Compression keratopathy

A 31-year-old man developed a localized corneal epithelial lesion after exposure to a high-pressure fire extinguisher jet. Visual acuity was temporarily decreased from 20/20 to 20/40 and intraocular pressure was increased to 28 mm Hg. Both values returned to normal within 18 hours after treatment. This represents an extreme form of anterior corneal mosaic associated with microsplits of the corneal epithelium.
