Amsler, Charles D.

Charles D. Amsler was a renowned ophthalmologist known for developing the Amsler grid, a simple test used to detect vision problems related to the macula, part of the retina responsible for central vision. The grid helps identify early signs of conditions like macular degeneration by allowing individuals to notice distortions or missing areas in their central visual field. The test is straightforward: patients look at the grid and report any areas where lines appear wavy, blurred, or missing, prompting further eye examination if abnormalities are detected.
