Mystery corneal opacity ring

Abstract

Introduction We present a case of an incidental finding of unusual ring-like bilateral corneal opacities in otherwise clear corneas in a person with no other ophthalmological disease except cataract. Clinical findings, laser scanning in vivo confocal microscopy and corneal topography findings do not correspond to any described corneal degeneration, so the aim of this presentation is to consult with fellow ophthalmologists regarding the origin and significance of the described changes.

Case outline “Mystery corneal ring” is found incidentally as a bilateral, asymptomatic, almost perfectly round in shape, white and situated adjacent to limbus. The appropriate diagnostics performed did not give an answer as to the origin of these symmetrical opacites.

Conclusion We present previously undescribed symmetrical bilateral corneal opacities, in search of an answer as to whether any of our fellow ophthalmologists have had similar cases in their practice or know what type of disorder it is.
