Asteroid: Binocular Vision Testing Device for Children

We have developed a fun, game-based stereoacuity test.

The Challenge

Problems of binocular visual control are the most common visual disorder in children in the developed world. It is essential that these visual problems are diagnosed early in childhood. This means that therapy can minimise the likelihood of sight loss due to amblyopia, also known as lazy eye.

Current stereovision tests utilise books or plates. They only display a limited number of pre-set disparities. Stereoacuity estimates are based on just a few responses from the patient. The technique is also difficult to use in young children. The tests may need to be carried out at a set distance or whilst wearing glasses. The tests are also not engaging. Consequently obtaining an accurate estimate of stereoacuity is difficult.

The Solution

We have developed a fun, game-based stereoacuity test. It is hosted on a 3D tablet. Stereoacuity is measured as the child plays an interactive game. The viewing distance is automatically measured in real time.

A large validation study has been carried out in 1000 children aged 2 to 9 years old. It has demonstrated the acceptability of the test.

The Opportunity

We are interested in out-licensing the technology and/or identifying collaborative partners.
