Summary
The study aims to examine how the vascular layer of the eyeball (choroidal layer) responds when part of the visual field is exposed to specially generated visual stimulus. The study goal will be accomplished by producing specific blur visual stimulus at a particular visual field position and measure any consistent thickness change pattern in the choroidal layer. We propose to test the hypothesis that regional changes in the choroidal thickness may be induced differently after short-term exposure to specific visual stimuli.
