WebThe optic nerve formed by the axons of RGCs also retains fiber tracts similar to that of brain neurons. Specifically, the optic nerve is covered with a myelin sheath and enclosed in three protective meninges (Figure 2B). Similar to brain axons, trauma of the optic nerve leads to retrograde and anterograde degeneration of the injured axons. WebTwenty patients had a history of ON in one eye. Compared to the non-affected eye, this eye had a lower RNFL (109 vs 115 µm, P =0.04) and a higher central retinal thickness/mean RNFL ratio (2.7 vs 2.4, P =0.04). Conclusion: Although patients with long-term MS and a previous history of ON did not have any functional loss of vision, structural ...

As the nerve fibers pass through the lamina cribrosa sclerae they lose their medullary sheaths and are continued onward through the choroid and retina as s… kerry ireland police department
