A patient's visual acuity can be impaired by ailments such as choroidal neovascular lesions or AMD. Perimetry is used to measure a patient's sensitivity to differential light within their visual field, by displaying objects to the patient and measuring their response to them. Test objects – often just small spost of light – are projected onto a hemispherical surface. In standard static perimetry, objects of varying sizes and shapes remain fixed in position (hence static) across the visual field, but change in luminosity or size via computer control. These perimeters offer up to 80 degrees of measurement range across the hemisphere. The patients sensitivity threshold can be mapped as a traditional chart, a 3D or grayscale image, or a statistical profile. Static perimetry is often included in all-in-one visual testers, though stand-alone devices are also available.
