The chickenpox in the eye is caused by the varicella-zoster virus infection in the eye, which can lead to herpes zoster virus keratitis, and is treated in the following ways: 1. The corneal damage caused by varicella-zoster virus infection should be repaired as soon as possible to avoid combined bacterial infections that may leave a scar on the cornea and lead to permanent vision loss, for example, recombinant bovine basic fibroblast growth factor eye drops and calf serum deproteinized eye gel are commonly used. 3. For example, flumetron eye drops are commonly used at present.
