Purpose: To determine the incidence and risk factors for late-onset ocular hypertension (LOH) after vitrectomy. Methods: From the electronic medical records of consecutive patients who underwent primary vitrectomy, from January 2010 to December 2015, at 5 tertiary vitreoretinal centers in Italy, patient demographics, systemic, ophthalmic, operative, and postoperative data were drawn. Main outcome measure was the presence of LOH, defined as intraocular pressure >21 mmHg detected more than 2 months after vitrectomy on at least 2 consecutive visits. Results: Among 6,048 patients, LOH was found in 294 (4.9%) vitrectomized eyes and in 87 (1.4%) fellow eyes, (chi square; P < 0.001). Multivariable logistic regression showed that significant risk factors for developing LOH included intraoperative triamcinolone use (odds ratio [OR], 7.62; P < 0.001), longer axial length (OR, 1.55; P = 3.023), preoperative higher intraocular pressure (OR, 1.81; P = 0.003), and postvitrectomy pseudophakic/aphakic status (OR, 2.04; P < 0.001). Decision-tree analysis showed that the stronger predictor of LOH was intraoperative triamcinolone use (P < 0.001). Secondary predictors were a preoperative intraocular pressure more than 15 mmHg (P < 0.001) in eyes that use triamcinolone, and postvitrectomy pseudophakic/aphakic status (P = 0.007) in eyes that did not use triamcinolone. Conclusion: Late-onset ocular hypertension occurred in 4.9% of vitrectomized eyes. The main risk factors were intraoperative use of triamcinolone and postvitrectomy pseudophakic/aphakic status.
