Angle-closure glaucoma is characterized by appositional or synechial closure of the anterior chamber angle with glaucomatous field defects that may or may not be associated with a pupillary block. Surgical pupilloplasty with single-pass four-throw technique helps to alleviate the appositional closure along with the breakage of peripheral anterior synechia, thereby increasing the aqueous outflow and decreasing intraocular pressure.
闭角型青光眼的特征是前房角的贴附性或粘连性关闭，并伴有青光眼性视野缺损，这种缺损可能与瞳孔阻滞有关，也可能无关。采用单通道四针技术的手术瞳孔成形术有助于缓解贴附性关闭以及周边前粘连的破裂，从而增加房水流出并降低眼压。
