Lens dislocation

Background

Lens dislocation or subluxation is any movement of the lens of the eye either anteriorly or posteriorly from its socket attached to the suspensory ligaments. This typically occurs due to blunt trauma to the eye, and is commonly seen in conjunction with a hyphema and/or a vitrious hemorrhage. There are conditions that predispose patients to lens dislocations from even minor traumatic events, such as Marfans syndrome (classically lens is upwards and outwards), Homocystinuria (classically lens is downwards and inwards), and Ehlers–Danlos syndrome. A emergent complication of a lens dislocation is acute angle closure glaucoma, and occurs because of disruption of the iris and the cornea.
