Sumario:BACKGROUND: Fungal keratitis is known as an important cause of sight threatening infection worldwide. Variation of clinical characteristics and treatment have been observed among different geographic regions. Currently, clinical data of fungal keratitis in South East Asia remain scarce. METHODS: A retrospective single study was conducted at King Chulalongkorn Memorial Hospital in Thailand. Medical records of patient with diagnosis of fungal keratitis between January 2016 and December 2018 were reviewed. Cases were identified using ICD-10 code. Data on demographics, clinical presentations, investigations and outcomes were collected. Mycological diagnosis was made in patients who had clinical presentation compatible with fungal keratitis and positive fungal detection in clinical specimen. RESULTS: During study period, fungal keratitis was diagnosed in 59 pts including 31 by mycological and 28 by clinical diagnosis. KOH preparation of corneal scraping was positive in 19 of 53 pts (35.8%). Culture from cornea, aqueous and vitreous yielded positive result in 18 of 53 (33.9%), 2 of 14 (14.3%), respectively. ITS sequence analysis was positive in 7 of 15 (46.7%) from cornea, 1 of 6 (16.7%) from aqueous and 2 of 2 (100%) from vitreous. Culture and molecular detection from clinical specimens provided additional mycological diagnosis in 8 and 5 cases with negative KOH preparation. Fusarium was the most common pathogen (33%) followed by Paecilomyces (9.7%), Aspergillus (6.4%), Candida (6.4%). Ten patients (32.2%) had only positive KOH preparation. All patients received treatment with topical antifungal agent, while 38 pts (64%) required systemic, 24 pts (40.7%) received intrastromal, 22 pts (37.2%) received intracameral and 3 pts (5.1%) received intravitreal antifungal therapy. Operation was performed in 21 pts (35.6%) which 6 (28.5%) required evisceration. Twenty-three patients (39%) had visual improvement after complete treatment. CONCLUSION: Fungal keratitis is not an uncommon disease. Fusarium was the most common etiologic agent similar to study from other region. Unfavorable outcomes were observed in majority of cases. Appropriate fungal culture and molecular detection from clinical specimens can be considered as they may increase diagnostic yield in some patients. DISCLOSURES: All Authors: No reported disclosures
