Frequently Asked Questions

This app is available to people who have macular-related ailments, like macular degeneration, who need regular monitoring to look out for new or worsening vision loss.

The app is available on the Apple App Store for download and includes a 14-day free trial of all the features. An affordable subscription is available allowing you to take advantage of the Layered Results History.

Macular degeneration (AMD) is the leading cause of vision loss in people over the age of 50. AMD causes you to lose your central vision while not impacting your peripheral vision. There are two main types, “dry” AMD and “wet” AMD. Dry AMD is characterized by the gradual breakdown of macular cells, and wet AMD involves abnormal blood vessel growth under the macula.

Mark any distortions.

Distortions can appear as faded, darker, or areas that no longer “flicker” on the Static Field Assessment. On the Amsler grid, mark wavy, faded, missing lines, or puckered areas.

If you see these, outline the distortion.

Press continue. The app will record the test (no distortions noted). This will take you to the next portion of the test.

In the area of the macula, the part responsible for central vision, the structure becomes damaged. There’s a gradual breakdown of the light-sensitive cells and supportive tissue. In “wet” AMD, abnormal blood vessels grow under the macula, leading to leakage and scarring. This can lead to permanent vision loss if not treated.

Regular use of the app allows you to notice changes and seek timely medical attention, potentially helping manage the condition and slowing down the condition thus, preserving more vision.
