ABSTRACT: Objective: To analyze the epidemiology, clinical diagnosis and treatment of fungal keratitis (FK) in hospitalized patients at the First Affiliated Hospital of Yangtze University in recent years. Methods: A retrospective investigation was conducted on the data of 137 cases of FK in our hospital from January 2019 to December 2022. The epidemiological characteristics, identification results of fungal strains, clinical treatment, and prognosis of the patients were analyzed. Results: Among the 137 FK patients, 89 were males and 48 were females, and the ratio of male to female was 1.85:1, The age of onset was the largest number of patients in 50-59 years old and 60-69 years old. The disease occurred most in autumn, winter and summer farming season (from September to December, January, May, June). 72 cases (52.6%) had a clear history of corneal injury, and 43 cases (31.4%) had a history of plant injury. Other risk factors include eye surface diseases, ophthalmic surgery, and wearing corneal contact lenses. The top three pathogens were fusarium (38.7%), aspergillus (23.3%), and alternaria (17.5%). 101 eyes showed improvement or cure after treatment with medication, 9 eyes underwent corneal stromal injection, 11 eyes were covered with conjunctival flap covering or amniotic membrane transplantation, 12 eyes were covered with corneal transplantation, and enucleation of ocular contents was performed in 4 eyes; Visual acuity was improved or maintained in 123 patients (about 89.8%). Conclusions: The incidence of FK in our hospital was mostly middle-aged and elderly men, mostly caused by corneal injury in the process of agricultural labor. The pathogens were mainly fusarium and aspergillus. The preferred treatment was medication, with severe cases requiring combined surgical treatment. Most patients can maintain or improve their vision after treatment.
