IOP at the time of UBM imaging and the duration from AGV surgery to UBM imaging were recorded. Histological examination of an enucleated eye removed due to uncontrolled IOP leading to blindness was also conducted.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sc_a4\">\n<jats:title>RESULTS<\/jats:title>\n<jats:p>A significant correlation was observed between IOP and relative reflectivity (Pearson <jats:italic>r<\/jats:italic> = 0.60; <jats:italic>P<\/jats:italic> = .01), and a negative correlation was observed between bleb wall thickness and relative reflectivity (Pearson <jats:italic>r<\/jats:italic> = \u22120.72; <jats:italic>P<\/jats:italic> = .002). No significant correlation was observed between the duration from AGV surgery to UBM imaging and either bleb wall thickness or relative reflectivity, respectively. Histological examination of the enucleated eye revealed collagen-rich fibrous encapsulation of the bleb wall, including myofibroblasts that exhibited positive \u03b1-smooth muscle actin immunostaining.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sc_a5\">\n<jats:title>CLINICAL RELEVANCE<\/jats:title>\n<jats:p>In dogs that underwent AGV surgery, less dense, thick-walled blebs on UBM tended to maintain IOP within the normal range. However, denser, thinner-walled blebs showed IOP levels above the normal range despite the use of antiglaucoma medications. UBM is a useful tool for evaluating bleb characteristics and their influence on IOP regulation after AGV surgery in dogs.<\/jats:p>\n<\/jats:sec>","DOI":"10.2460\/ajvr.24.01.0013","type":"journal-article","created":{"date-parts":[[2024,3,1]],"date-time":"2024-03-01T13:17:33Z","timestamp":1709299053000},"source":"Crossref","is-referenced-by-count":3,"title":["Bleb characteristics assessed by ultrasound biomicroscopy correlate with intraocular pressure after Ahmed glaucoma valve surgery in dogs"],"prefix":"10.2460","volume":"85","author":[{"given":"Songhui","family":"Lee","sequence":"first","affiliation":[{"name":"Department of Veterinary Clinical Sciences, College of Veterinary Medicine and Research Institute for Veterinary Science, Seoul National University, Seoul, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Su An","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Veterinary Clinical Sciences, College of Veterinary Medicine and Research Institute for Veterinary Science, Seoul National University, Seoul, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Du-Min","family":"Go","sequence":"additional","affiliation":[{"name":"Laboratory of Veterinary Pathology, College of Veterinary Medicine and Research Institute for Veterinary Science, Seoul National University, Seoul, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dae-Yong","family":"Kim","sequence":"additional","affiliation":[{"name":"Laboratory of Veterinary Pathology, College of Veterinary Medicine and Research Institute for Veterinary Science, Seoul National University, Seoul, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kangmoon","family":"Seo","sequence":"additional","affiliation":[{"name":"Department of Veterinary Clinical Sciences, College of Veterinary Medicine and Research Institute for Veterinary Science, Seoul National University, Seoul, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Seonmi","family":"Kang","sequence":"additional","affiliation":[{"name":"Department of Veterinary Clinical Sciences, College of Veterinary Medicine and Research Institute for Veterinary Science, Seoul National University, Seoul, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1272","reference":[{"key":"B1","series-title":"Veterinary Ophthalmology","first-page":"1173","article-title":"The canine glaucomas","author":"Plummer CE","year":"2021","unstructured":"Plummer CE, Kom\u00e1romy AM, Gelatt KN.
