choroidal folds

choroidal folds 

A condition characterized by lines, grooves or striae in the posterior fundus. Clinically they appear as alternating light and dark lines possibly corresponding to folds in Bruch's membrane and the retinal pigment epithelium. They are most easily seen with fluorescein angiography. They may occur as a result of a retrobulbar tumour, choroidal tumour, posterior scleritis, ocular hypotony, in hyperopic eyes, or without any discernible cause. See cavernous haemangioma.
