Optical coherence tomography of chorioretinal and choroidal folds.

To report the optical coherence tomography (OCT) findings in cases of chorioretinal and choroidal folds.Eight subjects with folds of the fundus of the eye were examined with fundus photography, fluorescein angiography, B-scan ultrasonography and Stratus OCT.Two types patterns were found on OCT. Five cases showed undulating retinal as well as retinal pigment epithelial lines of normal thickness; these were defined as chorioretinal folds. The posterior vitreous surface often adhered to the crests of the folds only. Three cases exhibited a wavy appearance of the retinal pigment epithelium and a flat retinal surface; these were classified as choroidal folds.Scanning by OCT can differentiate chorioretinal folds from choroidal folds and reveal the relationships between the folds and the posterior vitreous surface.
