Optic nerve diseases may damage one or both eyes and have an effect on your vision. About a million tiny nerve fibres make up the optic nerve, which transmits pictures from the eye to the brain. The brain will cease receiving visual information in a timely manner when the nerve fibres are destroyed, resulting in impaired vision. Optic nerve atrophy is sometimes referred to as optic neuropathy and optic atrophy.
The retina contains tiny photo receptor cells that detect light and send electrical impulses to the optic nerve. This nerve sends impulses from each will to the brain, where visual information is processed and we are able to see. When an optic nerve or its route to the brain is damaged, visual loss occurs. Different kinds of vision loss result from injury to the eye or the visual pathway, depending on where the damage occurs.
Symptoms of Optic Nerve Atrophy include a loss of visual sharpness, difficulties with peripheral vision, a sudden or abrupt loss of vision, abnormal colour vision, changes in the optic disc, and involuntary eye movement.
Causes of Optic Nerve Disorders
- Acquired factors such as illness or trauma
- Developmental variables such as genetics or improper growth
- Hereditary, Genetic, or Developmental
- Anomalies of the Optic Nerve
Although the method of inheritance for Leber’s Hereditary Optic Neuropathy is unknown, it is thought to be X-linked. As a result, it affects men in their 20s and 30s more often than it does women. Optic nerve hypoplasia (ONH) is an underdeveloped optic nerve caused by congenital optic atrophy.
