Figure 3. Morphological assessment of sensory retina in murine IOL-implanted eyes and control eyes without surgery. Apoptotic photoreceptors and ONL thickness after IOL implantation were assessed under dim light conditions (5 LUX, 12 h on/off). A: (Upper) Representative images of TUNEL staining for retinal sections 1 mm superior to the optic nerve head at postoperative day 3. (Lower) Merged images. Nuclei were counterstained with Hoechst 33258. Bar=50 µm. B: Quantification of TUNEL-positive cells in the ONL of each section, including the optic nerve head. Values are mean ±SD (n=6 in each group). C: Representative images of hematoxylin and eosin staining for retinal sections 1 mm superior to the optic nerve head at postoperative day 7. Bar represents 50 µm. D: ONL thickness of control or IOL-implanted eyes. Values are mean ±SD (n=5 to 6 in each group).
