Reflux after intravitreal injection: an anterior segment optical coherence tomography study

Purpose: To investigate the intraocular pressure and conjunctival thickness changes following the intravitreal injection Methods: Sixty eyes of 60 patients having intravitreal injection for age-related macular degeneration, macular edema associated with diabetes, central retinal vein occlusion, and branch retinal vein occlusion were enrolled. Intraocular pressure (IOP) was measured by Tonopen-Avia (Reichert Inc., NY, USA) in sitting position and five superior-temporal conjunctival images were obtained using the Anterior Segment 5 Line Raster scanning protocol of Cirrus HD-OCT 4000 (Carl Zeiss Meditec, Dublin, CA, USA) just before the intravitreal injection. 0.05 ml bevacizumab with 27-gauge needle, 0.05 ml ranibizumab with ...
