What Is AdaptDx Pro®
AdaptDx Pro® delivers objective results with a non-invasive assessment that’s easy to administer. AdaptDx is not only much faster than older methods, but also more sensitive and specific.
The AdaptDx Pro® can help detect AMD at its earliest stages and before visual acuity is impacted. The AdaptDx Pro® has proven to be 90% sensitive and 90% specific for the presence of AMD.
Testing For AMD
Age-related macular degeneration is the leading cause of vision loss in Americans over age 60, and presents itself in two forms: dry macular degeneration and wet macular degeneration. Of the two, the “dry” form is far more common. Both affect the center region of the retina, the light-sensitive area in the back of the eye responsible for processing images we see.
According to recent studies, at least 25% of AMD is undiagnosed by primary eyecare professionals in a dilated fundus examination. By using the AdaptDx Pro®, they have more than doubled their diagnosis of AMD patients who otherwise might not have been identified until vision loss occurred.
AdaptDx Pro® automated dark adaptometer is the cornerstone, enabling eye care professionals to detect subclinical AMD and evaluate disease progression to help reduce preventable vision loss by up to 87%.
The AdaptDx Pro® Testing Procedure
The AdaptDx Pro® is very similar in form and operation to the familiar visual field perimeters. A routine dark adaptation test with the AdaptDx Pro® takes as little as five minutes per eye. The testing is conducted in a darkened room and is completely non-invasive, with nothing touching the patient’s eye.
Measurement starts by exposing the test eye to a mild flash to pre‐condition the retina to a standard photobleached state. The patient is then asked to focus on a fixation light and indicate with a hand-held response button when a stimulus light appears. Stimulus lights are presented at a fixed location using a pattern of generally decreasing intensities to determine visual sensitivity recovery.
The overall testing procedure consists of the following steps:
- Refract test eye (to determine appropriate trial lenses)
- Enter patient information in AdaptDx Pro® (name, age, gender, etc.)
- Patch non‐test eye
- Place appropriate trial lenses in AdaptDx Pro® (if needed)
- Align patient to AdaptDx Pro®
- Enter test information in AdaptDx Pro® (protocol, test eye, pupil size, etc.)
- Conduct demonstration test with AdaptDx Pro®
- Conduct actual test with AdaptDx Pro®
