This study aims to bridge that gap by investigating how acute sugar intake influences choroidal thickness.
This investigation will be a prospective, repeated-measures study. All subjects will arrive fasted and will be asked not to consume any outside food or beverages during the three-hour study period, and will be asked to abstain from caffeine intake for 12 hours before participation. A baseline OCT scan of the macula of the right eye will be performed using the Heidelberg Spectralis OCT system. Participants will then consume 30 grams of sugar in the form of glucose tablets. Macular OCT scans of the right eye will be repeated every 30 minutes for 3 hours following sugar consumption.
Exclusion Criteria:
Subjects receive 30g of oral glucose
Dietary Supplement: Oral glucose
Participants will consume 30 grams of sugar in the form of glucose tablets.
Change in choroidal thickness
The primary outcome for this investigation will be changes in choroidal thickness from baseline across timepoints.
Time frame: within 3 hours of baseline
