The Elektron Tevhnology MPS II measures the density of pigment at the macula. Macular pigment affords protection against harmful blue and ultra-viloet light which can damage the retina and also can be a source of glare. Reduced macular pigment density has been shown to be a risk factor for age related macular degeneration. The test takes two or three minutes to carry out. Detection of low levels of pigment at the maculae will enable your optometrist or ophthalmologist to provide you with advice on nutrition which may include supplements of Lutein, Zeaxanthin and Meso-Zeaxanthin. Follow up tests will show whether the protective pigment levels increase over time with your dietary change.  Barnard Levit optometrists carry out this test on their own patients as well as for other patients patients referred by ophthalmologists and other optometrists for this test.
