Macular degeneration, also known as age-related macular degeneration (AMD or ARMD), is a medical condition which may result in blurred or no vision in the center of the visual field. [1] Early on there are often no symptoms. [1] Over time, however, some people experience a gradual worsening of vision that may affect one or both eyes. [1]
Blue light, a type of high-energy light, is part of the visible light spectrum. High-energy visible light (HEV light) is short-wave light in the violet/blue band from 400 to 450 nm in the visible spectrum, which has a number of purported negative biological effects, namely on circadian rhythm and retinal health (blue-light hazard), which can lead to age-related macular degeneration.
Metamorphopsia is a symptom of several common retinal and macular diseases, therefore treating the underlying disorder can improve symptoms. For people who have conditions such as epiretinal membrane (ERM), macular holes and retinal detachment , decreased metamorphopsia is associated with an increase in visual acuity . [ 4 ]
The supplements — called AREDS 2 — can be bought over the counter, but are intended to be used only by people who have been diagnosed with macular degeneration, and you should talk to your eye ...
Age-related macular degeneration (AMD) is a disease that affects the eyes and can lead to vision loss through break down of the central part of the retina called the macula. Degeneration can occur in one eye or both and can be classified as either wet (neovascular) or dry (atrophic).
Macular degeneration: Macular degeneration cause loss of central vision, blurred vision (especially while reading), metamorphopsia (seeing straight lines as wavy), and colors appearing faded. [11] Macular degeneration is the third main cause of blindness worldwide, and is the main cause of blindness in industrialised countries.
Micropsia is a condition affecting human visual perception in which objects are perceived to be smaller than they actually are. Micropsia can be caused by optical factors (such as wearing glasses), by distortion of images in the eye (such as optically, via swelling of the cornea or from changes in the shape of the retina such as from retinal edema, macular degeneration, or central serous ...
Layers of the eye, with the choroid labelled. Choroidal neovascularization (CNV) is the creation of new blood vessels in the choroid layer of the eye.Choroidal neovascularization is a common cause of neovascular degenerative maculopathy (i.e. 'wet' macular degeneration) [1] commonly exacerbated by extreme myopia, malignant myopic degeneration, or age-related developments.
