Figure 2. Ocular mucositis revealed by slitlamp and in vivo confocal microscopy. Slitlamp microscopy (left panels) revealed corneal epithelial abnormalities characterized by two patterns of turbulence (sheet-like or superficial punctate keratopathy-like (SPK-like) lesions) that were highlighted by fluorescein staining. Confocal microscopy (right panels) revealed nonuniformity in size and intensity of superficial epithelial cells (A), cellular defects in the superficial cell layer (B), atypical arrangement of the multilayered structure of the epithelium (C), and poorly defined Palisades of Vogt (POV; D).
