Kubo M, Hata J, Ninomiya T, Matsuda K, Yonemoto K, Nakano T, et al. The cause of optic disc edema is unclear but there is general agreement that the final common pathway leads to a compartment syndrome from axonal edema in a structurally crowded optic disc [39] resulting in apoptotically induced retinal ganglion cell death [33].

A Systematic Literature Review Puja Mehta, Sebastian E. Sattui, Kornelis S.M. It is more commonly seen following cardioembolic strokes and is more likely to occur with larger infarct volumes. Background: Exosomes derived from cardiac microvascular endothelial cells (CMECs) under hypoxia can mediate cardiac repair functions and alleviate pyroptosis and oxidative stress during ischemia-reperfusion (I/R) injury. They may account for up to 20% of acute strokes and have been reported to have the highest 1-month mortality. 34(4):1005-9. Marks MP, Olivot JM, Kemp S, Lansberg MG, Bammer R, Wechsler LR, et al.
