Many people haven’t heard of Binocular Vision Dysfunction or BVD for short. Nevertheless, it is a surprisingly common visual condition that can cause patients to experience a range of unpleasant symptoms. The key characteristic of BVD is eyes that are slightly out of misalignment, which means that they don’t work together as well as they could. Since the line of sight from one eye is a little different from the line of sight from the other, the muscles of the eye have to work much harder than they should to correct the alignment and achieve a single line of focus.
When you are looking around and taking in a wide area, this issue isn’t as pronounced. However, when you are trying to concentrate on something, such as a digital device, a book or a computer screen, the extra effort that is needed by the eye muscles can become painful, resulting in the symptoms that are associated with the condition.
We are delighted to be able to offer the diagnosis and treatment of BVD here at our office in Cave Creek, AZ. In the meantime, here is what you need to know about binocular vision dysfunction.
There is a huge range of different effects associated with binocular vision dysfunction. If you are experiencing any of the following symptoms you could be suffering from BVD:
Clumsiness / poor coordination
Unsteady when walking
Poor depth perception
Headaches and facial pain
Neck and upper back/shoulder pain
Sensitivity to light
Anxiety/feeling overwhelmed when in crowds or large spaces
Fatigue when reading
Difficulty reading such as losing you places or skipping lines
You may find it easier to cover an eye to see more clearly
The severity with which your symptoms affect you can vary substantially, and while one patient may be able to manage fairly well day to day, others may find that their ability to function normally is significantly impaired.
Fortunately, there is a treatment that can eliminate the symptoms of binocular vision deficiency – micro-prism lenses. Micro prism lenses are standard eyeglass lenses that have been infused with small amounts of grinded prism. Exactly how much prism you will need in your lenses will depend on the extent of your eye misalignment. However, once the prism is infused into your usual prescription lenses, it can make it much easier for your eyes to focus on one single line of sight. Although you may notice a definite improvement of up to 50% in your vision immediately, over subsequent visits where your micro-prism lenses are perfected, the average patient will see an impressive 80% reduction in their symptoms by the end of their treatment.
NeuroVisual specialists have the necessary education, training, and experience to be able to identify and diagnose Binocular Vision Dysfunction and provide the appropriate treatment.
Before a patient can be approved for neurovisual medicine, they must first undergo a comprehensive vision assessment. This is to ensure that the issues that they are experiencing can indeed be resolved using this type of treatment. These assessments can last for between two and three hours long, and so patients are asked to ensure that they allow enough time for this assessment. This will include taking a very thorough medical history and specialized testing.
The way in which BVD is treated is through using bespoke prisms which are incorporated into your glasses or lenses. These will effectively displace the image that one eye sees so that it matches up perfectly with the other eye, counteracting the misalignment that the patient usually experiences. The exact amount of prism needed will vary between patients and will be fine-tuned over a series of appointments. Most patients can expect to see up to a 50% improvement in their symptoms right away, and at the end of fine-tuning, the average patient will have around an 80% reduction in the symptoms of BVD that they have been experiencing. This can make a tremendous difference in their quality of life.
