How long does herpes simplex keratitis last?
Most herpes simplex eye infections get better in 1 to 2 weeks, although they can last longer. Treatment is usually needed to reduce the risk of complications.

How effective is ganciclovir against HSV-1?
When ganciclovir solution and ointment were compared in mice infected with ocular HSV (Inoue et al 1989), solutions of 0.3% and 0.03% were shown to be as effective as the ointments with the same concentrations. Preclinical tolerance studies The tolerance of GCV gel when applied topically to the eye has also been evaluated in animals.
Why does ganciclovir penetrate the corneal epithelium?
Corneal penetration of ganciclovir was due to the small size of the ganciclovir molecule, its high lipophilicity, and its high cellular affinity resulting from its structural analogy with the endogenous nucleosides. This may explain the high diffusion of ganciclovir in the corneal epithelium (pKa 2.2 and 9.4 at pH 6.5–7.4).
