Abstract Details


to report a keratoconic eye that developed viral keratitis after collagen crosslinking and responding well to antiviral therapy.


hospital of specialities of Rabat Morocco


3 deep stromal infiltrates appeared in central cornea of right eye of a 18-year-old boy postoperatively after 2 days, who underwent uneventful corneal collagen crosslinking with riboflavin and ultraviolet-A for the treatment of keratoconus. The initial impression was infectious corneal ulcer and a fortified antibiotic regimen was administered. After 48 hours there was no improvement, so we have decided to start oral valacyclovir 1000mg tree time per day.


The ulcer decreased markedly, the cornea cleared, and the stromal infiltrates decreased.


Collagen crosslinking with riboflavin-UVA is a minimally invasive method, but traditionally requires epithelial removal, which could be a predisposing factor to microbial keratitis
