White cataract from trauma
Contributor: Andrew Doan, MD, PhD, University of Iowa
During blunt trauma, a variety of forces act on the eye, including coup, contracoup, and anterior-posterior shortening and expansion. These forces can damage the lens capsule, zonules, or both, causing formation of a partial or complete contusion cataract. In some cases, trauma can cause opacification as well as lens dislocation. A perforating or penetrating injury can violate the lens capsule, often resulting in rapid cortical cataract formation at the site of rupture, followed by complete lens opacification.
