Figure 7. Scanning electron microscopy of rabbit eyes treated with iHA-VMA and VMA. A, C: Control (contralateral) eyes showing dense vitreous cortical fibers, suggesting no induction of posterior vitreous detachment (PVD). B, D: Inner retinal surface of representative animals injected with inhibitor of hyaluronic acid-Vibrio mimicus collagenase that remains active (iHA-VMA) or VMA, showing the retinal surface devoid of any collagen fibers, suggestive of induction of complete PVD. Scale bar = 1 µm; 10,000X magnification.
