A rare orbital cyst due to traumatic lens dislocation

Abstract

<br>Lens dislocation into the subconjunctival or subtenon's space is a rare but known complication of blunt eye trauma. However, lens dislocation into the orbital space has never been reported. Here, we describe a case of orbital cyst caused by traumatic lens dislocation. A 55-year-old man complained of persistent orbital edema and pain in the right eye after ocular evisceration and orbital implant surgery for severe scleral rupture. Computed tomography showed increased soft-tissue density in the infero-temporal orbital space. An orbitotomy and histological examination confirmed that the mass in the orbit was a cyst that formed from the dislocated lens.<br>
