Yes, cataracts can affect peripheral vision, although they primarily cause blurred or cloudy central vision. As cataracts progress, they can also impact the clarity of peripheral vision due to the overall clouding of the lens. This can lead to difficulties in seeing objects or movements on the sides, affecting daily activities and overall visual function. Regular eye examinations are important for monitoring cataract progression and determining the need for treatment.
Initially, cataracts may not affect vision.
no visual field testing is used to determine peripheral vision losses

PNS refers to the peripheral nervous system. Diseases that can affect the peripheral nervous system are diabetes, vasculitides, uremia and atherosclerosis.
Peripheral resistance
the cataracts of river nile blocked the way in waterways so it was difficult for the to travel through water so they used land ways
No, eye color is determined by the properties of the iris. Cataracts develop inside the lens, which is behind the iris. In very bad cases of cataracts the pupil can look cloudy or even white, but this does not affect the iris color.
Cataracts themselves do not move; they are typically stationary opacities that form on the lens of the eye. They develop gradually and can vary in size and density but remain fixed in their location on the lens. While cataracts can affect vision by clouding the lens, they do not shift or change position within the eye.
Yes, cataracts are made of acrylic and will not affect the MRI scan in any way.
People who smoke more than 25 cigarettes per day are three times as likely as nonsmokers to develop nuclear or PSC cataracts. Smoking does not appear to be related to cortical cataracts.
Cataracts do not directly destroy photoreceptors in the retina; instead, they cloud the lens of the eye, which leads to impaired vision. This clouding can cause light to scatter, resulting in blurry or distorted images. If left untreated, severe cataracts can lead to prolonged vision impairment, but the photoreceptors themselves remain intact. However, other underlying conditions may affect the photoreceptors independently of cataracts.
