Field of Research
Although the optics of vertebrate eyes is surprisingly optimized to the visual needs, human eyes tend to grow out of focus in industrialized populations. While genes determine the probability for myopia, visual experience provides the trigger. Using optics, systems analysis, pharmacology, molecular biology, psychophysics and electrophysiology, we try to understand the biological mechanisms of "visual control of eye growth", both in animal models and humans and to suggest strategies for intervention of myopia.
Measurements of optical properties of vertebrate eyes (photorefraction), behavioral studies (contrast sensitivity by automated OKN measurements), molecular biology (various techniques, including microarray), pharmacology, psychophysics, electrophysiology (microelectrode arrays, ERGs), chicken, mouse
