Summary

1. Background: Over 1 million intravitreal injections are performed annually in the United States. The most devastating complication related to these injections is endophthalmitis, with an incidence of 0.02 - 0.1% per injection. Techniques aimed at prevention of this complication have been studied, though emergence rates of antibiotic resistant bacteria in a single clinic population comparing antiseptic technique with iodine vs. use of post-injection second generation fluoroquinolones has not been reported in the literature.
2. Objectives: The purpose of the study is to help determine the best way to prevent infection and limit antibiotic resistance in patients receiving eye injections.
3. Procedures Involved (Research Interventions): After the patient is chosen based on inclusion criteria and agrees to participate in the study, exclusion criteria will be reviewed, cognizance will be determined, informed consent and HIPAA compliance forms will be signed. At this point and prior to the instillation of ophthalmic medications, a Rayon swab will be passed along the inferior fornix of the study eye while the patient looks up and the examiner lowers the lower eyelid. The swab will then be used to inoculate chocolate agar and a blood agar culture plates and a glass slide. These will be brought to the FMO microbiology department for culture and Gram stain. All Staphylococcus aureus and coagulase negative Staphylococcus species identified will be subjected to sensitivity testing using the Gram Positive antibiotic panel available at Loma Linda, with the addition of ciprofloxacin.

Conditions

  • Bacterial Resistance

Interventions

DRUG

Ciprofloxacin

Use of topical ciprofloxacin 4x daily for 3 days after intravitreal injection using standard aseptic techniques with Povidone-Iodine is a common practice intervention in the United States, and is thought by some to reduce the risk of post-injection endophthalmitis.

DRUG

Standard Aseptic Technique

Patients in this group will have received Povidone-Iodine Only following injections of anti-VEGF agents at least 3 times in the last 6 months.
