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.
Increased Drug Resistance
Infection Resistant to Quinolones and Fluoroquinolones
||Observational Model: Case Control
Time Perspective: Prospective
||Antibiotic Resistance of Ocular Surface Flora After Continued Use of Topical Antibiotics Post Intravitreal Injections
Primary Outcome Measures:
- ocular flora resistance to 4th generation fluoroquinolone [ Time Frame: 1 year ] [ Designated as safety issue: No ]
Outcome will examine the change in amount, type and antibiotic resistance profile of ocular surface flora over the 3 months. Charcoal swab of the conjunctiva will be cultured, organisms grown will be identified and resistance to moxifloxacin will be quantified by minimal inhibitory resistance (MIC).
