From the Guidelines
Treatment of periorbital HSV infection should prioritize oral antiviral medications, with acyclovir 200 to 400 mg five times a day, valacyclovir 500 mg two or three times a day, or famciclovir 250 mg twice a day being the standard first-line therapy. When considering treatment guidelines for HSV infection periorbital, it is essential to prioritize the most recent and highest quality study, which in this case is the conjunctivitis preferred practice pattern study published in 2024 in the journal Ophthalmology 1. According to this study, possible topical options include ganciclovir 0.15% gel used three to five times per day or trifluridine 1% solution five to eight times per day. However, topical antivirals alone may not be adequate in preventing the progression of HSV blepharoconjunctivitis, but the addition of topical antiviral treatment has been effective. Some key points to consider when treating periorbital HSV infection include:
- Oral antivirals are the primary treatment, with the goal of reducing symptoms and preventing complications
- Topical antivirals can be used as adjunctive therapy, but should be used with caution due to potential toxicity, such as epithelial toxicity caused by trifluridine if used for more than 2 weeks
- Topical corticosteroids should be avoided as they can potentiate HSV epithelial infections
- Patients should be monitored for potential ocular involvement and followed up within 1 week of treatment to assess the effectiveness of the treatment and potential need for adjustment. It is also crucial to note that neonates require prompt consultation with the pediatrician or primary care physician, because systemic HSV infection is a life-threatening condition 1. Overall, the treatment of periorbital HSV infection should be guided by the most recent and highest quality evidence, with a focus on reducing morbidity, mortality, and improving quality of life.
From the Research
Treatment Guidelines for HSV Infection Periorbital
- The treatment protocol for HSV infection periorbital is not explicitly mentioned in the provided studies, but general treatment guidelines for HSV infection can be applied 2, 3, 4, 5, 6.
- For immunocompetent patients, standard oral acyclovir (ACV) therapy should be initiated at a dose of 200 mg orally, five times a day for the first 3 to 5 days 2.
- If the response is poor, the dose of oral ACV should be increased to 800 mg five times a day 2.
- If no response is seen after 5 to 7 days, alternative regimens such as topical trifluridine (TFT) or intravenous foscarnet should be considered 2.
- For recurrent lesions, high-dose oral ACV (800 mg, five times daily) or intravenous foscarnet (40 mg/kg tid or 60 mg/kg bid) can be used as soon as possible 2.
Antiviral Medications
- Valacyclovir is a highly bioavailable prodrug of acyclovir and can be used for the treatment of herpes simplex, herpes zoster, and other viral infections 4.
- Famciclovir is a highly bioavailable prodrug of penciclovir and can be used for the treatment of herpes simplex and herpes zoster 4, 5.
- Single-day treatment with valacyclovir or famciclovir can be effective for orolabial and genital herpes 3.
