retinal cells by enhancing antioxidant systems and damping inflammation. In a rabbit...
Taurine and Retinal Ganglion Cell Survival Across the Lifespan
Taurine plays key cellular roles beyond being a nutrient. In the retina it acts as an organic osmolyte, helping cells adjust their volume under...
Green Tea Catechins (EGCG) for Neurovascular Health in Glaucoma and Aging
Preclinical studies consistently show EGCG helps RGC survival after injury or elevated IOP. In a mouse glaucoma model (microbead-induced high IOP),...
Melatonin, Circadian Rhythms, and Nocturnal IOP Dynamics
Melatonin is not only made by the pineal gland but also produced in the eye itself. Photoreceptors in the retina generate melatonin at night, and the...
The Gut–Eye Axis: Probiotics, Metabolites, and Intraocular Pressure
SCFAs are fatty acids with fewer than six carbon atoms, mainly acetate, propionate, and butyrate, produced by gut bacteria digesting fiber. They...
Magnesium for Vascular Dysregulation in Glaucoma and Aging Circulation
Magnesium influences blood vessels and endothelial function in several ways:
Resveratrol and Sirtuin Pathways: From Trabecular Meshwork to Longevity
The TM tissue acts as the eye’s drainage filter and becomes less cellular and more dysfunctional in glaucoma. Chronic oxidative stress and...
Macular Carotenoids (Lutein, Zeaxanthin, Meso-zeaxanthin) Beyond the Macula
Macular carotenoids act as optical filters and antioxidants in the eye. By absorbing short-wavelength light and scavenging reactive oxygen species...
Saffron (Crocins) in Optic Neuroprotection: Translating Retinal Evidence to Glaucoma
Antioxidant neuroprotection. In vitro and animal studies consistently find that crocin and crocetin guard retinal cells against oxidative stress. For...
Safety, Interactions, and Regulatory Oversight of Glaucoma Supplements
Multiple supplements are promoted in glaucoma, often for their antioxidant or circulation effects. For example, Ginkgo biloba is thought to improve...
Spermidine and Autophagy: A Longevity Nutrient for the Aging Eye
By inducing autophagy, spermidine helps cells clear damaged components and maintain mitochondrial health. For example, chronic spermidine feeding in...
Curcumin and Curcuminoids: Anti-inflammatory Strategies for Glaucoma Neuroprotection
In the eye, microglia (resident immune cells) amplify inflammation when activated. Curcumin dampens microglial over-activation and cytokine release....
Vitamin D Status, Intraocular Pressure, and Neuroinflammation
Several large surveys have tested if vitamin D levels correlate with glaucoma. For example, a Korean health-screening study of over 120,000 adults...
N-Acetylcysteine and Glutathione: Fortifying Antioxidant Defenses in the Aging Eye
NAC is a lipid-soluble cysteine source that crosses cell membranes and is quickly converted to cysteine, the rate-limiting building block for...
