Bilateral idiopathic corneal opacity: A report of Ascher ring and a review of the literature

Abstract

Purpose: To present a case of a rare entity of Ascher ring, a bilateral corneal stromal opacification. Observation: A 70-year-old male with no ocular history who presented for cataract evaluation was found to have idiopathic bilateral circular stromal corneal rings. Conclusions: After completion of extensive history, examination, imaging analyses, and laboratory studies for workup of corneal opacities, we arrived at a diagnosis of Ascher corneal ring, an extremely rare entity. Importance: A rare entity should be considered after excluding other etiologies.
