let me share some facts about viral infection of eye. primary viral infection of the eye is usually followed by recurrent infection that may involve any or all layers of cornea. cornea has three layers: epithelium stroma and endothelium. it is when the stroma affected it causes stromal keratitis. this may be due to direct infection or your own body's immune response to viral antigens. most common viral keratitis is herpes simplex viral keratitis. stromal keratitis is usually recurrent. the treatment prescribed to you is according to the protocol. you need to ensure that you use them accordingly and apply topical medication five times daily. the response should be evident by two to four days. if not then you can change from acyclovir to ganciclovir ophthalmic gel 0. 15% five times daily or trifluridine 1% drops nine times daily. topical corticosteroid pred forte (prednisolone) is to bring down your immune response and is thus indicated in immune mediated non-necrotizing stromal keratitis. debridement can sometimes be tried according to the lesion. antiviral medications should not be taken for more than 10 to 14 days as they cause epithelial toxicity. patients with frequent recurrences of ocular hsv may be placed on a long-term regimen of oral antiviral medication at the prophylactic maintenance dose. valacyclovir has been shown to be as effective as acyclovir in reducing the recurrence of ocular hsv disease. have a word word with your treating physician if you are worried about recurrence. take care. for further information consult an internal medicine physician online --> <link>
