8.7% global prevalence in 2020 [2] 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 ...
Photic retinopathy is damage to the eye 's retina, particularly the macula, from prolonged exposure to solar radiation or other bright light, e.g., lasers or arc welders. The term includes solar, laser, and welder's retinopathy and is synonymous with retinal phototoxicity. [1] It usually occurs due to staring at the Sun, watching a solar ...
Documentaries like the Oscar-winning Chernobyl Heart released in 2003, explore how radiation affected people living in the area and information about the long-term side effects of radiation exposure. [264] The Babushkas of Chernobyl (2015) is a documentary about three women who decided to return to the exclusion zone after the disaster. In the ...
Soviet Military authorities started evacuating people from the area around Chernobyl on the second day after the disaster (after about 36 hours).

[2] [3] [4] However, there is considerable debate concerning the accurate number of projected deaths that have yet to occur due to the disaster's long-term health effects; long-term death estimates range from up to 4,000 (per the 2005 and 2006 conclusions of a joint consortium of the United Nations) for the most exposed people of Ukraine ...
For decades, scientists have studied animals living in or near the Chernobyl Nuclear Power Plant to see how increased levels of radiation affect their health, growth, and evolution. A new study ...
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.
The fundus exam via ophthalmoscopy is essentially normal early on in cone dystrophy, and definite macular changes usually occur well after visual loss. Fluorescein angiography (FA) is a useful adjunct in the workup of someone suspected to have cone dystrophy, as it may detect early changes in the retina that are too subtle to be seen by ...
