Lens dislocation

Presentation

Middle aged patient, who presented to the Emergency Room department with ocular trauma from a wooden log.

Patient Data

Gender: Male
CT

Unenhanced axial CT scan shows complete posterior dislocation of the right lens. 

Case Discussion

Blunt trauma typically displaces the cornea and anterior sclera posteriorly making a deformation of the globe.The deformation causes the complete (in these case) or partial rupture of zonular attachments. After complete rupture, the lens dislocates almost always posteriorly, but less commonly anteriorly.

Nontraumatic lens dislocation can occur in systemic connective tissue disorders, e.g. Marfan syndrome, Ehlers-Danlos syndrome and homocystinuria.
