PURPOSE: To report a case of a corneal melanoma after trauma. METHODS: Case report. RESULTS: A 68-year-old man sustained an ocular injury from a blast furnace explosion in 1958. In 1998, he underwent a penetrating keratoplasty for a corneal scar. Histologic examination and cell markers of the host button revealed intrastromal and subepithelial melanoma. No clinical or microscopic evidence of adjacent conjunctival or uveal melanoma was found. CONCLUSION: Melanoma of the cornea can present as a stromal opacity after trauma.

In this article we review three different systems for evaluating the human optical system: placido-disc based corneal topography, scanning slit topography, and wavefront sensors. We briefly describe the principles of each system, and discuss the strengths and weakness. We suspect all three will be used by ophthalmologists in the coming decade.
