Project Title

Cone contrast sensitivity on juvenile myopia progression

Synopsis

The human retina contains three classes of cone photoreceptor that are sensitive to light of long (L), middle (M) or short (S) wavelengths, respectively, under photopic condition. It has been suggested that a lower prevalence of myopia was found in people with high L:M cone ratios, even with normal colour vision. Also, a lower prevalence of myopia was found in students with red-green colour vision deficiency. 

My study is to investigate the relationship between myopia prevalence/progression and cone contrast sensitivity, which aims to (1) gain the knowledge about the contribution of three different classes of cones in juvenile myopia progression, (2) understand the reason for the lower prevalence of myopia in colour deficient children, and (3) provide information on the mechanism of cone interaction(s) in myopia development.
