Pearls from the EGS Guidelines

Anterior chamber angle imaging cannot replace gonioscopy

Publishing date: January 2021

Pearls Manager: Andrew Tatham

Anterior chamber angle imaging devices can be useful to identify the iris configuration of a narrow angle, to assess the influence of the lens, for triage, or in eyes where the angle cannot be visualised by gonioscopy. However, anterior chamber angle imaging should not replace gonioscopy since features such as peripheral anterior synechiae, pigment, and other secondary causes of trabecular dysfunction may be missed. Gonioscopy should be performed in every patient evaluated for glaucoma.
