Title of project:
The impact of off-axis astigmatism on the refractive development
Synopsis:
Refractive error is an optical imperfection of the eye in which the image foci
from infinity objects fail to fall on the retina, resulting in blurred images
when accommodation is relaxed. The various forms of refractive error are
myopia, hyperopia, and astigmatism. In the Asian Chinese population, the
prevalence of myopia is rapidly increasing, affecting over 80% of the young
adult population. However, until now, the mechanism for refractive error
development is still not well understood. Recent studies have indicated that
not only the fovea, where the photoreceptor cells are densely packed, but the
peripheral retina also contributes to refractive error development and eye
growth. Because off-axis astigmatism, an inherent optical aberration of the
eye, dominates in the peripheral visual fields, we hypothesize a feedback loop
that uses off-axis astigmatism as a visual cue to control eye growth. This
study will employ an experimental approach using the chick model to investigate
the effect of off-axis astigmatism on refractive error development.
