Researchers at the Oklahoma Health Sciences Center have developed the first ever genetic model of a microscopic part of the eye, the absence of which causes blindness. The study, aimed at knowing the effects of diabetes, focuses on the functioning of receptors work and the role of proteins and insulin in it. The doctors hope to find an effective treatment of diabetic retinopathy through the model. Various drugs and therapies will be tested on the model to find ways for enhancing the life of receptor cells and prevent blindness.
