Macular Pigment Density (MPOD) is a measure of the density of Macular Pigment (MP) in the center of the retina. Macular pigment absorbs damaging blue light. It functions a little like the eye’s own internal “sunglasses” and the denser the MP the more protective. Low or decreased MPOD is a risk factor for age-related macular degeneration (AMD). AMD causes gradual and often complete vision loss.
Healthy macular pigment enables clear 20/20 vision and vivid color vision. When macular pigment density decreases, vision is affected in the following ways:
Decreased visual acuity resulting in less clear vision perception
Less contrast sensitivity (harder to see a gray car on a gray road in the rain)
Slower glare recovery after viewing bright lights (bothered by headlights while driving at night)
Changes in light sensitivity
Difficulty with night vision
To support healthy macular pigment, patients must have the proper amounts of zeaxanthin and lutein. Because the body does not make these antioxidants on its own, they must be ingested. Lutein is commonly found in leafy greens, while brightly colored vegetables like corn and peppers contain zeaxanthin. It can be difficult to get the amounts of these retinal carotenoids to optimal levels in a regular diet. This is why we are proud to offer EyePromise Nutraceutical supplements to our patients. We are very excited to utilize the latest in macular pigment measurement, the QuantifEye MPS II. The QuantifEye MPS II densitometer is the most reliable and accurate device for measuring Macular Pigment Optical Density (MPOD). This test can be completed along with your routine eye exam.
Our office is excited to offer myopia master testing for all kids under 18! The myopia master measures axial length, or the size of the eyeball. As myopia increases, the eyeball gets longer, or axial length increases. Recent research in the field of myopia control has shown that measuring axial length is important, because the retina stretches as the eye gets longer with increasing myopia. A longer axial length is associated with developing eye diseases later on in life. The myopia master enables us to measure and track axial length over time, which helps us determine how well our myopia management programs are working.
