Chapter 7 – Diagnosis of glaucoma<br />
Evidence Statement<br />
• Expert/consensus opinion suggests that visual field testing is invaluable to diagnose glaucoma.<br />
Point of note<br />
A consistent approach to testing visual function at diagnosis, monitoring and follow-up may facilitate<br />
assessment of progression across professional settings. Health care providers are advised to utilise<br />
equipment that allows comparisons with normal visual fields, and has demonstrated reproducibility<br />
to facilitate comparisons with measures taken over time. Health care providers need to interpret<br />
product claims with caution when choosing their equipment.<br />
Evidence Statement<br />
• Expert/consensus opinion suggests that advancing age, visual acuity, patient capability, concurrent ocular<br />
conditions, oculo-facial anatomy and spectacle scotomata all impact upon the results and interpretation<br />
of visual field testing.<br />
Using visual fields to grade glaucoma<br />
Burr et al (2007) describes a continuum of glaucoma severity as:<br />
• No glaucomatous impairment: Under observation as a glaucoma suspect, however not on<br />
medication, and no glaucoma visual field defect in either eye.<br />
• Mild glaucoma: On treatment, no binocular visual field loss, unilateral glaucoma visual field defect.<br />
• Moderate glaucoma: Up to five missed points (
