The Ampler grid is designed to evaluate visual field deficiencies in how many degrees of central vision?

  1. 10 degrees

  2. 20 degrees

  3. 30 degrees

  4. 40 degrees

The correct answer is: 20 degrees

The Ampler grid is specifically designed to assess visual field deficiencies within a range of 20 degrees of central vision. This tool is particularly useful in identifying and quantifying central visual field loss, commonly seen in various ocular conditions such as age-related macular degeneration and glaucoma. The grid allows practitioners to determine how much of the visual field is functional and helps in planning appropriate management strategies for patients. By focusing on this specific range, the Ampler grid effectively captures crucial information about central vision that is vital for diagnosing and monitoring eye diseases.
