To evaluate outcomes of peripheral iridotomy (PI) for initial management of primary angle closure suspects (PACS), chronic primary angle closure (CPAC), and chronic primary angle closure glaucoma (CPACG). <jats:italic>Patients and Methods<\/jats:italic>. Seventy-nine eyes with PACS, CPAC, or CPACG and better than 20\/50 visual acuity that underwent PI as initial management were included. Eyes with previous acute angle closure attacks, laser trabeculoplasties, surgeries, or intraocular injections were excluded. Additional treatments, glaucomatous progression, intraocular pressure, visual acuity, and the number of medications were evaluated. <jats:italic>Results<\/jats:italic>. The mean followup was  months (range 13.8\u2013150.6 months). Sixty-eight eyes (86.1%) underwent additional medical, laser, or surgical treatment. Forty eyes (50.6%) underwent lens extraction due to reduced visual acuity. The mean 10\u00d7\u2009logMAR visual acuity score for all patients significantly declined from  at baseline to  (, ) at the last followup. <jats:italic>Conclusions<\/jats:italic>. Most patients who undergo PI for CPAC spectrum will require additional intervention for either IOP lowering or improvement of visual acuity. This suggests that a procedure that not only deepens the angle but also lowers IOP and improves visual acuity would be desirable as further intervention could be avoided. Evaluation of techniques that achieve all 3 goals is warranted.<\/jats:p>","DOI":"10.1155\/2013\/828972","type":"journal-article","created":{"date-parts":[[2013,6,26]],"date-time":"2013-06-26T21:02:48Z","timestamp":1372280568000},"page":"1-9","source":"Crossref","is-referenced-by-count":12,"title":["Clinical Outcomes of Peripheral Iridotomy in Patients with the Spectrum of Chronic Primary Angle Closure"],"prefix":"10.1155","volume":"2013","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7921-4153","authenticated-orcid":true,"given":"Ricardo J.","family":"Cumba","sequence":"first","affiliation":[{"name":"Ruiz Department of Ophthalmology and Visual Science, The University of Texas Medical School at Houston, 6431 Fannin Street, MSB 7.024, Houston, TX 77030, USA"},{"name":"Ophthalmology Department, Medical School, University of Puerto Rico, Medical Science Campus, P.O.
