Peripheral retinal drusen and reticular pigment are associated with AMD and with CFHY402H and CFHrs1410996 genotypes, adjusting for AMD grade. These phenotypes may be a marker of genetic susceptibility for patients with or without AMD.
Drusen are yellow deposits under the retina. Drusen are made up of lipids and proteins. Drusen likely do not cause age-related macular degeneration (AMD). But having drusen increases a person's risk of developing AMD, and they may be a sign of AMD. There are different kinds of drusen.
Drusen are the defining feature of macular degeneration. These small yellow or white spots on the retina can be detected by an ophthalmologist during a dilated eye exam or with retinal photography. People with more than a few small drusen are said to have early age-related macular degeneration (AMD).
Drusen are about the width of a pinhead and are composed of a mixture of proteins and lipids (naturally occurring molecules that include fats). They often cause no symptoms, but can occasionally cause visual distortion if they are very large and near the center of the retina.
Drusen are typically associated with age-related macular degeneration in people over the age of 60; however they can arise as hereditary degenerations in young people. Drusen are a risk factor for macular degeneration but having drusen does NOT mean you have macular degeneration.
Dry macular degeneration occurs when light-sensitive cells in the macula slowly break down from accumulation of small yellow deposits called drusen.
Retinal drusen (say "DROO-zun") are tiny yellow spots that build up under the retina in your eye. They are made up of proteins and fatty substances (lipids). The retina is the nerve layer at the back of the eye that sends images to your brain. There are two kinds of drusen.
There's no treatment available for drusen and they sometimes disappear on their own, but if an eye doctor notices drusen under your retina during an eye exam, they'll likely want to monitor your eyes regularly for any changes.
Hard vs. Soft Drusen. “Hard” drusen are small, and indicate lower risk of future vision loss than “soft” drusen, which are larger, cluster together, and have edges that are not as clearly defined.
Likewise, in AMD, cholesterol is known to accumulate in the eye, within deposits called drusen. The study, published in Cell Metabolism, shows that large cells called macrophages appear to play a key role in clearing cholesterol from the eye, and that with aging, these cells become less efficient at this task.
A small clinical trial at Harvard has shown that some patients with very large drusen in the center of the retina can have their drusen size reduced and vision improved by a relatively high dose statin treatment.
Drusen are important risk factor for neovascular age-related macular degeneration (AMD) and have a dynamic nature as they can enlarge, newly form, or disappear over time.

Large, soft drusen are associated with a greater risk for developing advanced age-related macular degeneration (AMD), including choroidal neovascularization (CNV) and geographic atrophy [1]. Drusen have a dynamic nature as they can enlarge, newly form, or disappear over time [2-4].
Likewise, in AMD, cholesterol is known to accumulate in the eye, within deposits called drusen. The study, published in Cell Metabolism, shows that large cells called macrophages appear to play a key role in clearing cholesterol from the eye, and that with aging, these cells become less efficient at this task.
It can take an entire decade for it to progress from the early to the late stage. You will not be able to spot drusen on your own but will need an eye doctor's expertise and equipment to do so. Your doctor may spot drusen in a routine eye exam, and also may request that you come in for more frequent eye exams.
Degenerative drusen is an asymptomatic, bilateral, symmetric, yellow-white nodular thickening of the retinal pigment epithelium. Over time, the lesions may coalesce and form a honeycomb appearance, or they can enlarge. Drusen are often associated with pigment clumping, chorioretinal atrophy and choroidal neovascular membrane (CNVM). The onset of clinical signs may be seen by age 20-30 years. The onset of clinical symptoms occurs in the third to fourth decade of life and may involve an associated exudative or non-exudative retinal detachment, at the level of the retinal pigment epithelium.

TREATMENT OPTIONS. There is no treatment for degenerative drusen. If complications arise from the drusen, they are treated according to the cause. Routinely monitor patients for choroidal neovascularization membrane (CNVM) formation and choroidal/retinal detachments.
