Marginal ulcers (small white ulcers that appear on the cornea at the limbus) may indicate an allergic reaction to staphylococcal antigen.

This is a toxin-related complication of staphylococcal species that frequently cause blepharitis.

Pain, photophobia, and a foreign-body sensation are common. The ulcers are sterile and respond to topical steroids.
