Figure 2. Photomicrographs of the eye and associated structures from E18.5 mice treated with vehicle-only, TNP-470, or AS_4.5. Photomicrographs of representative E18.5 murine eyes stained with toluidine blue are as follows: vehicle-only treated (A), TNP-470-treated eyes (B), and AS_4.5-treated eyes (C). The ocular cross-sectional area is clearly smaller in the TNP-470- and AS_4.5-treated groups when compared with controls (compare with Figure 1). In the images, the scale bar=500 μm.
