Laminated posterior vitreous cortex associated with idiopathic macular hole.

Abstract

To report an unusual preretinal opacity associated with an idiopathic macular hole (MH) that was identified by optical coherence tomography. Observational case report. A 59-year-old woman with a preretinal linear opacity running across an MH was examined by optical coherence tomography. Optical coherence tomography showed a full-thickness MH with a superiorly hinged flap. The preretinal opacity was identified as a part of a laminated vitreous cortex that was perpendicularly attached to the apex of the flap. A horizontal scan showed a partly double-layered posterior vitreous cortex. Two months later, the linear opacity disappeared coincident with a complete posterior vitreous detachment. The MH was closed by vitrectomy with peeling of the internal limiting membrane. Optical coherence tomography identified an unusual ophthalmoscopic presentation of a preretinal opacity as a part of laminated vitreous cortex associated with a "can-opener" MH.
