Summary of the mechanisms possibly contributing to the clinical symptoms associated with FECD. Evidence of mutations and oxidative stress support the induction of UPR in FECD, which could cause decreased CE cell density and pump function followed by corneal edema. The clinical indications could also occur as a result of compromised pump function caused by the decreased RNA level expression of ion transporters demonstrated in this study, whose mechanism is not known.
