Treatment for HSV on Cheek Below Eye with Watery Eyes
Treat this patient with oral acyclovir 400 mg five times daily for 7-10 days, combined with topical antiviral therapy such as ganciclovir gel 0.15% or trifluridine 1% solution applied to the periocular area. 1
Rationale for Combined Oral and Topical Therapy
The American Academy of Ophthalmology specifically emphasizes that oral antiviral therapy alone may not be sufficient to prevent progression of HSV blepharoconjunctivitis, and recommends adding topical antiviral treatment. 1 This is critical in your case because:
- The watery eye suggests possible conjunctival involvement or early ocular surface disease, even without frank eye involvement 1
- Periocular HSV carries significant risk of progression to ocular complications if undertreated 1
- The proximity to the eye (cheek below eye) places this in the high-risk periorbital zone 1, 2
Specific Treatment Regimen
Oral Antiviral Options (choose one):
- Acyclovir 400 mg five times daily 1
- Valacyclovir 500 mg two to three times daily 1
- Famciclovir 250 mg twice daily 1
Topical Antiviral (add to oral therapy):
- Ganciclovir gel 0.15% applied three to five times daily 1
- Alternative: Trifluridine solution 1% five to eight times daily 1

Critical Monitoring and Follow-Up
Schedule follow-up within 1 week to assess for: 1, 2
- Visual acuity changes
- Slit-lamp examination for corneal involvement
- Progression of conjunctival symptoms
- Development of keratitis, iritis, or other ocular complications 2
The watery eye warrants particular attention as it may represent early conjunctivitis or reflex tearing from periocular inflammation, both of which require close ophthalmologic surveillance. 1
Important Caveats
Avoid topical corticosteroids at this stage, as they can potentiate viral replication in active epithelial disease. 2 Corticosteroids should only be considered later under ophthalmologist supervision if inflammatory complications develop without active epithelial disease. 2
Add topical antibiotics to prevent secondary bacterial infection of vesicles, particularly given the periocular location where bacterial superinfection can lead to severe complications including cicatricial ectropion. 2
Special Populations
If the patient is immunocompromised, more aggressive therapy is required with potentially higher doses and longer duration. 3, 1, 2 Consider intravenous acyclovir 5-10 mg/kg every 8 hours if severe disease or systemic involvement develops. 3
Why Topical Therapy Alone Is Inadequate
While older guidelines suggested topical acyclovir for mucocutaneous HSV, topical therapy is substantially less effective than oral medication and its use as monotherapy is discouraged. 3 The combination approach addresses both the cutaneous lesion and prevents ocular progression, which is the primary concern in periocular HSV. 1
