Drusen (Definition) Drusen are small yellow or white deposits of material that build up between the retina and the retinal pigment epithelium of the eye (beneath the retina). It is normal for people to have some drusen in the eye, usually after age 40. Drusen in the macula increase the risk for age-related macular degeneration,...
Does drusen cause vision loss?
The presence of small drusen is normal and does not cause vision loss. However, the presence of large and more numerous drusen raises the risk of developing advanced dry AMD or wet AMD.

What are drusen like?
Drusen are like tiny pebbles of debris that build up over time. There are two different types of drusen: soft and hard. “soft” drusen are large and cluster closer together. “hard” drusen are smaller and more spread out. Having a few hard drusen is normal as you age. Most adults.
How do you know if you have drusen?
Most people don’t know they have drusen until they’re discovered by an eye doctor (ophthalmologist or optometrist) during a routine eye exam. Drusen can be seen during a dilated eye exam using an ophthalmoscope, a device that allows the doctor to see the retina and back of the eye.
Why is macular degeneration called age related?
It’s called “age-related” macular degeneration because it’s more common in people older than 60. As soft drusen get larger, they can cause bleeding and scarring in the cells of the macula. Over time, AMD can result in central vision loss.
What to do if you see soft drusen?
If your eye doctor detects many soft drusen on an eye exam, they’ll likely want to run additional tests for age-related macular degeneration. The ophthalmologist may also ask you questions about any other symptoms you might be experiencing.

What are the yellow deposits under the retina?
Drusen are small yellow deposits of fatty proteins (lipids) that accumulate under the retina.
Why do people have central vision?
Central vision allows us to focus on details straight ahead. People with more soft and larger drusen, are at higher risk of experiencing this type of vision loss in the future than people with fewer and smaller drusen. This is because the presence of many soft drusen developing under the macula (the small area in the center of the retina) ...
What are retinal drusen?
Retinal drusen are yellow-colored deposits made up of proteins and lipids that form behind the retina of the eye. The retina is a layer of cells that line the inside surface of the back of the eye and transmit information to the brain, allowing you to see.

What are the conditions associated with the peripheral retina?
T here are a number of clinical conditions associated with the peripheral retina, including primary lesions such as pars plana cysts. Some are degenerative, with potential vision-threatening consequences. Others are associated with systemic disease and may better correlate with the patients’ presenting signs and symptoms.
How to tell if retinoschisis is acute or chronic?
Differentiating retinoschisis from RRD can be a challenging task. 10 Shallow retinoschisis can resemble a chronic RRD. Distinguishing factors between the two include the absence of a demarcation line that is associated with RRD, as well as the absence of a full-thickness retinal hole or break. Bullous retinoschisis can appear as acute RRD. A patient’s symptomatology and the presence or absence of retinal breaks helps aid in telling the two apart ( Figure 15 ). Patients with RRD often are or eventually become symptomatic; whereas, in most cases, retinoschisis is a coincidental finding. OCT can assist in differentiating between the two ( Figure 16 ). Slit lamp assessment may also be a helpful option, as the tool can determine whether the patient is able to see the light. Patients with retinoschisis will also have an absolute scotoma in the affected area, obstructing their vision.
What is the term for a split in the retina?
Peripheral acquired or age-related retinoschisis is a splitting in the neurosensory retina. This idiopathic and often progressive condition can result in bullous or balloon-like areas in the temporal or inferotemporal retinal periphery ( Figure 14 ). On clinical examination, these lesions can have a wide range of widths and heights. They usually have small glistening or refractile deposits known as Gunn’s dots, which are seen in the inner area of the schisis cavity ( Figure 14 ).
Is peripheral reticular degeneration a macular degeneration?
Peri pheral drusen and peripheral reticular degeneration (PRD) are common and often underreported peripheral retinal findings that can be seen in patients with or without macular degeneration. Although these are both related to age, they are two distinct conditions with two different phenotypes and should be treated as such. As they are alterations of the outer retina, they do not pose a risk for RRD. However, the phenotypic (clinical, OCT and angiographic) findings of peripheral degeneration are similar to those of macular drusen ( Figure 8 ). Reticular pigmentation appears as a net-like pigmented structure that may look similar to the pigmentary abnormalities associated with macular degeneration ( Figure 9 ).
Is microcystoid degeneration intra retinal?
Peripheral microcystoid degeneration is the most common intra-retinal degeneration. 8,9 Clinically, microcystoid degeneration presents as small, yellowish bubble-like aggregates in the retinal periphery ( Figure 12 ). On OCT, it appears as small cystic spaces involving the inner nuclear and outer plexiform layers ( Figure 13 ). In itself, microcystoid degeneration is a benign condition; however, it is often a precursor to peripheral acquired retinoschisis. 8
Is drusen a marker of Alzheimer's?
4 Additionally, peripheral drusen have also been considered a potential marker for Alzheimer’s dementia (AD). Peripheral drusen and degeneration should not be used as diagnostic indicators for AD or AMD but should encourage practitioners to more thoroughly monitor patients with these two peripheral retinal degenerative conditions. 5
