Aciclovir-resistant herpes simplex virus (HSV) keratitis is an under-recognized cause of eye disease. Systemic foscarnet offers a treatment option for these challenging cases, alongside a review of other therapies.
Area of Science:
- Ophthalmology
- Virology
- Infectious Diseases
Background:
- Herpes simplex virus (HSV) keratitis is a significant cause of vision loss.
- Antiviral resistance, particularly to aciclovir, may be more prevalent than currently recognized.
Purpose of the Study:
- To report on three cases of aciclovir-resistant HSV keratitis treated successfully with systemic foscarnet.
- To review current pharmacological strategies for managing drug-resistant HSV keratitis.
Main Methods:
- Case series describing clinical presentation and treatment outcomes.
- Literature review of antiviral therapies for HSV keratitis.
Main Results:
- Successful treatment of three patients with aciclovir-resistant HSV keratitis using systemic foscarnet.
- Identification of foscarnet as a viable alternative when standard therapies fail.
Conclusions:
- Aciclovir resistance in HSV keratitis requires consideration in treatment-refractory cases.
- Systemic foscarnet is an effective therapeutic option for managing aciclovir-resistant HSV keratitis.
