Abstract
Vertical striae in the posterior cornea were produced experimentally in 10 human subjects by depriving the anterior corneal surface of its normal O2 supply and inducing corneal edema. These striae were similar in appearance and time of occurrence to those observed in gel lens wearers. Three subjects also wore gel lenses and developed vertical striae while wearing their lenses. These striae were eliminated by increasing the O2 concentration at the anterior lens surface. Vertical striae may be caused by corneal edema accompanying gel lens wear.
