We examined four young men with keratoconus and posterior polymorphous corneal dystrophy. All four patients showed central corneal steepening and irregularity, and large areas of irregular polymorphous opacification at the level of Descemet's membrane (in at least one cornea of each patient), which are consistent with posterior polymorphous dystrophy.
