Redondo B, et al. - In this study, 17 healthy low caffeine consumers took a capsule of caffeine or placebo in a counterbalanced fashion to accurately discover the structural variations in the cornea and anterior chamber related to caffeine ingestion. It was noticed that the rise in the intraocular pressure correlated with caffeine consumption could be caused by an anterior chamber angle decrease, which could provide immunity to the outflow of aqueous humor. Moreover, for individuals at great risk for glaucoma onset or progression, the up to date results could be of particular significance and could assist to understand the mechanisms underlying caffeine-induced ocular hypertension.
