To examine the incidence of blood splatter during intravitreal injections.
One vitreoretinal specialist performed 100 consecutive intravitreal injections. After patients' eyes received anesthetic via pledgets soaked in 4% lidocaine and cleaned with betadine swabs, the specialist wore a plastic eyeshield . Once the intravitreal injection was performed, the eyeshield was removed. A new eyeshield was used for each injection. The shields were subsequently dried and stored. Each shield was sprayed with luminol a bioluminescence blood detection system. A questionnaire was provided after each injection for the vitreoretinal specialist asking if there was any intraprocedural blood splatter. One eyeshield was also placed as a control in the procedure room for 1 hour while injections were not being performed.
Of the one hundred shields, seven were found to have blood splatter. On post-procedure questionnaire, the vitreoretinal specialist denied any knowledge of blood splatter. The control eyeshield was not found to have blood splatter.
Intraprocedureal blood splatter during intravitreal injections risks transconjunctival transmission of human immunodeficiency virus and viral hepatitis. This study is the first of its kind to document a 7% risk of blood splatter during intravitreal injections.
