To determine the diagnostic accuracy of non-contact screening methods for identifying eyes with a narrow angle.
- To asssess and compare the accuracy of index non-contact screening tests for identifying eyes with a narrow angle
- 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)
- To explore potential causes of heterogeneity in diagnostic performance
This is a protocol.
