Abstract: :
Purpose: To determine whether the presence or absence of diabetes and/or hypertension was a risk factor for intraoperative posterior capsule rupture with or without vitreous loss during cataract phacoemulsification. Methods: Patient data from 1009 phacoemulsifications performed from 1995 to 2001 at the University of Chicago Hospitals were reviewed and analyzed for the presence of diabetes, hypertension and intraoperative posterior capsule rupture with or without vitreous loss. Results: Of the 1009 eyes, 291 (28.9%) were from patients with a history of diabetes, and 552 (54.8%) were from patients with a history of hypertension. Intraoperative posterior capsule rupture occurred in 70 (6.9%) eyes, and intraoperative vitreous loss occurred in 38 (3.8%) eyes. There was a statistically significant increased rate of intraoperative posterior capsule rupture in patients with a history of hypertension compared to those without hypertension (8.0% vs. 5.7%, p < 0.0001 using chi-squared analysis). There was also an increased rate of vitreous loss in patients with a history of hypertension, compared to those without hypertension (4.7% vs 2.6%), although this difference was not significant. Diabetic patients also had a higher rate of intraoperative posterior capsular rupture compared to nondiabetic patients (8.6% vs 6.3%), although this was difference was not significant. There was also a higher rate of vitreous loss in diabetic patients, compared to nondiabetic patients (4.5% vs 3.5%), although this difference was not significant. Conclusion: The risk of intraoperative posterior capsular rupture during cataract phacoemulsification may be increased in patients with a history of hypertension. The presence of diabetes does not appear to be an independent risk factor for posterior capsular rupture. Neither diabetes nor hypertension appears to be an independent risk factor for intraoperative vitreous loss.
