Figure 7. Transmission electron microscopic changes. A: Control, B: Selenite induced, C: Selenite + FVN treated. Lenses were fixed in 2.5% glutaraldehyde and 2% paraformaldehyde for 12–18 h. Samples were processed, sectioned, stained and examined under a Hitachi H-600 Transmission electron microscope. Magnification – 8,400×. Arrows indicates enlarged, irregularly shaped fibers with opaque material.
