Antiviral Medications in Eye Care
Ocular Antiviral Medication Management
Antiviral medications play a critical role in the management of viral eye infections, such as herpes simplex keratitis and herpes zoster, which can pose significant threats to ocular health if left untreated. These medications are designed to target and inhibit the replication of viruses, thereby reducing the severity of symptoms and preventing the progression of the infection. For eye care professionals, understanding the mechanism of action, proper dosing, and potential side effects of antiviral agents is essential for effective treatment. Early diagnosis and prompt initiation of antiviral therapy are key to preserving vision and preventing complications associated with viral ocular diseases.
