What is vision apraxia?

Ocular motor apraxia (OMA) is a neurological disorder that causes problems with voluntary horizontal eye movement. Children with this condition have difficulty moving their eyes in a desired direction. In other words, their saccades (the quick, simultaneous movement of both eyes in the same direction) are abnormal.

What is apraxia of gaze?

Purpose: Gaze apraxia is difficulty in initiating and executing saccades, evident as abnormally long latencies and/or subnormal saccade amplitude. The purpose of the current study was to determine the prevalence and severity of gaze apraxia in children with different severities of cerebral palsy (CP).

What is ocular motor deficits?

Oculomotor Dysfunction (OMD) is also known as Ocular Motility Dysfunction and is characterized by a deficiency in one or more of the following visual skills: Fixation: the ability to “hold” the eyes steady without moving off the target.

What is ocular motor control?

Normal visual perception requires the proper functioning of ocular motor systems that control the position and movement of the eyes to focus the image of the object-of-interest (i.e., the visual target) on corresponding areas of the retinas of the two eyes.

Is ocular motor apraxia rare?

Cogan type ocular motor apraxia is a rare congenital disorder characterized by a defect in side-to-side (horizontal) eye movements. The eyes do not move properly in response to stimuli or voluntarily.

What causes ocular apraxia?

Causes. A person may be born with the parts of the brain for eye movement control not working, or may manifest poor eye movement control in childhood. If any part of the brain that controls eye movement becomes damaged, then OMA may develop.

Is ocular motor apraxia genetic?

Cogan type ocular motor apraxia is a genetic condition for which the inheritance pattern has not been well established. It is not clear if it is inherited as an autosomal recessive genetic trait or an autosomal dominant genetic trait.

Can ocular motor dysfunction be cured?

Your eye muscles are just like other muscles in your body; exercising them can help them perform better. As a result, vision therapy is one of the best treatments for ocular motor dysfunction. Vision therapy allows you to practice new skills to strengthen eye muscles’ ability to work together effectively.

What are ocular motor skills?

Ocular Motor Skills: There are three basic types of eye movements: Fixations: ability to hold eyes steady without moving off target. Saccades: the ability of our eyes to make accurate jumps as we change targets. Pursuits: the ability of our eyes to follow a moving targets.

Is ocular motor apraxia progressive?

Cogan type ocular motor apraxia is not progressive and many affected individuals eventually learn to compensate for the disorder by overshooting the eyes instead of jerking the head. The number and severity of symptoms varies widely among affected individuals.

What is ocular motor apraxia?

Ocular motor apraxia (OMA) is the absence of, or a defect in, the control of voluntary, purposeful eye movement. Children with this condition have difficulty moving their eyes in a desired direction.

What is Cogan type ocular motor apraxia?

Cogan type ocular motor apraxia is a rare congenital disorder characterized by a defect in side-to-side (horizontal) eye movements. The eyes do not move properly in response to stimuli or voluntarily.

What are the symptoms of apraxia?

The main symptom of apraxia is an inability to carry out simple movements, even though a person with apraxia has full use of their body and understands commands to move. People with apraxia may find it difficult to control or coordinate movements voluntarily.

What is the difference between buccofacial and oculomotor apraxia?

People with buccofacial apraxia, or facial-oral apraxia, are unable to make movements with the face and lips on command. People with constructional apraxia are unable to copy, draw, or construct basic diagrams or figures. Oculomotor apraxia affects the eyes.
