Non-contact methods for the detection of people at risk of primary angle closure glaucoma

To determine the diagnostic accuracy of non-contact screening methods for identifying eyes with a narrow angle.

  1. To asssess and compare the accuracy of index non-contact screening tests for identifying eyes with a narrow angle
  2. To investigate the accuracy of each non-contact screening method for detecting the most severe referable condition or PACG (versus PAC, PACS or a non-occludable angle)
  3. To explore potential causes of heterogeneity in diagnostic performance

This is a protocol.
