Swept-source optical coherence tomography imaging of the cortical vitreous and the vitreoretinal interface in proliferative diabetic retinopathy: Assessment of vitreoschisis, neovascularisation and the internal limiting membrane

摘要

Anomalous posterior vitreous detachment leads to shrinkage of the inner vitreous with the outer precortical vitreous cortex remaining attached to the macula and retina, resulting in vitreoschisis. Sebag and coworkers have reported vitreoschisis in macular disorders, and vitreoschisis has been demonstrated using ultrasonography and histopathology. Swept-source OCT (SS-OCT) is a new imaging technology (Atlantis DRI-OCT-1, Topcon, Japan). We demonstrate for the first time in vivo the microstructural tomographic features of and spatial vitreoretinal relationships between vitreoschisis, retinal and optic nerve head neovascularisation, detachment of the internal limiting membrane (ILM) and traction on the neuroretina in proliferative diabetic retinopathy (PDR).
