A HE staining of eyeballs of mice treated with different formulations at day 14. The white and yellow arrows represent injured RPE and inflammatory cell infiltration. The bar is 200 μm. B TUNEL immunofluorescence staining of eyeballs of mice treated with different formulations at day 14. The bar is 200 μm. The apoptosis is primarily assessed based on the presence of significant green fluorescence accumulation points, which are labeled with white arrows. The fluorescence intensity is quantified by Image J and indicated in the lower left corner of each figure
