The good doctor discusses how the eye is a window to the heart with the help of the OCT.

Blog vol 6.40. The Gut and the Eyes. One of my biggest jobs is to keep abreast of new research and advances in eye health. Most recently, we have seen new stem cell research, gene therapies, as well as new drugs for dry and wet macular degeneration. In January of this year, there was an article in the journal, Cell Death and Disease, that looked at cell apoptosis, specifically with the photoreceptors of the eye. (Read the article here ). Apoptosis is the genetic programming of deliberate and constructive cell death, allowing for the maintenance of healthy structures and systems in the body. Some estimates have the body replacing 50 to 70 billion cells daily by this process. Necrosis, on the other hand, is unplanned cell death caused by injury, toxins, or other negative outside factors; this causes inflammation and disrupts the body’s balance of things. There are stressors that speed up cell turnover. The study looked at photoreceptors in the retina and were able to demonstrate cellular recovery, even in late stages of apoptosis, recovery not breakdown. When certain stressors were reduced, by working with the mitochondria, there was recovery of the photoreceptor cells. How? Mitophagy, the mitochondria’s own process of programmed breaking down and then repurposing the recycled components for new ones. This mitochondrial repair helps to reverse the sequence of apoptosis for the photoreceptors. Mitochondria, how cool. How is this helpful for our eyes? Conditions like retinitis pigmentosa or macular degeneration directly involve the photoreceptors and may be slowed or reversed by helping the mitochondria. So, let’s take care of those mitochondria. There is some evidence for nutritional support for the mitochondrial system. The nutrient, Urolithin A (UA), which is a compound made in our gut from fiber found in pomegranates, berries, and nuts is the only clinically proven substance known to trigger mitophagy, made in the gut no less. Vitamin B3 is critical for mitochondria function, however vitamin B3 based supplements are still to be clinically tested for their support of cell recovery. Nutrients Coenzyme Q10 and L-carnitine are known to help the mitochondria generate energy, and interestingly, infrared light therapy has also been shown to benefit mitochondrial function. Again, food for thought. The gut and its function needs a lot of research. How do probiotics and nutrient precursors affect eye tissues? It is so interesting that the gut can be a factor in eye health. Maybe adding Urolithin A as a supplement is wise, along with the antioxidants in Lutein and Zeaxanthin we use to combat photoreceptor degeneration. Will keep you posted on any new developments.
