The following are true about herpetic eye disease :
In treating epithelial keratitis, topical acyclovir is more superior than oral acyclovir.
Herpes simplex epithelial keratitis typically present with dendritic ulcer with terminal bulbs at the end of each branch.
Topical corticosteroids are contraindicated in active herpetic epithelial keratitis.
According to HEDS study, oral acyclovir prevents patients with epithelial keratitis from developing stromal keratitis and iritis.
The following are true about Herpetic Eye Disease Study ( HEDS) :
At 6 months, there was no clinically or statistically significant difference in visual outcome was seen between the group receiving topical steroid and the group receiving placebo for HSV stromal keratitis.
Oral acyclovir is beneficial in active patients with HSV stromal keratitis already receiving concomittant topical steroid and trifluridine.
Oral acyclovir is beneficial in patients with HSV iridocyclitis who are already receiving topical corticosteroids and trifluridine.
Long term oral acyclovir reduced the recurrence rate both epithelial and stromal keratitis.
Sex and ethinicity are important factors in determining recurrence rate.

Which statement best describes the use of topical trifluridines for the management of herpes simplex infection?
It may have direct toxic effects on the epithelium with prologed use
It is always preferable to epithelial debridement
It is augmented by concomitant corticosteroid use

What statement accurately describes the role of acyclovir in the treatment of herpes zoster keratitis?
The proper dose is 400mg orally 5 times daily for 10-14 days
