Figure 2. Notice temporal edema with localized engorgement of blood vessels—fluorescein staining reveals irregular, elevated corneal surface. Difficult to discern in the photo, but the edema is stromal and into Descemet’s layer—deeper than in Salzmann’s nodular degeneration and often without epithelial defect, unlike infiltrates.
