Visual Function Core

About our work

The NEI Visual Function Core provides expertise in using non-invasive techniques to measure visual function in animal models. Currently, the core provides training to use electrophysiological and imaging techniques and access to evaluate eye function.

Electroretinograms (ERG) used by the VFC affords a quantitative, objective, and noninvasive method to examine light-evoked neuronal activity and is commonly used to study the functional integrity of normal and diseased retinas. A state-of-art Optical Coherence Tomography (OCT) machine is also available to generate high quality optical section of retina in live animals.

In the near future, behavioral tests of visual function and other techniques for evaluating animal visual performance will become available. Please contact core head for detail applications and service.

NIH researchers develop first stem cell model of albinism to study related eye conditions

Researchers at the National Eye Institute (NEI) have developed the first patient-derived stem cell model for studying eye conditions related to oculocutaneous albinism (OCA).
