LOPEZ LANTIGUA, Naivy et al. Effectiveness of the Nd: YAG laser iridectomy in glaucoma caused by primary angle closing. Rev.Med.Electrón. [online]. 2015, vol.37, n.6, pp. 559-569. ISSN 1684-1824.

Background: glaucoma management includes the opportune surgical decision. Laser iridectomy could be a surgical solution, or may be used as prophylaxis of an acute event that could lead to blindness. Aim: describing the Nd:YAG laser iridectomy effectiveness in patients with glaucoma caused by primary angular closing. Materials and methods: we carried out a longitudinal, prospective, descriptive study. The universe was formed by 36 eyes subjected to peripheral iridectomy with Nd:Yag laser, in the Teaching Clinic Surgical Hospital “Comandante Faustino Pérez Hernández”, from January 2014 until  January 2015. Outcomes: all the eyes showed central anterior camera depths less than 2.5 mm. In the post-surgery period, depth improved in 58.3 % of the cases. Pre-surgery goniometry showed up to the anterior trabecula in 66.7 % of the cases, and 6 eyes (16.7 %) presented totally closed angles. In the post-surgery period, 66.7 % of the eyes showed up to sclerar spur or band. 14 eyes (38.9 %) answered to the procedure without any other treatment, all of them with diagnosis according to the procedure of chance assignation; the rest needed any other extra therapy. Conclusions: it was showed that iridectomy is a choice procedure in cases of glaucoma caused by primary angular closure, but its effectiveness is limited.
