What’s new in perimetry?




Eye care specialists that are involved with the management of glaucoma patients and individuals at risk of developing glaucoma utilize perimetry and visual field testing as diagnostic procedures to assess the functional properties of vision to determine the stage of glaucomatous damage, consider treatment options, evaluate vision impairment that the patient may not be aware of, and assess whether there may be any potential deficits in quality of life or activities of daily living. Although evaluation of the peripheral visual field has been an important part of the eye examination for glaucoma patients, recent enhancements to this procedure have improved its clinical value. This chapter will provide a review of five areas that have improved perimetry and visual field testing for clinical examination of patients with or at risk of developing glaucoma:
1. measurement of visual field sensitivity in the macula and the far periphery;
2. new test procedures that have improved the accuracy and efficiency of perimetric test procedures;
3. methods to analyze and interpret visual field test results;
4. the recommended frequency for visual field testing in glaucoma; and
5. the use of tablets and virtual reality headsets as a means of performing visual field testing with inexpensive, highly portable devices.
