What is the main etiology of Iridodialysis?

• A. Trauma
• B. Infection
• C. Ischemia
• D. Degeneration

Answer: (A)

Trauma is the main cause of iridodialysis. This condition is a tear at the iris root where it attaches to the ciliary body, most commonly from blunt eye trauma. The sudden deceleration and force create a shearing effect across the iris insertion, causing the iris to separate from its origin. Infections, ischemia, or degeneration don’t produce this mechanical detachment of the iris root; they affect tissue health or blood supply instead, making trauma the correct etiology for iridodialysis.
