A 40-year-old patient presented complaining of red eye and decreased visual acuity that had persisted for about a month. His medical history included recent trauma to the right eye with a tree branch, which was treated with topical antibiotics and steroids. On examination, visual acuity was 1/40 in the right eye and 20/20 in the left eye. A white-gray corneal lesion was found in the right eye, with margins that were not quite defined, corneal satellite infiltrate, and intense conjunctival reaction. Results of intraocular pressure measurement were normal.
