All patients underwent IOP measurement preoperatively and at 1 day, 1 week, and 1, 3, and 6 months postoperatively. SS AS-OCT was performed in all subjects preoperatively and 1 month postoperatively. All participants were divided into two groups depending on the presence of glaucomatous optic disc or visual field damage (group A, PAC suspect or PAC; group B, PAC glaucoma). The changes in IOP and anterior chamber angle parameters of SS AS-OCT of each group were compared. Regression analysis was performed to find factors associated with the degree of IOP reduction after lens extraction.Results: Preoperatively, there was no significant difference in IOP between the two groups (16.3 \u00b1 2.5 mmHg vs. 16.9 \u00b1 3.2 mmHg, p = 0.297), but the number of glaucoma medications used was greater in group B (0.6 \u00b1 1.0 vs. 2.0 \u00b1 0.9, p &lt; 0.001). Postoperatively, IOP was not significantly different, but the number of medications used was greater in group B (0.2 \u00b1 0.7 vs. 0.9 \u00b1 0.8, p &lt; 0.001). Anterior chamber angle parameters including angle opening distance and trabecular-iris angle had a greater increase in group B after lens extraction. However, the residual iridotrabecular contact (ITC) index was significantly greater in group B (5.6 \u00b1 7.0 vs 10.7 \u00b1 12.1, p = 0.014). A greater change in the ITC index was related to a greater degree of IOP reduction (\u03b2 coefficient, 0.429; p &lt; 0.001).Conclusions: Eyes with PAC glaucoma had a greater residual ITC index after lens extraction compared with eyes of other PACD spectrum and required a greater number of glaucoma medications to maintain a similar level of IOP.<\/jats:p>","DOI":"10.3341\/kjo.2024.0014","type":"journal-article","created":{"date-parts":[[2024,8,19]],"date-time":"2024-08-19T01:14:21Z","timestamp":1724030061000},"page":"342-353","update-policy":"https:\/\/doi.org\/10.3341\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Changes in Iridotrabecular Contact and Intraocular Pressure after Phacoemulsification in Primary Angle-Closure Disease Spectrum"],"prefix":"10.3341","volume":"38","author":[{"given":"Hoon Il","family":"Choi","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Woo Keun","family":"Song","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kyung Rim","family":"Sung","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1893","reference":[{"key":"ref1","first-page":"e1221","volume-title":"Global causes of blindness and distance vision impairment 1990\u20132020 a systematic review and meta-analysis","author":"Flaxman","year":"2017"},{"key":"ref2","first-page":"844","volume-title":"Global data on visual impairment in the year 2002","author":"Resnikoff","year":"2004"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1016\/j.survophthal.2013.09.003"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1016\/s0161-6420(02)01275-7"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1136\/bjo.86.2.238"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1016\/j.ophtha.2013.04.020"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1007\/s00417-012-2158-6"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1097\/ijg.0000000000001537"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajo.2022.12.023"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.3390\/jcm11092557"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0199157"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1016\/j.ophtha.2015.10.049"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1016\/j.ogla.2020.11.006"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1002\/14651858.cd005555.pub3"},{"key":"ref15","first-page":"223","volume-title":"Surgical treatment for primary angle closure-glaucoma: a meta analysis","author":"Deng","year":"2011"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.1136\/bjo.87.4.399"},{"key":"ref17","doi-asserted-by":"publisher","DOI":"10.1097\/00061198-200006000-00002"},{"key":"ref18","first-page":"13498","volume-title":"Clinical outcome of phacoemulsification combined with intraocular lens implantation for primary angle closure\/glaucoma (PAC\/ PACG) with cataract","author":"He","year":"2021"},{"key":"ref19","doi-asserted-by":"publisher","DOI":"10.1136\/bjophthalmol-2021-320453"}],"container-title":["Korean Journal of Ophthalmology"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/ekjo.org\/upload\/pdf\/kjo-2024-0014.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/ekjo.org\/journal\/view.php?doi=10.3341\/kjo.2024.0014","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/ekjo.org\/upload\/pdf\/kjo-2024-0014.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,2,5]],"date-time":"2025-02-05T08:06:43Z","timestamp":1738742803000},"score":1,"resource":{"primary":{"URL":"http:\/\/ekjo.org\/journal\/view.php?doi=10.3341\/kjo.2024.0014"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024,10,5]]},"references-count":19,"journal-issue":{"issue":"5","published-print":{"date-parts":[[2024,10]]}},"URL":"https:\/\/doi.org\/10.3341\/kjo.2024.0014","relation":{},"ISSN":["1011-8942","2092-9382"],"issn-type":[{"type":"print","value":"1011-8942"},{"type":"electronic","value":"2092-9382"}],"subject":[],"published":{"date-parts":[[2024,10,5]]},"assertion":[{"value":"2024-02-01","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2024-08-02","order":1,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2024-08-16","order":2,"name":"published","label":"Published online","group":{"name":"publication_history","label":"Publication History"}},{"value":"2024-10-05","order":3,"name":"published","label":"Print publication","group":{"name":"publication_history","label":"Publication History"}}]}}
