Macular thickness after cataract surgery with intracameral cefuroxime.

PURPOSE: To determine whether the use of prophylactic intracameral cefuroxime during phacoemulsification cataract surgery is associated with increased macular thickening in the postoperative period. SETTING: Hull and East Yorkshire Eye Hospital, Hull, United Kingdom. METHODS: In this prospective randomized double-masked clinical study, the study group received 1 mg of intracameral cefuroxime and the control group received intracameral balanced salt solution only. Ocular coherence tomography was performed 5 (+/-1) weeks after surgery. RESULTS: Intracameral cefuroxime did not have a statistically significant effect on postoperative macular thickness compared with nonadministration of intracameral antibacterials. All patients in both groups achieved a postoperative best corrected visual acuity of 6/9 or better. CONCLUSION: Use of 1 mg of intracameral cefuroxime was not associated with increased macular thickness 4 weeks to 6 weeks postoperatively.

Increased ocular pulse amplitude revealing aortic regurgitation.

PURPOSE: To report a case in which observation of increased ocular pulse amplitude (OPA) estimates in both eyes lead to a diagnosis of, and was presumably due to, aortic regurgitation. DESIGN: Case report. METHODS: An incidental finding of high OPA estimates in both eyes lead to a finding of widened arterial pulse pressure and aortic regurgitation. OPA estimates were taken after aortic valve surgery when arterial pulse pressure was normal. RESULTS: OPA estimates were 9 mm Hg in both eyes when arterial pulse pressure was high and 3 mm Hg in each eye when normal. CONCLUSION: Widened arterial pulse pressure may lead to increased OPA.
