yellow or white deposits in a layer of the retina called bruchs membrane. they are the most common early sign of dry age related macular degeneration. drusen are made up of lipids a type of fatty protein. they may be the result of a failure of the eye to dispose of waste products that are produced when the photoreceptors of the eye drop off older parts of the cell. wet macular degeneration wet

loss caused by macular degeneration. wet macular degeneration with this type the membrane underlying the retina thickens then breaks. the oxygen supply to the macula is disrupted and the body responds by growing new abnormal blood vessels. these begin to grow through the breaks of the membrane behind the retina towards the macula often raising the retina. wet macular degeneration to visualize this imagine the roots of a tree growing and spreading until they crack and grow through a sidewalk. then imagine rainwater seeping up throughout the cracks. these abnormal blood vessels the roots tend to

macular pigment optical density this is an instrument that measures the level of lutein and zeaxanthin harmful light protecting pigment in the macula . the common machines you will hear about are quantifeye mpsii and macuscope. there is not agreement on use of mpod machines. it is not covered by insurance. other tests you may hear about preferential hyperacuity perimeter php this is a new approach to find early wet amd in patients who already have dry amd. it uses the ability to detect small misalignment in lines called hyperacuity it is known as foresee php commerically. it is not covered by insurance. other tests you may hear about genetic testing– commercially available as macular risk and is done using a simple cheek swab. it is currently not typically done and does not affect treatment of particular amd cases. the cost of the macula risk genetic test can be from several hundred dollars to a few thousand dollars and insurance may not cover the cost of the testing.
