ME/CFS Science @mecfsscience.org · 01/02/20262) The researchers found several abnormalities in their Long Covid cohort, even after accounting for cardiovascular risk factors, and the changes were most pronounced in the subgroup of patients meeting ME/CFS criteria. 1140
ME/CFS Science @mecfsscience.org · 01/02/20263) One of the abnormalities found by studying the retina is called venular flicker-induced dilation (fVID). It's how much the diameter of small veins (venules) changes in response to flickering light stimulation. In Long Covid patients fVID was reduced. 191
ME/CFS Science @mecfsscience.org · 01/02/20264) Another measure is called the central retinal arteriolar equivalent (CRAE). It refers to the thickness of the arterioles, the tiny arteries that bring oxygen-rich blood into the eye. This was also reduced in patients, especially those with ME/CFS. 1101
