An eye for detail

One of the smallest organs that can be regarded as most important to human development as the brain is the eye. The retina shares similar features with the brain leading scientists to hypothesize that treatments to cure diseases in and around the eye may result in treatments of diseases of the brain. The author reasons that the optic nerve is really an extension of the brain, which means that if the nerve is damaged, signals cannot be sent between the two organs. This paper focuses on the study of optic nerve regeneration to counteract this effect and treat diseases like glaucoma.
