Bilateral corneal ring-opacity observed in long-term contact lens wearer

Abstract

This case presentation describes the appearance of unexplained bilateral stromal ring-shaped opacities in a 73-year-old female. A world-wide literature search has revealed only seven other reported cases of similar stromal ring-opacities. At this time, the etiology and composition of the rings remains unclear. However, due to the location, symmetry, bilaterality and non-inflammatory nature of the rings, they may represent a rare form of corneal dystrophy.
