Is Glaucoma an Energy Failure Disease? Mitochondria, Aging, and the Optic Nerve
Retinal ganglion cells are the nerve cells in the eye that send visual signals from the retina to the brain. They have an especially high energy...

Disease-modifying glaucoma drugs
Right now, no therapy has been proven to do this in patients. In large, decades-long studies only pressure lowering showed a clear benefit. In fact,...
NR vs NMN vs Nicotinamide for Glaucoma: Which NAD+ Booster Has the Strongest Evidence?
Current research has focused on three NAD precursors: nicotinamide (vitamin Bâ), nicotinamide riboside (NR), and nicotinamide mononucleotide (NMN)....
Ketogenic Signals and Beta-Hydroxybutyrate: IOP, Neuroprotection, and Longevity Intersections
The retina, especially RGCs, is a highly active tissue that needs a lot of energy to work. This energy comes from tiny structures in cells called...
The Glaucoma Energy Crisis: How Pyruvate Rescues Failing Eyes (And Why Your Fitness Level Matters)
Even if you load up on pyruvate, an inactive body wonât convert it to extra ATP unless itâs needed. Instead, the surplus pyruvate enters normal...
Oxidative Stress, Hormesis, and the Hyperoxia Paradox in Glaucoma
In theory, brief exposure to high oxygen (like short HBOT sessions) could activate protective pathways inside eye cells. One key pathway involves the...
Neuroprotection Beyond Pressure: Whatâs Real, Whatâs Hype
A recent review reminds us that after decades of work, âonly a handful of neuroprotective therapies have succeeded clinicallyâ (). In other words,...
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...
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...
Coenzyme Q10 as a Mitochondrial Adjunct in Glaucoma and Lifespan Health
Notably, in the topical CoQ10 trial (), all eyes were also on standard drugs (timolol/dorzolamide), and CoQ10-treated eyes fared better. Thus, CoQ10...
Nicotinamide and NAD+ Boosting for Glaucoma Neuroprotection and Healthy Aging
NAD<sup>+</sup> is a ubiquitous coenzyme that facilitates ATP production via glycolysis and oxidative phosphorylation, and serves as a substrate for...

Mitochondria
Mitochondria are tiny structures inside most of your cells that act like power plants, producing the chemical energy cells use to do work. They turn the breakdown products of food into ATP, the molecule that powers motion, thinking, and repair. Mitochondria also help regulate cell death, balance calcium levels, and send signals that influence how the whole cell behaves. Each mitochondrion has its own small set of genes, and they reproduce and change shape through processes called fusion and fission. When mitochondria become damaged or worn out, cells remove them through a cleanup process so the rest of the cell stays healthy. If mitochondria arenât working well, tissues that need a lot of energyâlike the brain, heart, and musclesâcan suffer, and mitochondrial problems are linked to aging and many diseases. Lifestyle factors such as diet, exercise, and sleep influence mitochondrial health, and researchers are exploring therapies that support their function. Understanding mitochondria matters because keeping them healthy helps maintain energy, resilience to stress, and overall tissue function as we age.
