2007 JUL 16 -- Investigators publish new data in the report "Axonal loss and neuroprotection in optic neuropathies." According to recent research from Canada, "Most optic neuropathies do not have effective treatments. Examples are ischemic optic neuropathy, Leber hereditary optic neuropathy, optic neuritis, and traumatic optic neuropathy."

"In some cases, the pathophysiology of the optic nerve injury is not fully understood. For example, while the demyelinative aspects of optic neuritis have been studied, the mechanism by which the axonal loss occurs is less apparent. In other cases, although the pathophysiology of the optic neuropathy may be understood, there is difficulty treating the disease, for example, with traumatic optic neuropathy. In response to this therapeutic dearth, the concept of neuroprotection has arisen. Neuroprotection is a therapeutic paradigm for preventing death of neurons from injury and maintaining function. In optic neuropathies, the corresponding neuron is the retinal ganglion cell. These cells are unable to divide, and optic neuropathies irrevocably result in their death; therefore, the primary target of neuroprotection are retinal ganglion cells and their axons," wrote L.A Levin and colleagues, University of Montreal, Department of Ophthalmology.

The researchers concluded: "This review emphasizes that most optic neuropathies are axonal and thus good targets for neuroprotection."

Levin and colleagues published their study in Canadian Journal of Ophthalmology Journal Canadien D'ophtalmologie (Axonal loss and neuroprotection in optic neuropathies. Canadian Journal of Ophthalmology Journal Canadien D'ophtalmologie, 2007;42(3):403-8).
