Neurological Disorders
Neurological is defined as having to do with the nervous system, including the brain, spinal cord, nerves and muscles. Neurological disorders can affect your eyes and your vision in many ways. Some of these disorders include:
Blepharospasm – an involuntary and uncontrolled blinking of your eyelids that is believed to originate in the basal ganglia, the portion of the lower brain responsible for coordinated movements.
Double vision – caused by a disruption of the blood flow to the cranial nerves at the base of your brain. These nerves send signals to the six muscles that control the movement of your eyes.
Ischemic optic neuropathy – a sudden loss of vision caused by a disruption of blood flow from the ciliary arteries to the optic nerve, resulting in damage to all or part of the optic nerve. A healthy optic nerve is essential to transmit images from the retina to your brain.
A stroke or “brain attack” – a disruption to the blood flow to the brain which damages brain cells that can cause permanent or temporary impairment of your vision.
Temporal arteritis – a disruption of blood flow to the head and eyes, that can also result in sudden vision loss.
