Abstract | INTRODUCTION: METHODS: The rAION was induced in female Wistar rats. Animals were randomized into 3 groups: 1) untreated, 2) treated with 56 μg IVTA, and 3) intravitreal saline (placebo). Procedures were performed in the left eye, with the right eye serving as control. After 30 days, animals were sacrificed and eyes were assessed histologically for RGC number. RESULTS: The average number of RGC was significantly lower in rAION subgroups when compared with the control group (P < 0.001). No significant difference was seen between rAION eyes treated with IVTA, placebo, and untreated eyes (P > 0.05%). CONCLUSIONS: In this rodent model for AION, no therapeutic benefit of intravitreal steroid injection was identified.
