Unique neovascularization pattern under ProKera (Bio-Tissue, Inc, Miami, Florida). Case 4 with moderate diffuse conjunctival inflammation, superior limbal ischemia, total corneal epithelial defect, and mild stromal haziness (A) showed progressive superficial neovascularization in the area where epithelialization took place at days 5 (B), 10 (C), and 14 (D). Such vascularization regressed following complete epithelialization of the cornea (E), resulting in a faint corneal haze and stationary pannus in the peripheral cornea 29 months later (F).
