RESUMO
BACKGROUND: Herein, we present the case of a young female patient with keratoconus, who was subjected twice to repeat keratoplasty, and each time, she experienced a corneal graft failure. FINDINGS: Under the suspicion of herpetic eye disease, we administered topical and systemic anti-herpetic treatment after the second repeat keratoplasty. The postoperative course was uneventful, and the corneal graft is clear, until recently. Immunohistochemistry and DNA-polymerase chain reaction were negative for herpes simplex virus-1 (HSV-1) in the host cornea, but they detected HSV-1 in both transplanted corneal grafts, thereby supporting our clinical hypothesis that graft-to-host HSV-1 infection elicited this chain reaction of complications in our patient. CONCLUSION: This clinical report illustrates in a unique way the dramatic impact an unsuspected herpetic infection in the corneal graft in cases of keratoplasty may have and underscores the necessity of suspecting and adequately treating these distinct cases.
RESUMO
UNLABELLED: We report the successful management of a rare case of bilateral post-laser in situ keratomileusis (LASIK) Fusarium oxysporum keratitis and propose a therapeutic strategy. A 19-year-old white man with no systemic diseases was referred to our emergency service 3 days after microkeratome-assisted myopic bilateral LASIK correction. He complained of blurred-vision, photophobia, and ocular pain. Clinical findings (satellite lesions, hypopyon) suggested fungal keratitis. Flaps were immediately lifted and rinsed with povidone-iodine 10%, and intensive topical and systemic and combined antifungal and antibacterial treatment was introduced. Topical cortisone drops were administered after 3 days. Despite initial deterioration of the clinical picture, all symptoms resolved quickly. Polymerase chain reaction indicated F oxysporum. Relapse occurred in the left eye, which was successfully managed. The final uncorrected distance visual acuity was 20/20 in both eyes. Fusarium oxysporum post-LASIK keratitis may occur in the early phase. Prompt diagnosis, interface irrigation with povidone-iodine solution, and intensive long-term treatment contribute to a favorable outcome.
