Subconjunctival reflux and need for paracentesis after intravitreal injection of 0.1 ml bevacizumab: comparison between 27-gauge and 30-gauge needle

摘要

Purpose Intravitreal injections may lead to a significant elevation of the intraocular pressure (IOP). A paracentesis may become necessary for acute reduction of the IOP in certain cases. The purpose of this study was to determine the frequency of paracentesis performed and the grade of reflux under the conjunctiva after injection of 0.1 ml bevacizumab (1.25 mg), depending on the thickness of the needles used.
