Macular degeneration is a medical condition where the light sensing cells in the macula malfunction and over time cease to work. According to the American Academy of Ophthalmology, it is the leading cause of central vision loss (blindness) in the United States today for those over the age of fifty. There are two basic types of the disease: Standard Macular Degeneration (MD) and Age Related Macular Degeneration (ARMD), with ARMD being the most common form of the condition. Macular degeneration that is not age related is most commonly c ...

Dharma-Ending Age, Degenerate Age, Last Age.

The present spiritually degenerate era, twenty-six centuries after the demise of Shakyamuni Buddha. The concept of decline, dissension and schism within the Dharma after the passing of the Buddha is a general teaching of Buddhism and a corollary to the Truth of Impermanence. See, for example, the Diamond Sutra (sect. 6 in the translation by A.F. Price and Wong Mou-lam).

The time following Buddha Shakyamuni's demise is divided into three periods:

i)               the Perfect Age of the Dharma, lasting 500 years, when the Buddha's teaching (usually meditation) was correctly practiced and Enlightenment often attained;

ii)             the Dharma Semblance Age, lasting about 1,000 years, when a form of the teaching was practiced but Enlightenment seldom attained;

iii)            the Dharma-Ending Age, lasting some ten thousand years, when a diluted form of the teaching exists and Enlightenment is rarely attained.

Genshin (源信 942–1017) was the most influential of a number of evangelists active during the eleventh and twelfth centuries in Japan. He espoused a doctrine of Amidism which taught that because Japan was thought to have entered mappō, the "degenerate age" of the "latter law," the only hope for salvation lay in the reliance on the power of Amitabha. Other doctrines, he claimed, could not aid an individual because they depended on "self-power" (jiriki), which cannot prevail during the chaos of the degenerate age, whe

Spondylosis is the degeneration of the vertebral processes and formation of osteophytes. It commonly occurs with aging. Often there is herniation of the nucleus pulposus. Compression of the nerve roots is accompanied with sensory and motor disturbances and pain. Spondylosis is a deformity of the joint of two vertebrae, particularly of the neck, where as the space between the two adjacent vertebrae narrows, this result in pressing upon the nerves emerging from the spinal cord and result in sev ...

Most of the Big Bang theory's events are inferred from telescopic observations, particle accelerator experiments, and mathematical algorithms. These methods can reach deep into the past to tell us what occurred back then, but human beings are on their own when it comes to forecasting what is to come. It really is impossible to say what exactly might happen in the distant future. We can only infer what the Universe will be like. So as observations and theory become more fine-tuned, so will the timeline ...

According to the Big Bang theory, a sequence of events described below is believed to have taken place starting (13.7 ± 0.2) x 109 years ago (see Hubble's law), a time at which in general relativity there is a gravitational singularity. General relativity cannot describe the Universe at this time, because the theory gives infinite values for the temperature and density of the universe. It is believed that general relativity is insufficient to make predictions about the very beginning of the universe and that such predictio ...

Timeline of the Big Bang - Scenario A: The Big Rip. This scenario is possible only if dark energy increases over time as the Universe expands. It's highly speculative since dark energy is poorly understood and it's questionable if it varies over time to such a degree that it causes every atom in the Universe to tear apart from the inside out. The summary of the theory goes that given enough time, not only do galaxies race away from each other but eventually so do stars, then planets, and eventually atoms and als ...

The crucial factor in the development of OA is the wearing out and eventual disappearance of synovium, and later, all cartilage of the affected joints. OA may be divided into two types: Primary OA: This type is caused by ageing. As a person ages, the water content of the cartilage increases, and the protein composition in it degenerates, thus degenerating the cartilage through repetitive use or misuse. Inflammation can also occur, and stimulate new bone outgrowths, called "spurs" (osteophyte), to form around the joints. Sufferer ...

Shinran's thought was strongly influenced by the doctrine of mappō (末法), or the decline of the Dharma (the Buddhist teachings). Shinran saw the age he was living in as being a degenerate one where beings cannot hope to be able to extricate themselves from the cycle of birth and death through their own power, or jiriki (自力). For Shinran, all conscious efforts towards achieving enlightenment and realizing the Bodhisattva ideal were contrived and rooted in selfish ignorance; for humans of this age are so deeply rooted in ...

There is epidemiological evidence of a relationship between low plasma concentrations of lutein and zeaxanthin on the one hand, and the risk of developing age-related macular degeneration (AMD) on the other. Some studies support the view that supplemental lutein and/or zeaxanthin help protect against AMD. There is also epidemiological evidence that increasing lutein and zeaxanthin intake lowers the risk of cataract development. ...

Pterygium is characterized by elastotic degeneration of collagen and fibrovascular proliferation. It has an advancing portion called the head of the pteygium, which is connected to the main body of the pterygium by the neck. Sometimes a line of iron deposition can be seen adjacent to the head of the pterygium called Stocker's line. As it is a benign growth, it requires no treatment unless it grows to such an extent that it covers the pupil, obstructing vision. Wearing protective sunglasses with side shields will help prevent their formation or stop further growth. Occasionally found as an incidental finding in middle aged patie ...

The condition is marked by progressive deterioration, hepatosplenomegaly, dwarfism, gargoyle-like facies. There is a progressive mental retardation, with death occuring by the age of 10 years. Developmental delay is evident by the end of the first year, and patients usually stop developing between ages 2 and 4. This is followed by progressive mental decline and loss of physical skills. Language may be limited due to hearing loss and an enlarged tongue. In time, the clear layers of the cornea become clouded and retinas may begin to degenerate.

The clinical presentations is largely dependant on the age of onset of the disease. The most frequent type is the childhood-onset one, which normally occurs in males between the ages of 5 and 10 and is characterized by failure to develop, seizures, ataxia, adrenal insufficiency and degeneration of visual and auditory function. In the adolescent-onset form, the spinal cord dysfunction is more prominent and therefore is called adrenomyeloneuropathy or "AMD". The patients usually present with weakness and numbness of the limbs and urination or defecation problems. Most victims of this form are also males, although female ...
