What are potential ocular complications of Herpes Zoster Ophthalmicus?

Herpes Zoster Ophthalmicus (HZO) is a viral infection that results from the reactivation of the varicella-zoster virus in the trigeminal nerve. It can lead to various ocular complications due to its involvement with the tissues of the eye.

The correct answer highlights conjunctivitis, keratitis, and anterior uveitis as potential complications. Conjunctivitis can occur due to inflammation of the conjunctival tissue in response to the viral infection. Keratitis, or inflammation of the cornea, is also common and can lead to significant vision impairment if not treated appropriately. Anterior uveitis, which involves inflammation of the uvea at the front part of the eye, can cause symptoms such as pain, light sensitivity, and redness, potentially leading to further complications like glaucoma if left unmanaged.

This selection accurately encompasses the typical ocular complications associated with HZO, as medical literature often identifies these conditions as common sequelae of this viral infection. The presence of multiple types of inflammation—conjunctivitis, keratitis, and uveitis—illustrates the range of possible complications affecting different structures within the eye due to the reactivated virus. These complications warrant immediate evaluation and treatment to prevent long-term damage to the
