Plain-English summary
A study looked at 78 dogs that had cataract surgery to see how their eye angles affected the risk of developing high eye pressure and glaucoma afterward. They found that older dogs and female dogs were more likely to have these issues, especially if the surgery took longer or if the surgeon was less experienced. Dogs with more open eye angles had a lower chance of developing glaucoma that didn't respond to medication. Understanding these factors can help vets better predict and manage potential complications after cataract surgery.

Abstract
PURPOSE: To investigate the relationship between gonioscopic iridocorneal angle (ICA) morphology and the incidence of postoperative ocular hypertension (POH) and postoperative glaucoma in dogs undergoing cataract surgery. ANIMALS STUDIED: Retrospective analysis of 138 eyes of 78 canine patients who underwent phacoemulsification at North Carolina State University from December 1, 2015 through April 30, 2017. METHODS: Medical records of all phacoemulsification patients with preoperative RetCam gonioscopic images were reviewed for preoperative, intraoperative, and postoperative variables. Gonioscopic angle indices were calculated using a novel (ZibWest) angle grading system, and these indices were analyzed for outcome-related significance. RESULTS: Increased surgeon experience was associated with increased probability of POH and vision loss. Higher average ZibWest Angle indices (ie, more open angles with less pectinate ligament dysplasia/ abnormality) were associated with a significantly decreased probability of medically unresponsive glaucoma. Increased patient age was significantly associated with an increased probability of both postoperative glaucoma and vision loss. Female dogs were significantly more likely to experience postoperative glaucoma compared to male dogs. Increased surgery time was significantly associated with increased probability of vision loss. CONCLUSIONS: The ZibWest angle index may predict increased risk for developing medically unresponsive glaucoma with cataract surgery. Female sex, and increased patient age, surgical time, and surgeon experience were associated with increased postoperative morbidity.
