The QuantifEye instrument uses a psychophysical technique called heterochromic flicker photometry to measure macular pigment optical density (MPOD) in an area in the center of the retina, known as the macula.
By measuring the MPOD we can determine if the macula has more or less than the normal amount of macular pigment. Macular pigment is directly related to your risk for Macular Degeneration and is very important to track.
Macular Degeneration Prevention
Once the baseline MPOD score is established, we can actually raise a patient’s MPOD and improve protection against Age-related Macular Degeneration through zeaxanthin and lutein supplementation. Taking into account factors such as your age, family history, the appearance of your macula and your MPOD score, your eye doctor can determine and recommend individualized treatment.
How the test works
The QuantifEye machine tests the patient’s ability to see a flicker that the machine flashes. It has two parts to it. The first is checking your sensitivity level of blue and green light. Using different frequencies, the machine is able to come up with a luminance ratio. The ratio produces dots on a graph so that it easy to see if the patient has done well or not. It then tests all areas of your vision, including peripheral vision.
