As a new investigator, she recently received a three-year Medical Research Council operating grant allowing her to undertake the development of newer, more sensitive tests to screen for the early stages of glaucoma. Casson obtained her doctorate at Stanford University and has recently relocated from a Faculty position at the University of California, Davis. She will continue to participate in collaborative studies with other university centres. She is currently developing new methods of assessing changes in peripheral vision which occur during the early stages of disease such as glaucoma. Various aspects of visual sensitivity are being researched in order to understand the risk factors and mechanisms of damage in certain conditions such as glaucoma, optic neuritis, multiple sclerosis and brain injury.
Collaborative studies are under way with corneal specialists.
