Acute Hydrops in the Donor Cornea Graft in Non-Keratoconus Patients

A 44-year-old Hispanic male and 91-year-old Caucasian male presented to the clinic with acute vision loss and pain years after penetrating keratoplasty (PKP). Neither patient had a history of keratoconus. Both patients had a history of eye rubbing and intraocular device present in the anterior chamber. The first patient had a history of a glaucoma drainage tube and the second patient had an anterior chamber intraocular lens implanted. Anterior segment ocular coherence tomography showed deep stromal cystic cavities. Both patients exhibited breaks in the endothelium by ultrasound biomicroscopy and the histopathologic examination after repeat PKP. Those findings were most consistent with acute corneal hydrops in the donor graft.
