Drug contraindicated in dendritic keratitis is: March 2012
**Core Concept**
Dendritic keratitis is a viral infection of the cornea caused by the herpes simplex virus (HSV). The condition is characterized by the presence of branching, tree-like lesions on the cornea. Effective management of dendritic keratitis requires careful consideration of antiviral medications to prevent further disease progression.
**Why the Correct Answer is Right**
The correct answer is prednisolone, a corticosteroid. However, prednisolone is contraindicated in dendritic keratitis because it can exacerbate the disease by promoting the replication of the herpes simplex virus. Corticosteroids can suppress the immune response, allowing the virus to spread and potentially leading to more severe corneal damage.
