Benefits of dark chocolate intake on retinal vessels functionality - Nature

A prospective, randomized, blind, crossover clinical trial involving healthy subjects evaluated the effects of dark and milk chocolate on retinal perfusion and vascular response using OCT-A and DVA. Subjects underwent ophthalmologic evaluations before and after chocolate consumption, with primary outcomes focusing on changes in retinal perfusion and vascular response to flicker stimulation post-dark chocolate intake. The study adhered to ethical standards and was approved by the San Raffaele Ethics Committee.
