Which type of keratitis associated with HZO is characterized by punctate epithelial lesions?

Pseudodendrites are indeed characterized by punctate epithelial lesions, which is a distinctive feature associated with herpes zoster ophthalmicus (HZO). In this condition, the corneal epithelium exhibits a specific pattern of damage due to the viral infection, leading to the formation of these lesions. Pseudodendrites appear similar to true dendritic ulcers caused by herpes simplex but are distinct in their morphology and clinical presentation, often described as having a beaded appearance.

These punctate lesions arise due to the viral replication in the corneal epithelium, causing localized necrosis and disruption of the epithelial layer. While the other types of keratitis mentioned can also be related to ocular complications and may present with varying clinical signs, they do not specifically produce the punctate epithelial lesions that are characteristic of pseudodendrites. Understanding this differentiation is crucial for accurate diagnosis and appropriate management of corneal complications associated with herpes zoster.
