Inequities in access to visual field testing and their outcome consequences
When visual field testing is infrequent, vision loss can slip by unnoticed. Late-stage diagnosis is a common result in underserved populations. Since...

Low-Carb Diets and Nocturnal Blood Pressure Dips: Ocular Perfusion Risks and Benefits
Research has shown that excessive night-time hypotension is associated with glaucomatous damage. In fact, Hayreh and colleagues found that night-time...
Macronutrient Patterns and Intraocular Pressure: A Systematic Evaluation
This article reviews the latest evidence on macronutrient patterns and glaucoma. We will survey epidemiologic studies of diet patterns...
Personalized Nutrition in Glaucoma: Nutrigenomic Interactions with Macronutrient Metabolism
APOE (Apolipoprotein E) – This gene makes a protein that transports cholesterol and fats in the body, especially in the brain and retina (). There...
Medium-Chain Triglycerides vs Long-Chain Fats: Rapid Ketosis and Visual Function
MCTs have been studied for brain and eye health. In ageing and certain eye diseases, glucose uptake can drop and cells starve for fuel. For example,...
Protein Intake, Homocysteine, and Pseudoexfoliation Glaucoma Risk
Controlled diet studies in healthy volunteers show exactly this relationship: an 8-day high-protein diet (about 21% of energy from protein, versus...
mTOR/Autophagy Modulation by Amino Acids in RGC Degeneration
Cells constantly balance between building up structures and recycling damaged parts. mTOR is a Master growth sensor: when nutrients are abundant,...
NR vs NMN vs Nicotinamide for Glaucoma: Which NAD+ Booster Has the Strongest Evidence?
Current research has focused on three NAD precursors: nicotinamide (vitamin B₃), nicotinamide riboside (NR), and nicotinamide mononucleotide (NMN)....
How Useful Is OCT at Each Stage of Glaucoma?
Each OCT result comes with color-coded maps and numbers. Green usually means “within normal limits,” yellow means “borderline,” and red indicates...
New Glaucoma Treatments in 2026: What Patients Should Know About Longer-Lasting Eye Pressure Control
Below we explain how these new treatments work, who might benefit, and how they compare to traditional drops. We focus on the options most talked...
Endothelin-1 Peptide and Glaucoma: Targeting a Problem Pathway
Endothelin-1 (ET-1) is made by cells lining blood vessels throughout the body, and it helps regulate normal blood pressure and flow. In the eye, ET-1...
Substance P, Pain, and Neuroinflammation in Glaucoma
Substance P (SP) is a signaling molecule made by nerve cells. When nerves are irritated or injured, they release Substance P into the surrounding...
GLP-1 Peptides and Glaucoma Risk: What We Know and What to Watch
A nationwide Danish registry study also found that GLP-1 agonist use was linked to a lower glaucoma risk. Compared to diabetic patients on other...
Nerve Growth Factor–Based Peptides and Optic Nerve Protection
In a rabbit glaucoma model (pressure raised by a gel in the eye), researchers injected NGF around the eye (retrobulbar) before damage. Those rabbits...
Heat shock protein-derived peptides and autoimmunity in glaucoma
Evidence suggests that T cells (a type of white blood cell) reacting against HSPs can harm the optic nerve. For example, patient studies have found...
Endothelin pathway peptides and optic nerve head ischemia in glaucoma
ET-1 is produced by many eye tissues (retina, ciliary body, trabecular meshwork, etc.). It normally helps regulate blood flow and aqueous humor...
MOTS-c and Glaucoma: A Mitochondrial Signal With Bigger Implications Than Eye Pressure?
In 2015, researchers discovered MOTS-c – a 16-amino-acid peptide encoded in mitochondrial DNA (mtDNA) (). It is produced from a short open reading...
Senolytics and the Glaucoma Niche: Clearing Old Cells for Longer-Life Signals
Indeed, multiple studies have found senescence markers in RGCs and optic nerve tissue in glaucoma models. Notably, removing those old RGCs has been...
