Abstract Details

Purpose:

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

Setting:

hospital of specialities of Rabat Morocco

Methods:

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.

Results:

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

Conclusions:

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