The equipment available to professionals working in the eye care sector continues to develop rapidly, with both steady improvements to existing types of diagnostic equipment and the introduction of new equipment. Research into the way optometric equipment is being used and the impact these uses are having on the provision of eye care is important to ensure that these developments continue to enhance care, rather than introduce confounding factors or new complications.

The project was funded through the College's Postgraduate Scholarship programme and was undertaken by City University London.

The primary objective of this project was to identify whether modern imaging and vision function-testing technologies, alone or in combination, can be used to improve case detection of eye disease in a population of patients attending community optometric practices.

The project also had the following secondary objectives:

  • defining the optimal test result criteria and test combination(s) required to achieve a cost-effective balance of true-positive and false-positive referrals from primary care
  • surveying the equipment currently in use in optometric practice for the measurement of visual function, refractive status and the determination of ocular health
  • determining the barriers and enablers to the adoption of new technology in optometric practice and to illicit views on the impact of this technology on patient care.

Guide to methods of measuring the anterior chamber angle

The project also produced a three-part guide to methods of measuring the anterior chamber angle, published in the College's CPD journal, Optometry in Practice. The three parts are available to College-members at the below links (please note, you will need to log-in):
