Project Title: Developing a New Visual Function Test for Early Glaucoma Detection
Glaucoma is a major eye disease that causes gradual vision loss and eventual irreversible blindness. It is the second leading cause of blindness worldwide. Unfortunately, current visual function assessment methods are insufficient for early detection of glaucoma. It has been shown that glaucoma affects retinal ganglion cells in the parvocellular (PC) and magnocellular (MC) pathways, therefore will lead to impairment in contrast processing functions in these two pathways. Deficits in contrast processing functions may be a sensitive early indicator of glaucoma. Therefore, in this study, we will use novel stimuli in psychophysical paradigms that allow effectively independent assessment of glaucomatous deficits in contrast processing functions in the PC and MC pathways. The goal is to find an approach for early detection of glaucoma to facilitate early intervention and ultimately to prevent substantial vision impairment and blindness.
