This retrospective review reports on patients who underwent glaucoma drainage implant (GDI) surgery and had baseline intraocular pressure (IOP) of \u226418\u2009mmHg with at least one year of follow-up. Methods. Clinical data of 67 eyes of 67 patients were collected from patients\u2019 charts, and the outcomes of GDI were evaluated until 7\u2009years. GDI failure was defined as IOP reduction of less than 20% from the baseline at two consecutive visits three months after surgery, decline to no light perception, or if additional glaucoma surgery was performed. Results. The average age was 65.9\u2009\u00b1\u200913.2\u2009years. Most cases were male (52.2%), White (53.7%), and had primary open-angle glaucoma (62.7%). Forty-four eyes had prior glaucoma surgery (68.6%) and 46 (68.6%) had severe glaucoma. Though postoperative (postop) IOP changes were insignificant, the average postop number of medications dropped from 2.4\u2009\u00b1\u20091.4 to 1.9\u2009\u00b1\u20091.2 medications two years after surgery (<jats:inline-formula><a:math xmlns:a=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M1\"><a:mi>p<\/a:mi><a:mo>=<\/a:mo><a:mn>0.0451<\/a:mn><\/a:math><\/jats:inline-formula>). Postop complications (23.9%) included GDI exposure (7.5%), inflammation (4.5%), shallow anterior chamber (4.5%), and strabismus (1.5%). Hypotony was observed in 4 eyes (5.9%), none of which developed hypotony maculopathy. The cumulative one-year failure rate was 56.7%, most of which were due to failure to lower IOP. Conclusion. In patients with baseline IOP \u226418\u2009mmHg who had GDI surgery, though the change in IOP was not statistically significant, the number of medications dropped and visual field progression slowed in a subset of patients with adequate perimetric data. Due to a relatively high rate of complications and limited effectiveness in lowering IOP, GDI should be cautiously used in these eyes.<\/jats:p>","DOI":"10.1155\/2024\/6624021","type":"journal-article","created":{"date-parts":[[2024,1,24]],"date-time":"2024-01-24T21:50:08Z","timestamp":1706133008000},"page":"1-7","source":"Crossref","is-referenced-by-count":2,"title":["Long-Term Surgical Outcomes of Glaucoma Drainage Implants in Eyes with Preoperative Intraocular Pressure Less than 19\u2009mmHg"],"prefix":"10.1155","volume":"2024","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9541-1915","authenticated-orcid":true,"given":"Shahin","family":"Hallaj","sequence":"first","affiliation":[{"name":"Glaucoma Service, Wills Eye Hospital, Thomas Jefferson University, Philadelphia, PA 19107, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5194-0746","authenticated-orcid":true,"given":"Jae-Chiang","family":"Wong","sequence":"additional","affiliation":[{"name":"Glaucoma Service, Wills Eye Hospital, Thomas Jefferson University, Philadelphia, PA 19107, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lauren E.","family":"Hock","sequence":"additional","affiliation":[{"name":"Glaucoma Service, Wills Eye Hospital, Thomas Jefferson University, Philadelphia, PA 19107, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5836-5753","authenticated-orcid":true,"given":"Natasha Nayak","family":"Kolomeyer","sequence":"additional","affiliation":[{"name":"Glaucoma Service, Wills Eye Hospital, Thomas Jefferson University, Philadelphia, PA 19107, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0765-8337","authenticated-orcid":true,"given":"Aakriti G.","family":"Shukla","sequence":"additional","affiliation":[{"name":"Glaucoma Service, Wills Eye Hospital, Thomas Jefferson University, Philadelphia, PA 19107, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael J.","family":"Pro","sequence":"additional","affiliation":[{"name":"Glaucoma Service, Wills Eye Hospital, Thomas Jefferson University, Philadelphia, PA 19107, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marlene R.","family":"Moster","sequence":"additional","affiliation":[{"name":"Glaucoma Service, Wills Eye Hospital, Thomas Jefferson University, Philadelphia, PA 19107, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8251-6750","authenticated-orcid":true,"given":"Jonathan S.","family":"Myers","sequence":"additional","affiliation":[{"name":"Glaucoma Service, Wills Eye Hospital, Thomas Jefferson University, Philadelphia, PA 19107, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Reza","family":"Razeghinejad","sequence":"additional","affiliation":[{"name":"Glaucoma Service, Wills Eye Hospital, Thomas Jefferson University, Philadelphia, PA 19107, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daniel","family":"Lee","sequence":"additional","affiliation":[{"name":"Glaucoma Service, Wills Eye Hospital, Thomas Jefferson University, Philadelphia, PA 19107, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"crossref","first-page":"302","DOI":"10.3129\/i08-061","article-title":"Relationships among systemic blood pressure, intraocular pressure, and open-angle glaucoma","volume":"43","author":"S.
