Normal vision The same view with age-related<unk> . Early or intermediate AMD may be asymptomatic, or it may present with blurred or decreased vision in one or both eyes. This may manifest initially as difficulty with reading or driving (especially in poorly lit areas). Other symptoms of AMD include distortion of vision and blind spots (especially in and around the central visual field). Other signs and symptoms of<unk>  include: ; * Distorted vision in the form of metamorphopsia, in which a grid of straight lines appears wavy and parts of the grid may appear blank: Patients often first notice this when looking at things like miniblinds in their home or telephone poles while driving. There may also be central scotomas, shadows or missing areas of vision * Slow recovery of visual function after exposure to bright light (photostress test) * Visual acuity drastically decreasing (two levels or more), e.g.: 20/20 to 20/80 * Blurred vision: Those with nonexudative<unk>  may be asymptomatic or notice a gradual loss of central vision, whereas those with exudative<unk>  often notice a rapid onset of vision loss (often caused by leakage and bleeding of abnormal blood vessels). * Trouble discerning colors, specifically dark ones from dark ones and light ones from light ones * A loss in contrast sensitivity *Formed visual hallucinations and flashing lights have also been associated with severe visual loss secondary to wet AMD<unk>  by itself will not lead to total blindness. For that matter, only a small number of people with visual impairment are totally blind. In almost all cases, some vision remains, mainly peripheral. Other complicating conditions may lead to such an acute condition (severe stroke or trauma, untreated glaucoma, etc.), but few<unk>  patients experience total visual loss. The area of the<unk> comprises only about 2.1% of the retina, and the remaining 97.9% (the peripheral field) remains unaffected by the disease. Even though the<unk> provides such a small fraction of the visual field, almost half of the visual cortex is devoted to processing<unk>  information. In addition, people with dry<unk>  often do not experience any symptoms but can experience gradual onset of blurry vision in one or both eyes. People with wet<unk>  may experience acute onset of visual symptoms.
