Abstract

A 75-year-old male with a right eye history of chronic dry eye syndrome, glaucoma status post tube shunt, and Fuchs dystrophy status post Descemet stripping endothelial keratoplasty followed by penetrating keratoplasty (PKP) presented with a 2.7 × 4.2 mm corneal ulcer, culture positive for Shewanella algae and Klebsiella oxytoca. A topical antibiotic regimen of gentamicin 14 mg/mL and vancomycin 50 mg/mL was administered according to culture sensitivities. There was concurrent use of loteprednol 0.5% (Lotemax Gel, Bausch and Lomb, Rochester, NY, USA) and later addition of erythromycin 0.5% ointment. The corneal ulcer improved with antibiotic therapy but was complicated by poor patient follow-up. Descemetocele formation prompted PKP in the right eye. The graft was successful and visual acuity improved from a low of light perception to maximum of 20/200 Snelle.n.
