The eye care professional may also ask the patient to look at an Amsler grid
. Changes in central vision may cause lines to disappear or appear wavy with retinal disorders.
(I solved that problem by planning to use the Amsler Grid
chart; if the apparent wavy lines started to appear straight, then I would know I was working in the right direction.)

You can obtain an Amsler grid
from your health care professional and do this simple test yourself to monitor symptoms of wet AMD.
Known as an Amsler Grid
, the chart looks like graph paper with a black dot in the center.
The eye health testing, held at stores with a pharmacy and/or optical center, included a vision acuity screening as well as a quick take-home test called an Amsler Grid
, which screens for blurred or missing areas of vision.
One way to monitor your eyes to see if you need to visit an ophthalmologist is to check your vision regularly using an Amsler grid
. This simple test may help you detect changes in your vision that you otherwise might miss.
One tool developed at the USAMRD for clinical evaluation/triage of potential and actual laser induced retinal injury patients is the Aidman Vision Screener* and Amsler Grid
It has long been recognized that, presumably because of perceptual completion (or "filling in"), more than 40% of persons with definite scotomas in their central visual field cannot detect them on an Amsler grid
(Fine et al., 1986; Schuchard, 1993).
One way to tell if you're experiencing AMD is to take an Amsler grid
* Monitor your vision regularly with an Amsler grid
, a basic test for checking your central visual field.
* With older patients, suspect ARMD if vision has decreased or if Amsler grid
testing reveals scotoma or metamorphopsia (C).
I check my eyesight with the Amsler grid
every day and try to eat plenty of fruits and vegetables.
Ask your eye doctor for an Amsler grid
so you can monitor your eyes at home.
Fink, who is also a visiting research assistant professor of ophthalmology at the University of Southern California in Los Angeles, developed the three-dimensional, computer-based Threshold Amsler Grid
Test as part of his postdoctoral research while at the California Institute of Technology in Pasadena, with his colleague Alfredo Sadun, a professor of ophthalmology at USC.
