gonioscopy
Last reviewed 06/2022
- gonioscope
- mirrored contact lens (goniolens), used with slit lamp biomicroscopy, or a contact prism lens (gonioprism) which enables observation of the anterior chamber angle
- allows the examination of the anterior chamber angle using a gonioscope to observe angle structures and estimate depth of angle
- measures the angle between the anaesthetised cornea and the iris
- assesses whether the glaucoma is open or closed angle
- procedure is painless - however some patients find it difficult to tolerate and the procedure is then limited by blepharospasm
