Disinsertion of the iris root from the ciliary body is known as ____________.

• A. Iris Coloboma
• B. Iridodialysis
• C. Aniridia
• D. Pigment Tear

Answer: (B)

Iridodialysis is the separation of the iris root from the ciliary body, usually following blunt trauma. This detachment at the iris root leaves part of the iris no longer anchored, which can distort the pupil and may be associated with bleeding into the anterior chamber. It’s a distinct condition from other iris abnormalities: iris coloboma is a congenital notch due to incomplete closure of the fetal fissure, aniridia is the absence of the iris, and a pigment tear describes a different, non-iris-root disinsertion issue.
