Figure 2. Slit-lamp photographs showing clinical progression of patient No. 2. (A) On day 1, eccentric, well-defined edge anterior one-third of stromal infiltration with overlying epithelial defect. (B, C) On day 3, progression of anterior stromal infiltration and scalloped-shaped border of epithelial defect demonstrated by fluorescein staining. (D) On day 7, multifocal, large, deep and dense anterior stromal infiltration with corneal melting. (E) On day 12 (after 3 days of intravenous acyclovir), improvement of stromal infiltration, but still of stromal melting at center of the lesion. (F) On day 30 (after 1 week of autologous serum eye drops), improvement of corneal melting and decreasing size of epithelial defect.
