Gonioscopy: evaluation of the anterior chamber angle. Part II

Gonioscopy is the standard procedure for examination of the anterior chamber angle, and is an invaluable technique in primary eye care. The clinician must practise the technique and observe many angles, because enormous but often subtle variation can be seen by the experienced observer in both normal and abnormal angles. Gonioscopy is essential to master, not only for the assessment of patients' risk for angle closure following dilation, but also in the diagnosis and subsequent management of the acute and chronic glaucomas and many other anterior segment disorders.
