He had total corneal epithelial defect, stromal edema, shallow AC, perforation site at superior limbus. Bscan normal. He was treated with topical steroids, antibiotics, lubricants, oral vitaminC &antioxidants. At 6months he had superficial punctuate keratitis, clear stroma, optic disc pallor, best corrected vision 6/36.
