INJECTION TECHNIQUE

Never inject if blepharitis or conjunctivitis is present; external infections should be treated intensively for several days before injecting and the patient examined at the slit lamp before injecting to verify eradication of the infection.

Never stop anticoagulants before intravitreal injections or vitrectomy; the risk of bleeding is exceptionally low, bleeding is rare and minimal, and the risk of thromboembolic events is increased. Many patients as well as their medical doctors and nurses stop anticoagulants before injections and surgery even though they were not instructed to do so, increasing thromboembolic risk, potentially creating a scenario in which an anti–vascular endothelial growth factor compound is wrongly blamed for a stroke or myocardial infarction (1).
