Diagnosis, signalment, concurrent ocular disease, medications, IOP, visual status, and additional procedures were recorded. Treatment failure was defined as horses with IOP >\u200930\u2009mmHg resulting in phthisis bulbi or requiring a procedure or enucleation.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n Secondary glaucoma was diagnosed in 8\/12 (67%) eyes and primary glaucoma in 4\/12 (33%) eyes. IOP was <\u200930\u2009mmHg in 7\/12 (58%) eyes after treatment with topical CAIs for a median of 28\u2009days. Episcleral brinzolamide implants were placed in 7\/12 eyes after a median of 58\u2009days of medical therapy. Treatment failure occurred in 3\/7 horses (43%) receiving brinzolamide implants at a median of 189\u2009days and in 4\/5 medical therapy\u2010only horses (80%) at a median of 51\u2009days. While 6\/12 eyes (50%) were visual at last follow\u2010up (median of 161\u2009days), enucleation was the final outcome in 10\/12 (83%) eyes.<\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n Topical CAIs appear to result in temporary IOP control in a subset of horses, though some horses may be refractory. Episcleral brinzolamide implants may extend IOP control in horses with glaucoma, but prognosis for vision remains guarded and further optimization is needed.<\/jats:p>\n <\/jats:sec>","DOI":"10.1111\/vop.70086","type":"journal-article","created":{"date-parts":[[2025,9,23]],"date-time":"2025-09-23T03:31:45Z","timestamp":1758598305000},"page":"977-982","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Retrospective Assessment of Carbonic Anhydrase Inhibitors in Topical or Episcleral Implant Form for the Treatment of Equine Glaucoma"],"prefix":"10.1111","volume":"28","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4116-2909","authenticated-orcid":false,"given":"Emily K.","family":"Tucker\u2010Retter","sequence":"first","affiliation":[{"name":"Department of Clinical Sciences College of Veterinary Medicine, North Carolina State University Raleigh North Carolina USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maya","family":"Yamagata","sequence":"additional","affiliation":[{"name":"Hawaii Veterinary Vision, Inc.
