Comparison between rat embryonal neurosensory precursor retinal cells treated with 1.0 mg/mL dexamethasone solution (Dex-S), 1.0 mg/mL dexamethasone powder (Dex-P), or DMSO controls. Cells exposed to 1.0 mg/mL dexamethasone powder showed a significant decrease in cell viability when compared to controls, but less toxicity than cells treated with commercially available dexamethasone (P<.01).
