The MDD-2 Macular Adaptometer is a FDA Class 1 Medical Instrument
that measures photostress recovery in the visual field of the eyes, enabling the early detection of retinal disease.
MDD stands for Macular Degeneration Detection and the MDD-2 differe from other optical equipment such as the
OCT in that it measures the FUNCTION of the macular as opposed to viewing an image of the tissue to determine
presence of pathology.
Use of the MDD-2 to assess central retinal eye health elevates the quality of care
especially for those primary care doctors who may have no other way of determining central retinal (macular)
function and thus health.

How the MDD-2 test works
- The clinician places the viewing aperture of the instrument to the patients eye and performs the test monocularly.
- The patient is instructed to look into the viewing aperture and asked to align the "zero" image displayed to the center
of their vision by moving it accordingly.
- The patient is informed that a bright flash is displayed after which a digital numeral is displayed.
The patient should audibly speak the number once they are able to see it (this could take anywher from 5 o 90 seconds)
- When the patient speaks the number, the clinician depresses the button and a time measurement is taken.
- Based on the measurement, the physician interprets the result and makes an appropriate recommendation.
