Optic nerve neuropathies – causative factors, methods of diagnostics, current and future possibilities of treatment

Journal of Education, Health and Sport, 2022
Introduction:  Optic neuropathies are a broad group of diseases in which the dominant disturbance is damage to the optic nerve, often irreversible. Underlying causes of neuropathy are both genetic and environmental.

Hereditary Optic Neuropathies [PDF]

Eye, 2001
The hereditary optic neuropathies comprise a group of disorders in which the cause of optic nerve dysfunction seems to be heritable as demonstrated or suggested by familial expression or genetic analysis. Clinical variability, both within and among families with the same disease, often makes recognition and classification difficult.
