Herpes simplex infection is a common viral disease that affects the eyes and can lead to severe vision loss if left untreated. An effective ophthalmic delivery system for antiviral drugs is crucial for the treatment of this condition. One promising approach for the delivery of antiviral drugs for herpes simplex infection is the use of ocuserts. Ocuserts are a type of drug delivery system that are placed in the lower conjunctival sac of the eye and slowly release the drug over an extended period of time. Ocuserts are designed to provide a sustained release of the drug in the eye, which can help to achieve therapeutic levels of the drug in the affected area and to reduce the frequency of dosing. This can be particularly beneficial for the treatment of chronic conditions such as herpes simplex infection.
