[Isolated corneal intraepithelial dysplasia]

We present the case of an 83-year-old patient with an isolated epithelial dysplasia of the cornea. After corneal abrasion the lesion reoccurred 14 days later. The abrasion was then increased to cover the whole corneal epithelium and adjacent limbal and conjunctival areas were also biopsied. Histology revealed a corneal epithelial dysplasia stage 3, whereas the limbal and conjunctival biopsies showed normal epithelium. After resection two cycles of local mitomycin C application (2 cycles of 14 days each) were administered and 9 months after the second intervention the cornea remained clear with good vision. The investigation for human papillomavirus showed a type 6, which is not associated with an increased risk of malignancy.
