Folding of the choroid, Bruch's membrane, and the overlying retina occurs in a variety of ocular and orbital diseases and after certain surgical procedures. The etiology of the folding is explained, using the principles of deformation of materials and by considering the biomechanical properties of the choroid and sclera. Choroidal folds are likely to develop in association with any intra- or extraocular process that induces sufficient compressive stress within the choroid, Bruch's membrane, and retina to force these tissues to buckle. A detailed explanation of the pathogenesis of folding is presented in various clinical settings.
脉络膜、布鲁赫膜及上方视网膜的折叠发生于多种眼部和眼眶疾病以及某些外科手术后。运用材料变形原理并考虑脉络膜和巩膜的生物力学特性来解释折叠的病因。脉络膜折叠很可能与任何引起脉络膜、布鲁赫膜及视网膜内足够大的压应力从而迫使这些组织发生弯曲的眼内或眼外病变相关。本文针对不同临床情况详细阐述了折叠的发病机制。
