Purpose: To evaluate the in vivo corneal endothelial changes after intravitreal bevacizumab (Avastin®; Genentech Inc., San Francisco, California, USA) injection.
Methods: A total of 30 eyes of 28 patients who received intravitreal bevacizumab injections were included in the present study. Before injection and one and three months after injection, specular microscopy was performed to analyze the corneal endothelial cell changes. In order to compare the differences in the changes of corneal endothelial cells, the eyes were divided into two groups, a single injection group and a multiple injection group.
Results: The mean endothelial cell count decreased from 2,497.4 ± 427.8 at baseline to 2,421.2 ± 430.5 at one month and to 2,362.7 ± 366.2 at three months after the injection in all patients. However, the change in endothelial cell count was not statistically significant. In addition, the postoperative change in endothelial cell count was more prominent in the multiple injection group than in the single injection group, although the difference was again not significant. No significant changes in preoperative or postoperative coefficients of variation for cell area or hexagonalities were observed in either patient group or within each group.
Conclusions: There was no significant change in corneal endothelial cells after intravitreal bevacizumab injection. In addition, there was no significant difference in the changes in corneal endothelial cells according to the number of bevacizumab injections
