Multifocal atypical herpetic keratitis secondary to topical corticosteroids

Abstract

Figure A. OS: Slit-lamp biomicroscopy photograph with Cobalt Blue Filter. Fluorescein staining reveals two separate dendritic ulcers (white arrows) compromising the mid-periphery, both superonasal (at 9 and 10:30 o’clock), and superior (at 12 and 2 o’clock). Additionally, an ulcerative lesion with stromal compromise of about 3x2 mm with thinning of more than 50% of the total corneal thickness (white oval). Figure B. OS: optical coherence tomography of the cornea. An area of thinning (respected stromal remnant of 171 μm) with epithelial cyst on the stromal ulceration area. Figure C. OS: Slit-lamp biomicroscopy photograph with Cobalt Blue Filter. Fluorescein stain shows minimal staining on areas of epithelial dendritic ulcers, as well as almost complete healing of the stromal ulceration. Figure D. OS: optical coherence tomography of the cornea. Complete epithelialization of the thinned area (now reached thickness of 276 μm) and almost complete resolution of the epithelial cyst.
