Plateau Iris Syndrome

Axial portion of the anterior chamber is of normal depth and an iridectomy is present at 11 o’clock. The plane of iris is vertical, and the iris root undergoes a knee-shaped bend (insert lower right) in the extreme periphery, cauing a sudden narrowing of the angle in the presence of a patient iridectomy. Insert upper right shows a closed angle in spite of a deep central anterior chamber.
