Vitreous cortex splitting in cases of vitreomacular traction syndrome.

The authors report four cases of vitreomacular traction syndrome with splitting of the posterior vitreous cortex. Spectral-domain optical coherence tomography (SD-OCT) was performed consecutively in 35 patients with vitreomacular traction syndrome between June 2007 and February 2011. SD-OCT showed perifoveal posterior vitreous detachment with splitting of the posterior vitreous cortex in 4 of 35 eyes (at the fovea in 1 eye and the perifovea in 3 eyes). The separated cortex of the posterior lamella adhered to the retina in all 4 eyes. The posterior vitreous cortex may split at the macular area in cases of vitreomacular traction syndrome.
