CASPAR’S CASTLE – a visual field analyser developed specifically for children

Background

Perimetry testing is of vital importance for the early detection and monitoring of neurological diseases and glaucoma. These tests are commonly performed in the adult population but are equally as important in children for the detection serious underlying medical conditions. Using machines designed for adults or clinical examination can result in inaccuracies and defects being missed. Children, particularly those under 6, or individuals with learning difficulties struggle to stay focused and don’t understand the test which leads to inconsistent results and problems with diagnosis or monitoring.

A team from the University of Manchester have proposed a solution to this problem using gamification to make the test fun, easy and engaging. Essentially the test is performed as part of a game where the level of visual field is assessed without the child needing to be aware that their level of visual field is the output.

The technology

The UoM has turned perimetry testing into a fun game that enables children to remain engaged and enjoy the testing experience. Caspar’s Castle only requires the proprietary software, a laptop, LCD screen and external buttons

Key benefits

  • The system had proven usability, validity and reliability.
  • Suitable for 4 year olds and upwards.
  • Substantially more children were happy to be retested using Casper’s Castle compared to other tests.
  • The software solution can be integrated with existing systems or be stand alone.
  • Minimal training for operator.

Applications

Children’s perimetry testing.
