To describe the intravitreal injection technique practice patterns of retinal specialists in the United States from October 27, 2008 to January 10, 2009.
226 retinal specialists, with both academic and private practice affiliations, were contacted by email to complete a 10-question online survey.
75 retinal specialists (33%) responded to the survey. Most respondents measure the site of intravitreal injection from the limbus (72%), check the optic nerve for perfusion post-injection (52%), and prescribe post-injection antibiotics (87%). Most do not, however, anteriorize the conjunctiva before injection (16%), measure post-injection intraocular pressure within thirty minutes of the procedure (48%), or prescribe pre-injection prophylactic topical antibiotics (15%). A majority of retinal specialists use a 31-gauge needle for the injection of ranibizumab or bevacizumab (83%); however specialists commonly use either a 27- or 30-gauge needle for the injection of triamcinolone acetonide (51% and 44% respectively).
Retinal specialists in the United States participate in a range of techniques for the care before, during, and after intravitreal injections.
