Many binocular vision disorders cause patients so suffer from similar symptoms. First, keep in mind that signs and symptoms are abnormalities that can indicate a potential problem, so it's always a good idea to get an evaluation by a licensed medical professional (optometrist, ophthalmologist) if you experience any of these. Signs are objective - that means it can be seen, evaluated, or tested (for example a visible eye turn). Symptoms are subjective, meaning experienced or apparent only to the patient (for example eye pain, tired eyes, etc.).
The graphic below illustrates some common binocular vision disorders encountered in an eye clinic (this is by no means an exhaustive list).
When the two eyes do not function together appropriately, a patient can present with eye issues through a variety of symptoms and signs. Symptoms of a Binocular vision dysfunction may include (but is not limited to):
Signs of a binocular vision disorder are more obvious (and maybe concerning if they are brand new!)
As you can see, the list of SIGNS easily observed that suggest a disorder of binocular vision is far less than SYMPTOMS. To further complicate the symptom/sign discussion, conditions like a history of a head or traumatic brain injury may exacerbate these symptoms.
