Equine fungal keratitis represents a substantial portion of keratitis cases in horses, with fungal involvement identified in approximately half of all infectious keratitis cases. Despite its prevalence, more comprehensive retrospective analyses are needed to better understand this condition. Outcomes vary, with approximately two-thirds of cases achieving complete healing with retained vision, although enucleation is often necessary. Predominant pathogens include Aspergillus and Fusarium, with yeast reported in a minority of cases. Resistance to common antifungal agents among filamentous fungi poses a significant challenge. Advances in diagnostics, including repeat culture and antifungal susceptibility testing, as well as the incorporation of PCR technology, hold promise for improving detection and guiding treatment decisions. Newer antifungals, combination therapies, and innovative modalities such as photodynamic therapy offer hope for improved outcomes. Continued research efforts are essential to further elucidate the epidemiology, pathogenesis, and optimal management strategies for this condition.
