First, rule out simple causes: repeat the test with your reading glasses on, in good light, keeping your eye on the dot. If the bend is still there, contact an eye doctor.

In a 2006 study of 140 people, it picked up 80% of eyes with wet (neovascular) AMD but only 30% with early AMD, and 15% of healthy people reported a false abnormality (Estreicher et al., 2026). In a 2024 primary-care study of 355 patients, sensitivity was 62.7% and specificity 81.3%.
