Abstract
Purpose
To analyze the Paecilomyces keratitis cases in Korea and compare cases from foreign literature.
Methods
The records of 3 patients diagnosed with Paecilomyces keratitis at our hospital and other reported cases in Korea were evaluated to examine the predisposing factors, clinical aspects, antifungal therapy, therapeutic surgery, and visual outcome and compared with previously reported foreign cases.
Results
In Korea, 1 patient was female, 4 patients were male and had predisposing factors including prior corneal trauma or surgery, except 1 spontaneous occurrence. All 5 eyes of 5 patients had poor initial visual acuity, less than finger count, and deep corneal infiltration. The patients were treated with multiple topical and systemic antifungal treatments such as intracameral or intrastromal voriconazole injections and required evisceration and penetrating keratoplasty. However, the final outcomes were unsatisfactory. Previously reported cases from foreign literature also had predisposing factors such as corneal surgery, trauma, and soft contact lens use. They were resistant to antifungal therapy and eventually led to surgeries such as penetrating keratoplasty and the final outcomes were poor.
Conclusions
Frequently, Paecilomyces keratitis has direct risk factors and is resistant to many topical and systemic antifungal agents. In the majority of cases, therapeutic surgery was required and the final visual outcomes were poor. When Paecilomyces keratitis is suspected, we suggest aggressive therapy including intracameral and intravitreal injections of voriconazole in the initial treatment.
