On examination, unaided visual acuity was 20/20 in each eye. Slit-lamp examination revealed bilateral, symmetrical, circular, gray-white stromal opacities in the midperipheral cornea measuring 5 mm in diameter. The width of the ring was approximately 0.5 mm. Corneal sensation was normal, and there was no corneal vascularization or epithelial defects. The anterior chamber was deep and quiet, with no iris transillumination in either eye. Intraocular pressure by Goldmann applanation tonometry was 16 mm Hg in each eye. There was minimal nuclear sclerosis in each eye. Funduscopy was unremarkable apart from a small choroidal nevus in the right eye.
