Optical coherence tomography of chorioretinal and choroidal folds

PURPOSE: To report the optical coherence tomography (OCT) findings in cases of chorioretinal and choroidal folds. METHODS: Eight subjects with folds of the fundus of the eye were examined with fundus photography, fluorescein angiography, B-scan ultrasonography and Stratus OCT. RESULTS: 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. CONCLUSIONS: Scanning by OCT can differentiate chorioretinal folds from choroidal folds and reveal the relationships between the folds and the posterior vitreous surface.
