Hurricane Keratitis in Penetrating Keratoplasty

A characteristic “hurricane”-shaped epithelial keratitis was seen in 15 cases of recent penetrating keratoplasty. The keratitis appeared to be caused by the use of Maxitrol. The pattern of the keratitis was believed to be a manifestation of the normal healing pattern of the corneal epithelium. The fact that the toxicity reported here appeared only in grafted corneas indicates that the epithelium of the corneal graft is highly sensitive to topical medications. Therefore, this pattern might be expected to be seen with the use of other epithelial toxic drugs.
