Caption: In dry AMD, deposits called drusen
form on the macula and cause it to break down over time.
The presence of drusen
is a diagnostic criterion for early AMD and also gives information about disease progression.
It has been hypothesized that deposition of complement pathway complexes on and around the choriocapillaris could be related to the choriocapillaris loss observed since early AMD, correlating with the abundance and size of drusen
, A[beta] is localized in vesicular components known as "amyloid vesicles" or "amyloid assemblies" [43, 78] and exhibits several shapes, diameters, and fusion processes.

in patient-derived hiPSC-RPE models of macular dystrophies," Proceedings of the National Academy of Sciences, 2017; 201710430 DOI: 10.1073/pnas.1710430114
The study also showed that patients who took the beta-carotene version of the AREDS formula and who were former smokers had an increased risk of developing lung cancer.[sup] The AREDS2 is underway to determine the effect of other vitamin supplements, such as lutein, zeaxanthin, and omega-3 polyunsaturated fatty acids [Table 1], to see whether this combination can further slow the progression of vision loss from dry AMD.[sup] A number of proposed in the Complications of AMD Prevention Trial, did not demonstrate clinically significant reduction of vision loss in patients with large drusen
.[sup] The goal of treating dry AMD is to target the underlying cause of the disease and prevent.
The inflammatory proteins play contributory role in the progression of the disease that results into increased number of drusen

are extracellular deposits of debris that accumulate between RPE and Bruch's membrane.
ARMD highly correlates with aging and is primarily caused due to the formation of cellular debris, also known as drusen
, within retinal and choroidal pathology.
Dry form of AMD affects approximately 80-90% of individuals with AMD  and in this type of macular degeneration, extracellular small white or yellowish deposits (made up of lipids, a type of fatty protein), called drusen
, accumulated between the Retinal Pigment Epithelium (RPE) and the inner collagenous layer of Bruch's membrane (vitreous lamina).
Current high resolution optical coherence tomography devices provide ample new information on retinal layers, drusen
characteristics and their interaction.
