Amsler, Walter

Walter Amsler was a Swiss ophthalmologist best known for developing the Amsler Grid, a simple tool used to assess vision and detect issues like macular degeneration. The grid consists of a pattern of straight lines with a central dot; patients focus on the dot while observing the lines. Distortions, such as wavering or missing lines, can indicate problems with the macula, the part of the eye responsible for central vision. The Amsler Grid is an essential tool for early detection of visual changes, helping guide timely medical intervention for eye health.
