Clinical Features, Risk Factors, and Therapy of Epithelial Keratitis after Cataract Surgery

Figure 2

Comparison of patients suffering epithelial keratitis combined with diabetes or not. Fluorescence staining of the corneal epithelial damage in a diabetic patient (a) and a nondiabetic patient (d). Confocal microscopic images from patient (a) showing the stromal edema and absence of subbasal nerve fibers in the area of corneal epithelial lesions (b) before the treatment for keratitis and obviously slender subbasal nerve fibers after the corneal epithelial healing (c). Confocal microscopic images from patient (d) showing the absence of subbasal nerve fibers in the area of corneal epithelial lesions (e) before the treatment for keratitis and sparse subbasal nerve fibers after the healing of the corneal epithelium (f). All confocal microscopic images are in the scale of 400 × 400 μm.
