Retrozonular space
Spatium retrozonulare
Definition
The retrozonular space (a.k.a. the Bergers space or the retrolental space) is a small potential space located immediately behind the lens. It lies between the posterior capsule of the lens anteriorly and the anterior hyaloid membrane of the vitreous body posteriorly.
Peripherally, the space is bounded by Wiegers ligament (hyaloideo-capsular ligament), that serves as a circular annular attachment between the anterior hyaloid membrane and the posterior lens capsule. This ligament helps maintain the close anatomical relationship between the lens and the anterior vitreous face. Centrally, however, the attachment is absent, thereby creating the retrozonular space.
Clinical correlate
Although, the retrozonular space is a potential plane between the posterior lens capsule and the anterior vitreous face, and is normally collapsed, it becomes important during ophthalmic conditions affecting the lens-vitreous interface. For instance, in cataract surgery, disruption of Wiegers ligament may open the retrozonular space, allowing prolapse of the vitreous body into the anterior segment.
