WebEven moderate rises in intraocular pressure (IOP) or surgical manipulations in the anterior chamber may trigger corneal oedema and decompensation. Reduction of the IOP often leads to clearing of the cornea [5]. However, in advanced stages of PEX-related kerato/endotheliopathy, the potential reversing endothelial decompensation may be limited.
