Document Objectives

Identify patients who currently have or are at risk of developing PACG or AACC by using Gonioscopy. Successfully manage AACC. Prevent or reverse angle closure by using laser iridotomy and/or iridoplasty when indicated, and by using incisional iridectomy when necessary to alleviate pupillary block. Confirm by repeat gonioscopy that the angle is open after intervention. If not, consider incisional surgery when laser therapy does not alleviate pupillary block. Identify and manage patients with chronic IOP elevation that persists after iridotomy or iridoplasty. Evaluate the fellow eye for evidence of angle closure or an anatomically narrow angle in AACC, and consider performing a prophylactic iridotomy when indicated. Educate the patient and family members about the characteristics of the disease and involve them in the patient’s management. Also, communicate to family members that they themselves may be at risk of angle closure and should be evaluated.
