What conditions cause downbeat nystagmus in all direction of gaze? The DBN cause my vision to "slip" and see stationary objects slide.
Jerk nystagmus: The four most frequent identifiable causes of downbeat nystagmus are cervico-medullary junction anomalies (Chiari malformation), cerebellar degenerations, multiple sclerosis, and vertebrobasilar infarction. Medications and alcohol are other relatively common causes. Uncommon causes include B12 deficiency and familial. An MRI should be done if you have not had one yet. Treatment is dalfampridine. ...Read more
Probably not: Nystagmus from childhood brain or eye problems, sometimes with dramatic motion, does not cause a perception of what is viewed to be moving. Acquired nystagmus from injury or toxicity can cause a perception of environmental motion. The motion is linear in most cases and will not be perceived as wavy. Wavy lines are most commonly due to macular problems which your ophthalmologist can assess. ...Read more
Maybe: Dizziness is a very ambiguous and subjective word that can mean many things. Nystagmus is an objective finding. That means, a good doc can examine a patient and determine if they have nystagmus. It means the eyes are rhythmically moving in a particular direction. The direction and speed can be useful in making a diagnosis. Not all dizziness results in nystagmus as nystagmus usually means inner ear. ...Read more

Finally, it would help if you stated why you are seeking the information. ...Read more
Complicated!: Balance is achieved by the brain coordinating eye input, inner ear input (telling brain where head is in space) and muscle input (keeping us upright). When one of the inputs is abnormal (inner ear, for example) we experience vertigo. Because the paths (eye, ear, brain) are all linked nystagmus (abnormal gaze fixation) can occur when the inner ear is affected by inflammation or infection. ...Read more

If downbeat nystagmus causes stationary objects to move up/down & back/forth and slide would this be considered oscillopsia?
Possibly: Oscillopsia is The illusion of oscillation of the visual surroundings and is associated with certain neurological processes, most commonly meningitis. Nystagmus is a physical finding on examination. A person with nystagmus from birth would not be aware of oscillopsia whereas someone with acquired nystagmus might. ...Read more
I'm curious. How common is nystagmus? Also can ritalin (methylphenidate) cause it? What's the chance of it going away if nystagmus is acquired?
Can convergence insufficiency be the cause of my daughter's nystagmus? It only presents when looking near and all her tests have came back normal.
Convergence insufficiency is a common cause of visual complaints such as the following list on a standard screening questionnaire.
* one eye drifts or aims in a different direction than the other (this can be subtle). This is significant even if it only occurs when tired or stressed.
* turns or tilts head to see
* head is frequently tilted to one side or one shoulder is noticeably higher
* squinting or closing or covering of one eye
* excessive blinking or squinting
* short attention span
* daydreaming at school/work
* poor handwriting
* poor visual/motor skills (often called "hand-eye coordination")
* problems moving in space, frequently bumps into things or drops things
While reading or doing close work:
* holds the book or object unusually close
* closes one eye or covers eye with hand
* twists or tilts head toward book or object so as to favor one eye
* frequently loses place and fatigues easily
* uses finger to read
* rubs eyes during or after short periods of reading
* reversals when reading (i.e., "was" for "saw", "on" for "no", etc.)
* reversals when writing (b for d, p for q, etc.)
* omitting small words
* confusing small words
* transposition of letters and numbers (12 for 21, etc.)
* loss of place when reading, line to line and word to word.
* child's ability to learn verbally surpasses his ability to learn visually.
Frequent complains of:
* only being able to read for short periods of time
* headaches or eyestrain
* nausea or dizziness
* motion sickness
* DOUBLE VISION!
It is not a cause of nystagmus. If your daughter has true nystagmus she should have an examination by an ophthalmologist to determine the cause. One can have both conditions but the CI does not cause nystagmus. ...Read more

Can be both: Nystagmus can be congenital or acquired. Congenital form can associate with an underlying hereditary eye disease or by itself alone. Acquired form can be from certain medications, diseases that affect the eye sight or neurologic conditions. Congenital forms occur from day one after birth, while acquired forms can happen any time during life time. Any nystagmus should be evaluated. ...Read more
