Choroidal Folds

Dobras de coroide

“…The darker region corresponds to the depressed portion of the fold and is called the valley (4,5) . Initially they are thin and mild, similar to arrows or blood vessels (4) , and may be difficult to notice on ophthalmoscopy (1) . Over time they become larger and more pigmented, which facilitates identification (1,4) .…”

“…Choroidal folds are not an unusual finding on fundus examination (5) and are the most prevalent finding in patients with orbital tumour (6) . They are usually asymptomatic but may cause visual disturbances such as hyperopia, astigmatism, and metamorphopsia (1,2,5) . Such symptoms are most evident in patients with recent folds of sudden onset (1,2) .…”

“…horoidal folds are grooves in the retinal pigment epithelium (RPE), Bruch's membrane, the inner portion of the choriocapillaris and, in some instances, the neurosensory retina, in which case they are called chorioretinal folds (1)(2)(3) . They were first described by Nettleship in 1884 as "peculiar choroidal lines" in a patient with papilledema secondary to an orbital mass lesion (1,4,5) .…”
