To examine the cause of infectious keratitis treated by therapeutic keratoplasty.
The study comprised of 36 eyes (35 patients), all diagnosed with infectious keratitis, and all had undergone initial therapeutic keratoplasty at Fukuoka University Hospital between April 2005 to December 2013. The eyes were evaluated with regard to the causative disease, corneal perforation at first visit, selected keratoplasty, type of donor cornea, and visual prognosis retrospectively.
The causative diseases included keratomycosis (14 eyes), herpetic keratitis (8), bacterial corneal ulcer (3), acanthamoeba kratitis (3), and unknown (7). Corneal perforation was observed in 19 eyes (52.8%) at the first visit. Lamellar keratoplasty was performed in 26 eyes (72.2%) and penetrating keratoplasty in 10 eyes. Preserved frozen corneal buttons (19), fresh corneal buttons (17): eyebank (10), and imported (7), were used as the doner cornea. Visual acuity of 10/100 or above was achieved in 19 eyes (52.8%).
Keratomycosis was the most common cause of infectious keratitis in this study. Therapeutic keratoplasty was effective for severe cases with corneal perforations.
