This study will compare SITA-Standard and SITA-Fast tests in patients newly referred to the glaucoma screening clinic at the RD\&E hospital. In addition to standard care (SITA-Fast) each person who agrees to take part in the trial will undertake one extra visual field test (SITA-Standard). By comparing the results of the two types of visual field test the investigators aim to provide information on which of the two tests is more specific for glaucoma and which test is better tolerated by patients. The investigators anticipate that this study will generate sufficient data to support a grant application for a longitudinal study to examine the relative merits of different visual field tests in patients with glaucoma and those suspected of developing the disease.
