RP Vision and Exercise

It is widely held that following a healthy diet, exercising and reducing stress is beneficial to our health in general and also benefits our eyes, as regular and moderate physical exercise, activates micro-circulation and blood circulation, which brings more nutrients and oxygen to the optic cells. Aerobic and anaerobic exercise, which will benefit RP patients? Aerobic exercise has been found to be neuroprotective in animal models of retinal degeneration. It will lower intraocular pressure, which is pressure in your eyes, and that helps ... Read more

Make Your Vision Top Priority in 2022

There are a few things that the eyes need to function properly: Oxygen, Nutrients, Glucose and constant neurological stimulation through specific ocular neurotransmitters. Reduced blood flow to the retina will cause accumulation of toxic and waste products in the eye tissue, it can also cause insufficient blood and oxygen supply to the optic cells. Toxins can cause obstruction, contamination, inflammation, degeneration and ultimately result in vision loss. Dormant optic cells may be inactive, but are not dead or totally dysfunctional. Many neuro ... Read more

Is Vitamin A safe for RP?

Dietary supplementation with vitamin A is occasionally prescribed as a treatment for RP. However, there is one specific gene for which vitamin A is not recommended: ABCA4. This is because vitamin A accumulates toxic pigments in the retina and accelerates the progression of RP. It is not recommended that RP patients with the gene mutation ABCA4 take vitamin A. It is also recommended that people who take vitamin A supplements monitor liver function annually. Vitamin A is generally not recommended for ... Read more

High Fat Diet and RP

The retina is considered a window to the brain, and retinal degeneration is a complex process involving environmental stress, which can affect vulnerable neurons. High-fat diet induced metabolic alterations may influence retinal homeostasis and accelerate RP deterioration. The scientific study provides evidence that short-term high-fat feeding promotes glucose intolerance. It also triggers the expression of inflammatory and oxidative markers in the retina, because the high-fat diet increases the abundance of potentially pro-inflammatory bacteria. Thus, it speeds up photoreceptor degeneration by promoting oxidative stress ... Read more

How to differentiate autoimmune retinopathy and inherited RP

Recently we have received some patients’ inquiries, they are concerned they have been misdiagnosed and that unlike in the case of inherited sight loss, they want to know more about autoimmune retinopathy, AIR for short.

Dormant cones are important for RP

Most RP mutations arise in rod photoreceptor genes, leading to diminished peripheral and night vision. To understand why cones die in RP and to be able to stop dying and revitalize dormant cones would be an enormous step forward. A group of researchers from the University of Louisville has made a step forward into reactivating dormant cones in the animal model of RP. First of all: why cones die in RP? Because rods allow the release of glucose from the Retinal Pigmented ... Read more

Manage inflammation for long term vision preservation

Inflammation, oxidative stress and poor ocular circulation are the top three factors that accelerate progressive vision loss in RP. Inflammation and optic cells death are tightly interconnected. Studies propose that inflammation is a consequence of the photoreceptor degeneration triggered by genetic defects. During photoreceptor cell death, inflammatory cells are activated by releasing inflammatory substances that contribute to rod and cone cell death. This eventually accelerates vision loss. While there are still no effective treatments for most degenerative retinal disorders, except for RPE65 ... Read more

Antioxidants Prolong Cone Survival and Maintain Cone Function in RP

Retinitis Pigmentosa (RP) is a devastating eye disease and at present, there are no known treatment options that can alter the rate of vision loss and eventual blindness. In a series of studies in animal models, the effects of exposing cones in the periphery of the retina to a large excess of oxygen results in progressive oxidative damage to cone photoreceptors and cone cell death. Cone cell death gradually spreads from the periphery of the retina toward its center, narrowing the visual ... Read more
