To the families, patients, and friends of A-Ha Vision,
Recently the provincial government lifted many of the mask mandates. Until further notice, we are continuing to require everyone entering our clinic to wear a mask at this time.
Please continue to bring your mask with you to all appointments. We apologize for any confusion this may have caused and we will continue to provide updates with your safety in mind.

Nystagmus and Vision Therapy

Nystagmus is an eye condition characterized by rapid, uncontrolled eye movements from side to side, up and down, or in circles. This condition can begin in infancy or develop later in life.

People with nystagmus tend to have problems with depth perception, struggle to identify moving objects or people and experience difficulties with balance and night vision. Their head might tilt due to a ‘null point’, this is a head position where the eye movements are reduced, so tilting the head allows more comfortable vision.

Nystagmus is caused by the brain’s inability to control eye movements and may be a symptom of other eye conditions (such as severe myopia, astigmatism and congenital cataracts) or medical problems (such as brain abnormalities, inner-ear inflammation, central-nervous-system diseases, medication side effects and albinism). Eyesight may vary, depending at what age nystagmus began. Adults may also exhibit signs of nystagmus due to multiple sclerosis or after experiencing a TIA (transient ischemic attack) or stroke.

Diagnosing nystagmus starts with an in-depth eye examination to evaluate the eyes’ ability to focus, move vertically and horizontally, work as a team and shift focus from object to object. Eyeglasses or contact lenses do not fully correct the condition, but at least being able to see more clearly may alleviate some of the symptoms. Because nystagmus is frequently related to other medical issues, patients are often referred to a variety of health care providers, including general practitioners, neurologists, or otorhinolaryngologists (ENTs).

Nystagmus and Vision Therapy

Vision therapy can help many patients with nystagmus. Vision Therapy is a customized program of visual exercises taught in our office and continued by the patient at home. Vision therapy trains the eyes to work together and master the necessary visual skills – including both eyes moving and working together to track shifting objects, whether far away, closeby, or on the periphery of the visual field.

For example, vision therapy can train the eyes to move together across a page to fixate on one word and then another. Doing so can make reading a more comfortable activity and boost reading comprehension.

Vision therapy can help some patients with nystagmus to reduce or slow their eye movements, improve focus, enable eye contact with another person and reduce fatigue while reading. Some nystagmus patients benefit from vision therapy which also includes prism, multifocal or bifocal lenses.

Our practice serves patients from Oakville, Burlington, Halton, and Mississauga, Ontario and surrounding communities.
