[Chinese expert consensus on the diagnosis and treatment of herpes zoster keratitis (2025)].

Varicella zoster virus keratitis (VZK) is a common infectious disease of the cornea. It has the clinical characteristics of multiple ocular tissue involvement, diverse corneal manifestations, and significant damage to corneal endothelial cells, and is prone to be misdiagnosed or missed. At present, a uniform diagnosis and treatment protocol of VZK is lacking at home and abroad. It is necessary to form consensus and guidance for accurate diagnosis and standardized treatment. The Ocular Infection Group of Chinese Ophthalmologist Association has facilitated relevant domestic experts, including corneal experts and dermatologists, to reach this consensus on the diagnosis, treatment, and prevention of VZK, on the basis of the previous publications, latest research progress, and expert clinical recommendations.
