Types of Amsler Grids found in this book:
- Standard black with White Grid
- Standard with Diagonals for Central Scotoma
- Black with Red Grid
- Black with White Dots
- Parallel Lines on Black
- Parallel Lines with Central Lines
- Standard with Small Central Squares
In addition to the Standard Grids, the Red on Black is used to diagnose a color scotoma. The White Dots Grid reveals a scotoma without distortion. The two Parallel Line Grids are used with patients needing a more simplified Amsler Grid and are presented both horizontally and vertically. Each of the Small Central Squares approximates 1/2 degree and is used for patients with small, central scotomata.
