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

Figure 2

Inferotemporal limbal ulcer of Patient 2. Panel (a): slit-lamp examination with white arrow drawn across primary area of thinning. Panel (b): anterior segment optical coherence tomography (AS-OCT) image at presentation demonstrating area of significant corneal thinning (measured at 330 microns) and irregularity adjacent to an area of relatively normal cornea. As in Figure 1, the ulcer edges and interface between abnormal and normal cornea demonstrate hyperreflectivity. Panel (c): AS-OCT six months after presentation with improvement of thinning to 450 microns after medical therapy.
