Visual Electrophysiology Laboratory and Clinic

This laboratory, under the direction of  Dr. Pierre Lachapelle, PhD, is interested in the functional assessment of vision from the retina to the visual cortex in the normal and diseased human subjects (newborn to elderly) as well as in the development of animal models of human retinal disorders.

Investigative techniques include: Electroretinography (flash and multifocal), Visual Evoked Potential (VEP), Histology (light and electron), Immunohistochemistry, Mathematical analysis of biopotentials (FFT, Wavelet transform, etc.), Molecular Biology, etc.  Most recent findings: Retinal vasculature and function can predict imminence of coronary heart disease; first documented case of end stage Retinitis Pigmentosa (RP) that started with a normal retina more than 30 years ago.
