Abstract

Chorioretinal folds may be observed in many choroidal or retinal diseases. In age-related macular degeneration, they are usually associated with retraction of a neovascular membrane and a typically radial pattern of the folds can be seen. In this disease, pigment epithelium folds were recently described. Their clinical and angiographical characteristics are different from chorioretinal folds and the two diseases should not be confused. A 74-old patient presented, in the left eye, with sub foveal new vessels situated at the center of a pigment epithelial detachment (PED). Radial chorioretinal folds surrounded the PED, as frequently observed during follow-up in subretinal neovascular membranes. Nevertheless, right eye fundus examination revealed roughly horizontal, regular and parallel chorioretinal folds. Ultrasonography demonstrated characteristics of idiopathic chorioretinal folds: flattening and thickening of the posterior sclera and choroid. No sign of posterior scleritis was found. These ultrasonographic elements were observed in the left eye away from the central neovascular membrane. The chorioretinal folds therefore seemed to be idiopathic, in a hyperopic patient. The shape of the folds was modified in one eye by a subfoveal neovascular membrane. Chorioretinal folds may occur in different retinal diseases. The associations with many different aetiologies with modification of the shape of the folds, as described in this clinical case, should be emphasized.
