Frequency and Symptoms of Intravitreal Silicone Oil Droplets Following Becton Dickinson and Norm-Ject Bevacizumab Injections.

BACKGROUND AND OBJECTIVE

To determine silicone oil droplet frequency and symptomatic impact in patients injected with Norm-Ject (NJ) and/or Becton Dickinson (BD) intravitreal bevacizumab.

PATIENTS AND METHODS

This was a retrospective cohort study of 426 patients with prior bevacizumab injection(s). Symptomatic floaters questionnaire responses were compiled and statistical analysis was performed using Fisher's exact t test with 95% CI calculated via the modified Wald method.

RESULTS

Patients who received BD intravitreal bevacizumab showed more droplets (67.2%) than those who received NJ intravitreal bevacizumab (7.8%), and droplets increased with injection quantity. However, the symptomatic patients reporting new floaters were similar (NJ: 39.22%, BD: 39.47%). .
