A neurological exam tests the twelve cranial nerves by subtly dissociating their functions. Shining a small flashlight into one eye, for example, can distinguish between damage to CN II (the optic nerve) and damage to CN III (the oculomotor nerve).
What neurological disorders cause eye problems?
- Optic Neuropathies. Damage to the optic nerves can cause pain and vision problems, most commonly in just one eye. …
- Optic Neuritis. …
- Giant Cell (Temporal) Arteritis. …
- Chiasm Disorders.
What is a neurological eye exam?
The neuro exam allows you to assess structures neighboring those that are important to vision and can help determine the level of urgency for a patient's ocular findings such as visual field defects, cranial neuropathies, double vision, optic neuropathy, ptosis, pupillary abnormalities and loss of vision.
What can a neurologist see in eyes?
A neuro-ophthalmologist can diagnose and treat neurological and systemic diseases that affect your sight and the movement of your eyes. The tests they may give you include electroretinography, optical coherence tomography, and multi-focal EGRs.
Can a neurologist diagnose eye problems?
Ophthalmologists treat eye and visual problems, and neurologists deal with issues of the brain. A neuro-ophthalmologist is in the middle, handling brain issues that affect vision. Neuro-ophthalmologists treat many vision disorders in addition to those associated with MS.
What are signs of optic nerve damage?
- Pain. Most people who develop optic neuritis have eye pain that's worsened by eye movement. …
- Vision loss in one eye. Most people have at least some temporary reduction in vision, but the extent of loss varies. …
- Visual field loss. …
- Loss of color vision. …
- Flashing lights.
What health conditions can cause eye problems?
- Refractive Errors.
- Age-Related Macular Degeneration.
- Diabetic Retinopathy.
What does a full neurological exam consist of?
The neurologic examination is typically divided into eight components: mental status; skull, spine and meninges; cranial nerves; motor examination; sensory examination; coordination; reflexes; and gait and station. The mental status is an extremely important part of the neurologic examination that is often overlooked.
What do they look for in a neurological exam?
A neurological examination assesses motor and sensory skills, hearing and speech, vision, coordination, and balance. It may also test mental status, mood, and behavior. The examination uses tools such as a tuning fork, flashlight, reflex hammer, and a tool for examining the eye.
Can eye problems cause loss of balance?
Vision problems can make it challenging to maintain proper balance. When someone has troubled vision and the eye muscles work harder to compensate for the decreased visual clarity, eyestrain, headaches, and balance disorders can occur.
Can an MRI detect eye problems?
MRI can provide better information about the eye in the context of the orbit than any other ocular imaging device. This allows detection of the etiology of ocular abnormalities related to primary orbital pathologies (2,4–7).
What causes nerve damage in the eyes?
Optic nerve damage case be caused by eye diseases like glaucoma, poor blood flow (ischemic optic neuropathy), shock or trauma, toxins such as lead or carbon monoxide, radiation, or diseases of the central nervous system.
Can spine problems cause vision problems?
A pinched or damaged nerve in your spine may lead to blurred vision or headaches, loss of hearing, slurred speech, and bowel and bladder problems, to name a few.
Can nerve damage affect eyes?
Damage to an optic nerve can cause vision loss. The type of vision loss and how severe it is depends on where the damage occurs. It may affect one or both eyes.
What part of your brain affects vision?
The occipital lobe is the back part of the brain that is involved with vision. Temporal lobe.
Can brain problems cause eye problems?
Although eye problems typically stem from conditions unrelated to brain tumors—such as astigmatism, cataracts, detached retina and age-related degeneration—they can sometimes be caused by tumors within the brain. Brain tumors can lead to vision problems such as: Blurred vision. Double vision.
