Visual functions depend on the integrity of complex structures, first and most important that of the retina. Light perception by photoreceptor cells in the retina, transformation of these signals to electric impulses and finally, their transmission to the brain are the key steps involved in vision. However, due to its complexity, the retina is particularly vulnerable to toxic by-products of cell-metabolism. These substances play a crucial role in the development of degenerative alterations, and their negative effects increase with age.
Most of the toxic substances are generated in the mitochondria. With aging, mitochondrial functions deteriorate, and subsequently energy production decreases. This mitochondrial dysfunction in the retina can result in a progressive deterioration of vision. Maintaining normal mitochondrial functions is vital for maintaining healthy vision.
Acetyl-L-carnitine, omega-3 and coenzyme Q10 all play a fundamental role in mitochondrial functions. Together they contribute to maintaining normal retinal cell-metabolism and to decreasing the production of toxic metabolic by-products.
Phototrop® is clinically proven to improve visual functions. A controlled pilot study in patients suffering from early AMD (age-related macular degeneration) showed an improvement and subsequent stabilization of visual functions in the group treated with the metabolic compounds in Phototrop® while a slow impairment was seen in the control group.
