Macular hard drusen in the right eye. 65-year-old diabetic woman. Drusen, from the German word for node or geode (singular, "Druse"), are tiny yellow or white accumulations of extracellular material that build up between Bruch's membrane and the retinal pigment epithelium of the eye. The presence of a few small ("hard") drusen is normal with ...
Geographic atrophy (GA), also known as atrophic age-related macular degeneration (AMD) or advanced dry AMD, is an advanced form of age-related macular degeneration that can result in the progressive and irreversible loss of retinal tissue (photoreceptors, retinal pigment epithelium, choriocapillaris) which can lead to a loss of central vision over time.
Optic disc drusen (ODD) are globules of mucoproteins and mucopolysaccharides that progressively calcify in the optic disc. [ 1 ] [ 2 ] They are thought to be the remnants of the axonal transport system of degenerated retinal ganglion cells .
Bruch's membrane thickens with age, slowing the transport of metabolites. This may lead to the formation of drusen in age-related macular degeneration. [4] There is also a buildup of deposits (Basal Linear Deposits or BLinD and Basal Lamellar Deposits BLamD) on and within the membrane, primarily consisting of phospholipids.
There are many eye conditions that can lead to vision disorder. Some of which are as follows: Age-Related Macular Degeneration (ARMD): ARMD is a retinal degeneration disease specifically associated with macula blood vessels, which can result in central vision impairment. It is strongly linked to advancing age, as well as European ancestry.
The infected also sport red eye color, and bleed from the eyes, mouth and nose. Rage plague Braindead: A disease carried by Sumatran rat-monkeys, found only on Skull Island, which kills victims and then reanimates them as zombie-like creatures that desire human flesh. Those who are killed will also reanimate as zombies.
Central serous chorioretinopathy (CSC or CSCR), also known as central serous retinopathy (CSR), is an eye disease that causes visual impairment, often temporary, usually in one eye. [ 1 ] [ 2 ] When the disorder is active it is characterized by leakage of fluid under the retina that has a propensity to accumulate under the central macula.
If the diagnostic workup reveals a systemic disease process, directed therapies to treat the underlying cause are required. If the amaurosis fugax is caused by an atherosclerotic lesion, use of aspirin as an anticoagulant is indicated, and a carotid endarterectomy considered based on the location and grade of the stenosis.
