PLEASE READ THIS LEAFLET CAREFULLY

It explains your test and contains important information

A doctor has requested that we perform a special visual test to assess how well your eyes are working. The examination is completely painless and will provide useful information for the doctor.

What does the test involve?

The examination involves placing small sensors on your head using a small amount of gel. The sensors detect your brain wave responses. You will be asked to look at a TV screen that has a moving checkerboard pattern on it.

Please allow approximately 1 hour for the appointment. Due to the duration of the appointment and lack of child-care facilities in our department, we request you do not bring any other child with you.

Preparation – what you need to do

  • If you use spectacles please bring them with you.
  • Please make sure your hair is clean and dry for the test. Please do not apply any hair preparations such as gel, mousse or hair spray.

After the test

At the end of the test the gel will be removed. No test results are available on completion of the test so you will be free to leave. The test results will be analysed by the Consultant Neurophysiologist who will send a report on the test results to the doctor/consultant who referred you for the test.

The appointment

Please make special note of the appointment date particularly if the appointment is some weeks away. Please let us know if the appointment coincides with another outpatient appointment or if you are unable to attend. We can reschedule your test for another time and give the present slot to another patient. This will help to reduce our waiting lists and operating costs.
