General Binocular Vision Dysfunction |
|
This document is provided by the College of Optometrists in vision development.
Definition:
Binocular vision is the ability to align both eyes accurately on an object and combine the visual images from each eye into a single, in-depth perception. A binocular vision dysfunction is a sensorimotor anomaly characterized by the inability to efficiently, accurately and comfortably sustain eye teaming.
Signs and Symptoms:
The signs and symptoms associated with general binocular vision dysfunction may include, but are not limited to, the following:
- Transient blurred vision
- Headaches
- Transpositions when copying from one source document
- Inaccurate/inconsistent visual attention/concentration to another and/or awareness
- Diminished accuracy
- Distractibility while performing visually demanding tasks
- Abnormal postural adaptation/abnormal working distance
- Difficulty sustaining near visual function
- Inconsistent work production
- General fatigue
- Reduced efficiency and productivity
- Dizziness/vertigo; especially during or after sustained visually demanding tasks
- Diminished performance with time on task
- Light sensitivity
- Avoidance of visually demanding tasks
- Double vision
- Motion sickness
- Inaccurate/inconsistent depth judgement
- Incoordination/clumsiness
- Spatial disorientation
- Inaccurate eye-hand coordination
- General eye/visual discomfort
- Illusory movement
- Pain in or around the eyes
- Occupational/vocational limitations
Therapeutic Management Considerations:
The doctor of optometry determines appropriate diagnostic and therapeutic modalities and frequency of evaluation and follow-up, based upon the urgency and nature of the patient's conditions and unique needs.
Prescribed Treatment Regimen:
The goal of the prescribed treatment is to address the underlying condition and alleviate the presenting signs and symptoms. Most general binocular dysfunctions require optometric vision therapy/orthoptics to develop accurate and effective eye teaming. This condition rarely resolves when left untreated. Treatment duration will depend upon the particular patient's condition and associated circumstances. At the conclusion of the active treatment regimen, periodic follow-up evaluation is required. Therapeutic lenses may be prescribed during or at the conclusion of active vision therapy to assist in the maintenance of long-term stability.
