Microbial keratitis is a sight-threatening ocular emergency which affects several million people worldwide each year, resulting in loss of vision and negatively impacting people’s quality of life. In this issue, we provide diagnostic and treatment guidance for all eye health workers, including specific recommendations for those working in settings where diagnostic laboratory support is either limited or not available. We also offer resources in the form of posters which can be used to raise awareness amongst community pharmacists and the public.
