Keratoendotheliitis fugax hereditaria (KEFH) is an autosomal dominant corneal disease that periodically and fleetingly affects the corneal endothelium, stroma, and vision, eventually resulting in central corneal stromal opacities in some patients. The disease is characterized by episodes of unilateral ocular pain, pericorneal injection, and photophobia. The acute symptoms vanish in 1 to 2 days, but vision remains blurry for several weeks. Onset occurs between ages 3 and 12 years, and may involve either eye. Episodes generally decrease in frequency and become more mild with age (summary by Turunen et al., 2018). [from
