Zoster keratitis
ICD-10 B02.33 is a billable code used to indicate a diagnosis of zoster keratitis.
Zoster keratitis is an ocular complication of herpes zoster (shingles), which is caused by the reactivation of the varicella-zoster virus (VZV). This condition typically occurs in individuals who have previously had chickenpox, as the virus remains dormant in the sensory ganglia and can reactivate later in life. Zoster keratitis manifests as inflammation of the cornea and can lead to significant ocular morbidity if not treated promptly. Symptoms may include eye pain, redness, tearing, photophobia, and blurred vision. The condition can be diagnosed through clinical examination, often revealing dendritic ulcers on the cornea, which are characteristic of herpes virus infections. Treatment usually involves antiviral medications, topical corticosteroids, and sometimes pain management. Complications can include corneal scarring, vision loss, and secondary bacterial infections. Vaccination against varicella and herpes zoster is recommended for older adults to reduce the risk of shingles and its complications, including zoster keratitis.
