Brief summary
This is a research study to evaluate the effects of repeated intravitreal injections on bacteria around the eye.
Detailed description
The primary objective of this study is to determine whether conjunctival bacterial flora are altered and/or demonstrate increasing antibiotic resistance after serial intravitreal injections when a prophylactic topical antibiotic is used pre- and post-injection compared to when they are not used.
Interventions
Patients will either receive a drop of topical antibiotic before and after the intravitral injection or no topical antibiotics (only typical prep with betadine).

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Determine if conj bacterial flora demonstrates increased antibiotic resistance if topical antibiotic used pre and post injection vs not used. | Prior to each of your eye injections for the first 4 injections and continue through the completion of your fourth injection, an anticipated maximum of 6 months. | Evaluating the effects of repeated use of iodine drops with or without antibiotic eye drops on bacteria on the eye surface in patients undergoing injections in the eye to determine if conjunctival bacterial floar are altered or demonstate increasing antibiotic resistance. |
