Which two diagnostics are primarily used in evaluating herpes dendrites?

The evaluation of herpes dendrites, particularly in the context of herpes simplex keratitis, is best accomplished using specific dyes that highlight corneal epithelial lesions. Rose Bengal is one of the primary stains used because it binds to damaged epithelial cells and can reveal the characteristic dendritic ulcers associated with viral infections like herpes simplex. The exposed nerve endings within these lesions are also highlighted, facilitating diagnosis.

Lissamine Green is another stain that is beneficial in visualizing corneal epithelial damage. It stains dead or degenerated cells and helps to identify areas of the cornea that are affected, as well as areas of staining that might indicate disease processes such as herpes infections.

Together, Rose Bengal and Lissamine Green effectively delineate the dendritic pattern and any associated epithelial damage, making them suitable for diagnosing and managing herpes dendrites. Other options either do not provide the same clarity for these specific lesions or are designed for different purposes in ocular surface evaluations.
