Using Anterior Segment Optical Coherence Tomography to Monitor Disease Progression in Peripheral Ulcerative Keratitis

Figure 1

Superotemporal limbal ulcer of Patient 1. Panel (a): slit-lamp examination (white arrow indicates primary area of thinning). Panel (b): AS-OCT image at presentation demonstrating area of significant ulceration and thinning measured at 380 microns. The interface of the abnormal and normal cornea appears to be the most hyperreflective, which may be a sign of higher density of cellular materials in this region. Panel (c): AS-OCT six months after presentation with flattening of the ulcer and subsequent improvement of thinning to 537 microns after medical therapy. The cystic region that remains to the right of the arrow may be an area of abnormal healing.
