Macular Degeneration Vision Test

One good way of detecting macular degeneration is to use the Amsler grid.

Instructions on using the Amsler Grid:

  • While wearing glasses hold Amsler grid at a reading distance.
  • Cover one eye.
  • Stare at center dot.
  • Check to see if all the lines are straight and that all squares are the same size.
  • If any distortion, blur, discoloration or abnormality consistently occurs, see your ophthalmologist right away. Note: remember to test both eyes.
  • Do this test for each eye separately.

A person with macular degeneration may notice distortion of the grid pattern such as bent lines and irregular box shapes or a gray shaded area.
