Figure 1. Slit lamp photos of the left eye at presentation. (A, B) Fluorescein-stained cornea with cobalt blue filter showing severe superficial punctate keratitis (diffuse corneal staining), a small epithelial defect and a paracentral leakage. (C) Fluorescein-stained cornea without cobalt blue filter showing diffuse corneal scarring with peripheral neovascularization. (D, E) Anterior segment optical coherence tomography showing anterior stromal scarring (hyper-reflectivity, blue arrow), intrastromal fluid collection (lacuna) (hypo-reflectivity, asterisk), epithelial bullae (arrowheads), possible entry site at an area of internal Descemet’s membrane discontinuity (red arrow), and an exit through an area of epithelial surface disruption (white arrow).
