OPTIC ATROPHY

WHAT IS OPTIC ATROPHY?

Optic Atrophy is the result of degeneration or damage to the optic nerve. The optic nerve transports visual information from the eye, to an area of the brain where it is processed. Optic atrophy may be inherited or may result from brain injury or conditions such as brain trauma, inflammation, degenerative disorders, haemorrhage or tumour. Reference: www.visionaustralia.org

The optic nerve carries electrical impulses from the eye to the brain, which converts the impulses into the things that you see.

Hereditary Optic Neuropathies include Dominant Optic Atrophy and Leber Hereditary Optic Neuropathy, which are both mitochondrial cytopathies. These disorders typically manifest in childhood or adolescence with bilateral, symmetric central vision loss. Optic nerve damage is usually permanent and in some cases progressive.

SYMPTOMS

The symptoms described here may not necessarily mean that you have optic nerve atrophy. However, if you experience one or more of these symptoms, contact your eye doctor for a complete exam.  Reference: www.naturaleyecare.com

  • Blurred vision
  • Decrease in visual function such as a decrease in sharpness and clarity of vision (visual acuity) or decreases in side (peripheral) vision. Color vision and contrast sensitivity can also be affected.
  • Poor constriction of the pupil in light
  • Decreased brightness in one eyerelative to the other
  • Change in the optic disc

 

CAUSES

Many diseases and disorders can lead to optic atrophy or damage to the optic nerve. Optic Atrophy can occur in cases where the optic nerve did not develop properly. it may also result from inflammation of the optic nerve or from glaucoma when the pressure inside the eye remains too high. in unusual cases, poisons, vitamin deficiencies, or tumors may be responsible. Most commonly, optic atrophy simply occurs without a known or proven cause. Reference: www.kellogg.umich.edu

 

 

TREATMENT

Unfortunately, there is no effective treatment for optic atrophy. Once the nerve fibers in the optic nerve are lost they never heal or grow back. Therefore, the best defense for optic nerve atrophy is an early diagnosis because if the cause can be found and corrected, further damage can be prevented. Reference: www.naturaleyecare.com
