Binocular vision dsyfunction (BVD) occurs when the eyes are unable to work together efficiently, leading to issues such as double vision, dizziness, headaches, and difficulty reading. This condition is common following concussions due to the impact on the brain’s ability to coordinate eye movements.
If you experience a concussion or traumatic brain injury (TBI), there is a significant chance that it will impact your vision, potentially leading to binocular vision dysfunction (BVD).
This page provides essential information on how concussions can disrput your visual system, the symptoms to watch for, and why a specialised neuro-optometric evaluation is crucial. If you experience these symptoms, it is recommended to visit both a doctor and an optometrist for a thorough assessment.
A concussion or traumatic brain injury (TBI) disrupts normal brain function due to a blow to the head, stroke, or neurological dysfunction. Studies show that at least 50% of TBI patients experience visual dysfunctions, with some studies reporting up to 90% incidence of post-trauma visual complications.
Children often suffer concussions due to sports injuries, while in adults, the most common causes include motor vehicle accidents and falls.
Many post-concussion symptoms, including dizziness, blurred vision, and difficulty focusing, stem from BVD but are often overlooked in standard medical evaluations.
Binocular vision dysfunction can manifest in various ways after a head injury, including:
Feeling dizzy or uncomfortable when scrolling on screens or in busy environments.
Difficulty tracking moving objects, reading, or maintaining focus for extended periods.
Persistent eye strain and headaches, especially during tasks that require focus.
Trouble with depth perception, leading to difficulties in walking or standing.
Increased discomfort from sunlight, fluorescent lights, and digital screens.
Difficulty maintaining a single, clear image, often affecting reading and driving.
Struggles with estimating distances, such as catching a ball or navigating stairs.
Decreased awareness of objects appearing from the side.
Reduced blink rate, leading to dry, irritated eyes and blurred vision.
A regular eye exam may indicate that your eyes are healthy and that your vision is clear. However, post-concussion visual dysfunction, such as BVD, affects how the brain processes vision rather than the eyes themselves. This means that standard eye tests may not detect the full extent of the issue.
At Adelaide City Optometrist, we specialise in identifying and treating BVD with advanced diagnostic tools like Eye-Sync, which measures eye movement abnormalities following a concussion.
A neuro-optometric assessment evaluates complex visual processes beyond standard eye tests. This includes:
Every injury is unique, so treatment plans are customised to the individual’s needs. Paul Fotkou, alongside Christina Karapetis, provides specialised evaluations and follow up care to restore visual function post-concussion.
Recovery from binocular vision dysfunction depends on factors such as:
Most patients see improvements quickly, but full rehabilitation is a gradual process. The brain needs time to retrain and rewire itself after an injury.
If you’ve experienced a concussion and are struggling with binocular vision dysfunction, don’t ignore the symptoms. Early intervention with neuro optometric rehabilitiation can significantly improve your vision, balance, and overall quality of life.
At Adelaide City Optometrist, we use cutting-edge technology to diagnose and treat BVD following concussions. Book an eye test today and begin your path to recovery.
BVD occurs when the eyes don’t work together properly, leading to symptoms like double vision, dizziness, headaches, and difficulty concentrating.
Common symptoms include double vision, dizziness, headaches, poor concentration, eye strain, and fatigue.
BVD is diagnosed through a thorough eye exam, including tests for eye alignment and coordination. At Adelaide City Optomtrist, testing involves two appointments, each lasting one hour.
Treatment options may include prism lenses, vision therapy, and tinted lenses to improve eye alignment and reduce symptoms.
People with a history of concussions, strokes, or neurological conditions are more likely to develop BVD.
Yes, BVD is often associated with head injuries, strokes, traumatic brain injuries, and other neurological issues.
Currently, Medicare does not cover the cost of BVD testing or treatments such as prism lenses, but we offer payment options at Adelaide City Optometrist.
