Change in Ocular Flora Resistance From Repeated Topical Antibiotic Use

Increased Drug Resistance Clinical Trial

Official title: Antibiotic Resistance of Ocular Surface Flora After Continued Use of Topical Antibiotics Post Intravitreal Injections

Status Completed

Clinical Trial Summary

The purpose of this study is to determine if antibiotic resistance of the ocular surface flora to the 4th generation fluoroquinolones will increase after repeated use of topical antibiotics for three days post intravitreal injection.

Clinical Trial Description

Treatment with intravitreal (IVT) injections has increased during the last several years as evidence has accumulated demonstrating the efficacy of anti-vascular endothelial growth factor agents in the treatment of neovascular age-related macular degeneration (AMD) and various retinal vascular diseases.

Although IVT injections are generally safe, infectious endophthalmitis is a rare but devastating complication, and the risk of morbidity and vision loss from endophthalmitis is high. The objective is to examine the change in antibiotic resistance of ocular surface flora with repeated prophylactic use of antibiotics after IVT injection for AMD.
