Purpose: To evaluate the effect of intravitreal injection on the corneal endothelium according to the injected drug.
Methods: The present study included 118 eyes of 113 patients who received intravitreal injection. Before each injection and 1 month after the injection, specular microscopy was performed to evaluate the corneal endothelial changes and central corneal thickness. We classified the patients according to the injected drug (bevacizumab 21 eyes, ranibizumab 20 eyes, aflibercept 47 eyes, dexamathasone implant 30 eyes), phakic or pseudophakic eyes, single or multiple injections and analyzed them retrospectively.
Results: The mean corneal endothelial cell density was 2,693.2 ± 298.2 cells/mm2 before injection and 2,686.8 ± 288.7 cells/mm2 1 month after injection, and there was no statistically significant difference (p = 0.731). According to the kind of drug, the mean corneal endothelial cell density and central corneal thickness were not significantly different before and 1 month after injection in any of the 4 groups.
Conclusions: There were no significant changes in corneal endothelium before and 1 month after intravitreal injection of the various drugs.
