Guarding Sight: Traumatic Cataract Following Reflexive Self-Defense in a Teenager

Traumatic cataract typically results from blunt or penetrating ocular injuries. However, cataract formation due to reflexive act of self-defense is exceptionally rare. We present the case of a 16-year-old boy who sustained trauma to his left eye while shielding himself during an altercation. The injury led to rupture of the anterior lens capsule and dense cataract formation. His best corrected visual acuity (BCVA) was counting fingers in the affected eye. Examination revealed circumciliary congestion, a corneal laceration, a Grade 4 anterior chamber reaction, a ruptured anterior lens capsule, and a white, opacified lens. Lens aspiration with in-the-bag intraocular lens (IOL) implantation was performed. Postoperatively, the patient regained 6/6 visual acuity, which remained stable over monthly follow-ups. This case underscores the importance of prompt diagnosis, timely surgical intervention, and patient education in preventing vision loss due to trauma.
