[Corneal ring opacity (Ascher ring)--a case report].
PATIENT: A 63-year-old man without complaints presented with a bilateral symmetric opacity of the cornea between the mid and the outer periphery which was classified as Ascher's ring. CONCLUSIONS: Ascher's ring is a very rare entity. Characteristic slit lamp features allow its differentiation from other anular corneal opacities. Corneal or systemic alterations of the lipid metabolism can be discussed. Heredity can be suspected but could not be proved as yet. The visual prognosis is excellent. Therapy is not necessary.
