Optic nerve atrophy is injury to the optic nerve. The optic nerve takes away the images of what we see by coding through electrical impulses from the eye to the brain. It consists of a network of nerve fibers carrying the image information from the retina to the brain. Any damage to these nerve fibers, affects the brain and transport of all the vision information and our sight becomes unclear.
Optic nerve atrophy can be defined as injury to the optic nerve consequential to relapse or destruction of the optic nerve. Optic atrophy can also be called optic nerve head pallor for instance of the pale form of the optic nerve head present at the backside of the eye.
Optic atrophy is the outcome of harm to the optic nerve due to several factors. The Optic atrophy can cause problems with vision.
The symptoms are generalized to eye diseases and you may consult the ophthalmologist. Usually the symptoms associated with Optic atrophy are related to modification in vision. Blurred vision, difficulty to see on the peripheral side, difficulty in vision of colors, decline in sharpness of vision, reaction of the pupil to light reduces, decrease in the brightness in either one or both the eyes, alteration in optical disk are some symptoms observed in the patients suffering from Optical atrophy.
Numerous diseases can go ahead to optic atrophy or harm to one or both optic nerves. Optic atrophy can happen in people in whom the optic nerves did not build up properly. It might as well be consequence of the inflammation of the optic nerve or glaucoma when the pressure within the eye is elevated. In some cases, toxins, vitamin deficiencies, or tumors are to blame. The majority times, optic atrophy merely occurs exclusive of an identified or confirmed cause.
Many unrelated causes of optic atrophy are found. The popular cause is reduced blood flow, called ischemic optic neuropathy, which often affects old people. The optic nerve can furthermore be injured by shock, emission, and trauma.
Additionally, the condition can be caused by some diseases of the brain and central nervous system, for instance brain tumor, cranial arteritis, multiple sclerosis, strokes. Several rare forms of hereditary optic nerve atrophy are present that create concern in children and teenagers.
Ophthalmologist can inspect by looking through the pupil of the eye with a particular instrument called an ophthalmoscope. This gives the ophthalmologist to look for an optic nerve. This tiny disc might appear pale or white, demonstrating loss of nerve fibers, if the Optic atrophy disorder is present. Any of the symptoms mentioned above are notified to the ophthalmologist, can further be useful for further investigation.
Regrettably, there is no helpful treatment for optic atrophy. Once the nerve fibers in the optic nerve are injured or break they cannot be grown or healed. Consequently, the most excellent protection is to diagnosis the disorder to prevent it from further damage and loss of vision.
