摘要: Zinc, a trace element that influences cell metabolism through variety of mechanisms, appears to play an integral role in maintaining normal ocular function. This is present high concentrations tissue, particularly retina and choroid. Zinc deficiency has been shown number species result gross, ultrastructural electrophysiologic manifestations. The physiological functions for zinc have studied predominantly retinal pigment epithelium where believed interact with taurine vitamin A, modify photoreceptor plasma membranes, regulate the light-rhodopsin reaction, modulate synaptic transmission serve as antioxidant. Suboptimal status North America may influence development progression several chronic eye diseases. supplementation trials epidemiological studies produced conflicting results concerning age-related macular degeneration. Additional well-controlled...
