Dark Adaptation

Dark adaptation testing is a valuable tool for detecting early signs of age-related macular degeneration (AMD), one of the leading causes of vision loss in older adults. This test assesses how quickly the eyes adjust from bright light to darkness, specifically measuring the function of the rods in the retina, which are responsible for night vision. In the early stages of macular degeneration, the ability to adapt to low light conditions is often compromised, even before noticeable symptoms or vision loss occur.

Unlike traditional eye exams, which might not detect early AMD, dark adaptation testing can reveal functional changes in the retina, providing crucial early insights into the disease. This early detection allows for timely intervention, helping to slow the progression of AMD before it significantly impacts vision. Treatment options like lifestyle changes, supplements, or monitoring can be introduced to manage the condition more effectively.

For patients at risk of AMD due to age, genetics, or other factors, dark adaptation testing offers a proactive approach to preserving vision. By catching macular degeneration in its earliest stages, patients can benefit from early treatment, reducing the risk of severe vision impairment and improving long-term eye health outcomes.
