Vision post Brain Injury Toowoomba | Vision post Brain Injury Highfields
40 to 50% of the brain is taken up with the function of vision with many parts of the brain tasked with vision processing. Each part has to be connected to other parts of the brain. All these connections make vision more prone to damage. If there is damage to the brain in a certain area, or several areas, there is a high chance that vision will be affected.
Tests of eye movement and control are becoming important tools in assessing concussion in players of contact sports. The connection between vision and the brain’s injury is an important indicator of damage.
Brain Injury Visual Problem Symptoms
After a brain injury a patient may experience blurred vision, increased light and glare sensitivity, reading difficulty as the words appear to move, poor balance, bumping into people or objects, comprehension difficulty, attention and concentration difficulty, memory difficulty, double vision, aching of the eyes, headaches, and reduction in the field of vision (loosing segments of vision).
Brain Injury Visual Problem Causes
Brain injury can be caused by many events including
- stroke – where part of the brain is damaged by a haemorrhage or blockage in a blood vessel of the brain
- lack of oxygen – for instance, after drowning or heart attack
- head injury – after a car accident, fall or concussion from a sporting injury
- infection – such as meningitis or cytomegalovirus
- disease – for instance, brain tumours and multiple sclerosis
Visual Rehabilitation post Brain Injury
Visual rehabilitation may be possible in some instances.
Managing the best outcomes in these cases requires a different approach and relies on the experience of our optometrists, combined with specialised lenses and/or retraining of the functions that have been lost.
Careful assessment of the damaged functions is quite different to a standard eye test.
As each patient’s symptoms and causes are different, each case will be treated differently. Please make an appointment with one of our optometrists to discuss your situation.
