Abstract
Introduction: Fungal keratitis is an ocular emergency that requires early and appropriate management. It can lead to significant visual loss. Standard treatment includes topical and systemic antifungals. In refractory cases, adjuvant therapies have been explored. The argon laser has shown higher cure rates than other traditional therapies.
Case presentation: We describe the case of a 55-year-old farmer with a 20-day history of foreign body sensation. The condition was classified as a fungal corneal ulcer caused by Alternaria spp. Argon laser treatment was performed with a 500-um spot for 0.2 s at 900 mW power. This led to a reduction in the corneal epithelial defect and complete healing.
Conclusion: Argon laser treatment for this refractory fungal ulcer resulted in complete healing of the epithelial defect, with minimal corneal opacity.
期刊介绍：
This peer-reviewed online-only journal publishes original case reports covering the entire spectrum of ophthalmology, including prevention, diagnosis, treatment, toxicities of therapy, supportive care, quality-of-life, and survivorship issues. The submission of negative results is strongly encouraged. The journal will also accept case reports dealing with the use of novel technologies, both in the arena of diagnosis and treatment. Supplementary material is welcomed. The intent of the journal is to provide clinicians and researchers with a tool to disseminate their personal experiences to a wider public as well as to review interesting cases encountered by colleagues all over the world. Universally used terms can be searched across the entire growing collection of case reports, further facilitating the retrieval of specific information. Following the open access principle, the entire contents can be retrieved at no charge, guaranteeing easy access to this valuable source of anecdotal information at all times.
