The Amsler Grid is most useful for assessing foveal or parafoveal dysfunction. It helps identify visual distortions (metamorphopsia) within the central 20° of the visual field caused by the physical
distortion of the retinal surface. The test also detects a central scotoma caused by optic nerve or macular disease. Amsler Grid test distance is 28-30 cm (11 to 11.8 inches). Pre-requisite is determination of adequate acuity. Make sure that the Amsler Grid is evenly lighted. Avoid artificial mydriasis or ophthalmoscopy immediately prior to presentation of the Grids. Test monocularly
with the patient wearing any near correction. Discourage the use of progressive lenses. It is recommended that the examiner is positioned opposite the patient so that the patient’s eye movements
can be monitored continuously. It may be helpful to warn the patient that this test takes some time and needs careful attention.
