Light exposure decreases IOP in rabbits during the night.
Elevated IOP observed in rabbits during the dark phase of the circadian cycle decreased rapidly and reversibly when rabbits were exposed to light during the dark phase. The decrease of IOP does not result from decreased aqueous flow and only part of the decrease requires intact ocular sympathetic innervation.
