Abstract
The choroid appears to play a role in the regulation of eye growth and may respond to defocus cues. We developed a combined OCT and video optotype stimulus system wherein the optotype may be adjusted for defocus and incidence angle at the retina. We imaged an initial single subject with OCT before and after watching a 40-minute video under two test conditions: no defocus and +5D defocus. This system offers the potential to investigate choroidal changes over the entire macula and under multiple stimulus conditions.
