Infectious keratitis and sclerokeratitis caused by filamentous fungi prevail in agricultural regions with tropical and subtropical climates and are related mostly to mild abrasive corneal trauma especially after vegetable matter related injury. Biotechnological advances have introduced biological control agents in agriculture such as fungal-based biocontrol agents that use Beauveria and Metarhizium species as bioinsecticides. Keratitis and sclerokeratitis are the most frequent pathologies associated to Beauveria and Metarhizium infection that are the main entomopathogenic fungi used in biological control, although other clinical cases such as sinus, skin lesions, and disseminated infections have been reported. Search of publications was carried out using the databases: Scopus, Pubmed, ScienceDirect, MedLine Scielo. A total of 30 articles were retrieved from 1984 - 2021. From these, 17 keratitis and one sclerokeratitis clinical cases were related to Beauveria infection, while Metarhizium was linked to 13 keratitis cases and two sclerokeratitis clinical cases. Female sex predominated in both Metarhizium and Beauveria clinical cases, there was no significant difference in sclerokeratitis / keratitis by sex. Contact lenses use was a factor reported in 66.6% cases of infection with Metarhizium and 22.2% with Beauveria. The review of clinical cases of keratitis and sclerokeratitis related to Beauveria and Metarhizium suggests the need to consider entomopathogenic fungi in ocular pathologies and the risk that imply the misuse of contact lenses and agricultural/gardening activities.
