The Amsler Grid is a tool for identifying distortion in your visual field. It is a convenient eye test that you can use at home to monitor changes in your vision. It helps to detect many problems early, while they may still be treatable, such as retinal detachments and central serous choroidopathy. It is recommended that individuals with macular degeneration test their eyes with the Amsler Grid daily. If any changes are noted, you should contact your optometrist immediately.
