Intermittent acute angle closure glaucoma and chronic angle closure following topiramate use with plateau iris configuration

This is a case report describing recurrent intermittent acute angle closure episodes in the setting of topiramate use in a female suffering from migraines. Despite laser peripheral iridotomy placement for the pupillary block component, and the discontinuation of topiramate, the acute angle closure did not resolve in the left eye with chronic angle closure and the patient required urgent trabeculectomy. The right eye responded to laser peripheral iridotomy immediately and further improved after the cessation of topiramate. While secondary angle closure glaucoma due to topiramate use has been widely reported, its effects in patients with underlying primary angle closure glaucoma have not been discussed. Our report highlights the importance of recognizing the often multifactorial etiology of angle closure glaucoma to help guide clinical management. © 2014 Rajjoub et al

Influence of surgery simulator training on ophthalmology resident phacoemulsification performance

Purpose: To determine whether the use of an eye-surgery simulator during ophthalmology residency training improves cataract surgery performance. Setting: Department of Ophthalmology, Medical Faculty Associates, George Washington University, Washington, DC, USA. Design: Comparative case series. Methods: Residents were divided into a simulator group and a nonsimulator group based on the inclusion or absence of the eye-surgery simulator in residency training. Consecutive resident cataract surgeries with the same attending surgeon were retrospectively reviewed. The phaco time and percentage power and intraoperative complications in each case were recorded. The adjusted phaco time in each case was calculated. Results: The study reviewed 592 surgeries. The mean values for phaco time, percentage phaco power, adjusted phaco time, complication rates, and complication grade were 1.88 minutes (range 0.11 to 7.20 minutes), 25.32% (range 2.2% to 50.0%), 47.58 minutes (range 0.24 to 280.80 minutes), 0.04, and 2.33, respectively, in the simulator group (n = 17) and 2.41 minutes (range 0.04 to 8.33 minutes), 28.19% (range 8.0% to 70.0%), 71.85 minutes (range 0.32 to 583.10 minutes), 0.06, and 2.47, respectively, in the nonsimulator group (n = 25). The Student t tests showed a statistically significant between-group difference in mean phaco time (P\u3c.002), adjusted phaco time (P\u3c.0001), and percentage phaco power (P\u3c.0001). Regression analysis showed a significantly steeper slope of improvement in mean phaco time and power in the nonsimulator group than in the simulator group (P\u3c.0001). Conclusions: Residents who trained using the simulator had shorter phaco times, lower percentage powers, fewer intraoperative complications, and a shorter learning curve.
