Figure 6. Scanning electron microscopic changes. A: Control, B: Selenite induced, C: Selenite + FVN treated. Dissected lenses were fixed in 3% glutaraldehyde in 0.1 M phosphate buffer at 4 °C. After fixation the lenses were dehydrated in graded acetone series and critical point dried. The lenses were then coated with gold and used for the SEM study under a Philips scanning electron microscope 501(B) at 50 kV. Magnification – 2,000×. Arrows indicates abnormal fiber structure and numerous spherical bodies in lens.
