RESUMEN
The article presents a case of fungal keratitis after penetrating keratoplasty (PKP). A 35-years old patient had previously undergone surgical removal of an intraocular foreign body and developed chronic keratouveitis and epithelial-endothelial corneal dystrophy. PKP and early postoperative period were uneventful. The patient was frequently monitored with anterior segment photos. Two weeks later, fungal keratitis occurred on the edge of the donor flap. Direct microscopic evaluation revealed fungus spores and filaments, but growth of fungi in culture was negative. Instillation of steroids and antibiotics was discontinued, specific therapy included fluconazole and amphotericin B. Despite the ongoing treatment, keratitis has repeatedly recurred, and infiltrates were scraped. Topical and systemic voriconazole was administered instead of fluconazole in combination with regular scarification. After 3 weeks of treatment with voriconazole, stable corneal epithelialization was achieved and the cornea has restored its transparency. During 1.5 years of the follow-up, keratitis did not reccur; sutures were removed, corrected visual acuity increased to 1.0. Patients who had undergone PKP are at risk of developing fungal keratitis. Frequent monitoring of such patients contributes to early diagnosis of infectious complications. In the absence of officinal antifungal eye drops, specialist has to supply the patient with ex tempore antimycotic agents and change the treatment according to its effectiveness in each specific case.
