Visual Rehabilitation Training Of Abnormal Ocular Functional Movement

Eye functional motor visual rehabilitation training includes eye fixation visual rehabilitation training, eye scanning motor visual rehabilitation training and eye following motor visual rehabilitation training. The input part of the visual perception system is the output part of the visual perception system. Good functional eye movement reflects the good operation of sensory and perceptual system, such as accurate and lasting fixation; However, poor functional eye movement, such as nystagmus and unstable fixation, often has problems such as low vision.

Some principles of eye functional motor vision rehabilitation training:

1. In training, first emphasize accuracy, then speed.

2. For rapid saccade exercise, first rehabilitation training, large saccade exercise, and then small saccade exercise. For the smooth tracking movement, the order of rehabilitation training is just the opposite, from the small saccade movement to the large direction.

3. First, the functional motor vision rehabilitation training of monocular was carried out until the ability of both eyes was equal. Once the monocular eye functional movement is accurate, fast and equal, the binocular eye functional visual rehabilitation training can be started.

4. The head movement should be limited in the smooth tracking and rapid scanning visual rehabilitation training.

5. Gradually increase the complexity of visual rehabilitation training and develop more automatic smooth tracking and rapid scanning.

1. Eye fixation visual rehabilitation training

Eye fixation visual rehabilitation training can help patients quickly and accurately locate the space, and improve the ability of patients to quickly, accurately and effectively transfer from one fixation target to another.

2. Eye saccade motor vision rehabilitation training

The saccade reflex can be improved through monocular fixation visual rehabilitation training. The saccade visual rehabilitation training enables patients to quickly and accurately transfer from one place to another. This training can improve the basic skills of reading. In order to effectively improve human saccade motor skills, it is best to use conscious feature markers, such as words, graphics or letters.

3. Eye following visual rehabilitation training

Eye following motor vision rehabilitation training is a direct stimulation transferred from one fixation point to another to train eye following motor skills. The following movement of eyes requires the patient to coordinate the movement of both eyes smoothly, so that the retinal image can clearly fall in the fovea of macula. This ability can be gradually improved through visual rehabilitation training. Patients with insufficient eye following motor function often have perceptual abnormalities, fusion problems and reading difficulties.
