Rapid quantification of oculomotor deficits

We’re looking for people with and without strabismus, colloquially called a “lazy eye” or “childhood squint”, to try out some new computer-based tests that we’ve developed.

What's involved?

You will be asked to attend two sessions 6-8 weeks apart at the University of Auckland Grafton Campus. The first session will take 1-2 hours, the second visit will take about 45 minutes to an hour. If you have not had a full eye test in the last 12 months, we will perform some extra clinical checks at the first visit to confirm that you are eligible.

During each visit you’ll be asked to wear 3D glasses and look at a computer screen. We will be monitoring where your eyes are looking with an eye tracker, and we will sometimes ask you to describe what you see. You will receive a $20 petrol voucher for each visit.

Eligibility criteria

We are looking for children (6-15 years) and adults (16 -70 years) with and without strabismus (an eye-turn, “squint”, or “lazy eye”). We are also looking for adults (16-70 years) with strabismus who are planning to have eye muscle surgery to correct their strabismus.

If you have strabismus you are eligible to take part if:

  • You have a constant eye-turn which started when you were younger than 6 years old.
  • Your eye-turn was not caused by head trauma, direct injury to the eyes, or neurological diseases.
  • You have not had eye muscle surgery in the last 3 months (although you may have had surgery in the past).
  • You have not had any other major eye injuries, diseases, or surgeries – although corneal laser corrective surgery is okay.

If you would like to take part as a control participant, then you must not have any eye turns, and no previous history of any eye surgery or other lazy eye treatment.
