Purpose: To report an unusual preretinal opacity associated with an idiopathic macular hole (MH) that was identified by optical coherence tomography.
Design: Observational case report.
Methods: A 59-year-old woman with a preretinal linear opacity running across an MH was examined by optical coherence tomography.
Results: 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.
Conclusions: 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.
