Retinal vessel responses to flickering light provocation in a cohort of black and white teachers: the SABPA study

Background: Retinal microvascular function can be assessed using flicker light induced provocation (FLIP). Reduced vessel dilation responses to FLIP are noted in various disease conditions. Comparative studies between ethnic groups are scarce, while the importance of different phases of the vessel responses during and following FLIP are not well studied. We compared retinal vessel dilation, constriction and vessel diameter parameters following FLIP in a cohort of black (n=152) and white (n=178) teachers.
