Before 1968, vision research at NIH was funded and overseen by the National Institute of Neurological Disease and Blindness [2] (now known as the National Institute of Neurological Disorders and Stroke), which was established in 1950, after President Harry S. Truman signed the Omnibus Medical Research Act. [2]
Distribution of rods and cones along a line passing through the fovea and the blind spot of a human eye [1]. A blind spot, scotoma, is an obscuration of the visual field.A particular blind spot known as the physiological blind spot, "blind point", or punctum caecum in medical literature, is the place in the visual field that corresponds to the lack of light-detecting photoreceptor cells on the ...
This is a location with no photoreceptor cells, where the retinal ganglion cell axons that compose the optic nerve exit the retina. This location is called the optic disc. There is no direct conscious awareness of visual scotomas. They are simply regions of reduced information within the visual field.
Neuro-ophthalmologists are often faculty at large university-based medical centers. Patients often have co-existing diseases in other fields (rheumatology, endocrinology, oncology, cardiology, etc.), thus the neuro-ophthalmologist is often a liaison between the ophthalmology department and other departments in the medical center.

The fibers from the retina run along the optic nerve to nine primary visual nuclei in the brain, from which a major relay inputs into the primary visual cortex. A fundus photograph showing the back of the retina. The white circle is the beginning of the optic nerve. The optic nerve is composed of retinal ganglion cell axons and glia.
The optic nerve is a cable connection that transmits images from the retina to the brain. It consists of over one million retinal ganglion cell axons. The optic nerve head, or optic disc is the anterior end of the nerve that is in the eye and hence is visible with an ophthalmoscope. It is located nasally and slightly inferior to the macula of ...

Bionic Vision Technologies (BVT) is a company, that has taken over the research and commercialisation rights of Bionic Vision Australia (BVA). BVA was a consortium of some of Australia's leading universities and research institutes, and funded by the Australian Research Council from 2010, it ceased operations on 31 December 2016.
