Evaluation of aqueous outflow facility in patients with high intraocular pressure after cataract surgery
Laurell C-G; Lydahl EOphthalmic Surgery Lasers and Imaging 2006; 37: 476-480
BACKGROUND AND OBJECTIVE: To study whether patients with a marked elevation of intraocular pressure (IOP) the day after cataract surgery may have a chronically impaired aqueous outflow. PATIENTS AND METHODS: In 128 consecutive patients, IOP was measured both preoperatively and the day after phacoemulsification and intraocular lens implantation. In the late postoperative period, aqueous outflow facility (C-value) was measured with pneumatonography in patients (n = 7) who experienced a postoperative IOP increase of at least 20 mmHg and in patients (n = 11) with a difference between preoperative and postoperative IOP of not more than 2 mmHg. RESULTS: Aqueous outflow facility was normal in both groups. Mean C-value was 0.32 ± 0.18 μL/min/mmHg in the hypertensive group and 0.23 ± 0.10 μL/min/mmHg in the normotensive group. The difference was not statistically significant (P = .20). CONCLUSIONS: Patients with marked IOP elevation the day after cataract surgery do not seem to have a chronically impaired aqueous outflow facility compared with normotensive patients.
