title: [Topical voriconazole as an effective treatment for fungal keratitis].
abstract: OBJECTIVE
  To evaluate the efficacy of topical voriconazole in patients with fungal keratitis caused by different fungal species.
  
  
  METHODS
  Interventional case series. Eighty-four patients aged 18 years or older from central China with confirmed fungal keratitis who presented at the outpatient department of Henan Eye Institute were enrolled in the study. The patients underwent in vivo confocal scanning laser microscopy examination, coneal scraping and microscopic examination and fungal culture, and then received topical voriconazole, closed curative effects were conducted. The sensitivity of three different diagnostic techniques, spectrum of the fungi, cure rate for fungal corneal infection related to each species were analyzed.
  
  
  RESULTS
  In our study, 84 patients were diagnosed with fungal keratitis based on clinical symptoms, and results of at least one of the examinations of in vivo confocal scanning laser microscopy, conventional smear, and corneal scraping culture and the sensitivity were 92.85%(78/84), 85.71%(72/84), 84.52%(71/84)respectively. In viro confocal scanning laser microscopy. Successful management was achieved in 83.33% of the patients. Topical voriconazole treatment failed in 14 patients(16.67%), who required surgical treatment. In 36 patients with Fusarium corneal infections, 26(72.22%)were successfully treated with topical voriconazole; however, in 18 patients with Aspergillus corneal infections and 7 patients with Alternaria corneal infections, 94.44% and 100.00% of them were successfully treated, respectively. In a case-based dynamic tracking study, in vivo confocal microscopy provided real-time dynamic detection of surviving hyphae. The existence of hyphae was(38.35±17.32)days for Fusarium,(25.00±16.11)days for Aspergillus,(21.00±4.36)days for Alternaria, and(41.50±31.68)days for the focus in the deep stroma. The duration of treatment was similar for all four groups.
  
  
  CONCLUSIONS
  Topical application of voriconazole is on effective method for the freatment of fungal keratitis Topical voriconazole is highly effective for fungal keratitis caused by Alternaria spp. and Aspergillus, however, for Fusarium, it is relatively low effective. (Chin J Ophthalmol, 2016, 52: 657-662).
