Hematoxylin-eosin stained horizontal sections in non-recovery anaesthesia live animal experiments.

<p>Hematoxylin-eosin stained horizontal sections through the optic nerve head and the areas nasal and temporal to the nerve head after pars plana vitrectomy using a hypersonic vitrector at 10%, 20%, 40%, or 50% ultrasound power. Vacuolization can be seen at all settings, as well as fragmentation of the nerve fibers and ganglion cell layers. The inner limiting membrane showed separation without disruption. (RE = right eye; ONH = optic nerve head; LE = left eye).
