Geographic atrophy (GA), also known as atrophic age-related macular degeneration (AMD) or advanced dry AMD, is an advanced form of age-related macular degeneration that can result in the progressive and irreversible loss of retinal tissue (photoreceptors, retinal pigment epithelium, choriocapillaris) which can lead to a loss of central vision ...
In advanced stages of AMD, atrophy of the RPE (geographic atrophy) and/or development of new blood vessels (neovascularization) result in the death of photoreceptors and central vision loss. [citation needed] In the dry (nonexudative) form, drusen accumulates between the retina and the choroid, causing atrophy and scarring to the retina. In the ...
Molnupiravir, sold under the brand name Lagevrio, is an antiviral medication that inhibits the replication of certain RNA viruses. [7] It is used to treat COVID‑19 in those infected by SARS-CoV-2 . [ 7 ]
Dominant optic atrophy was first described clinically by Batten in 1896 and named Kjer’s optic neuropathy in 1959 after Danish ophthalmologist Poul Kjer, who studied 19 families with the disease. [3] Although dominant optic atrophy is the most common autosomally inherited optic neuropathy (i.e., disease of the optic nerves), it is often ...
Posterior cortical atrophy (PCA), also called Benson's syndrome, is a rare form of dementia which is considered a visual variant or an atypical variant of Alzheimer's disease (AD). [ 1 ] [ 2 ] [ 3 ] The disease causes atrophy of the posterior part of the cerebral cortex , resulting in the progressive disruption of complex visual processing . [ 4 ]
Relative to the Census 2000, all geographic regions demonstrated positive growth in the population of adults aged 65 years and older and 85 years and older. The most rapid growth in the population of adults aged 65 years and older was evident in the West (23.5%), which showed an increase from 6.9 million in 2000 to 8.5 million in 2010.
As with other forms of ataxia, SCA frequently results in atrophy of the cerebellum, [5] loss of fine coordination of muscle movements leading to unsteady and clumsy motion, and other symptoms. Ocular deficits can be quantified using the SODA scale. [6] The symptoms of an ataxia vary with the specific type and with the individual patient.
Corticosteroid-induced lipodystrophy (CIL) is a condition of abnormal fat deposition caused by corticosteroid medications. [1] Fat accumulates in the facial area ("moon face"), dorsocervical region ("buffalo hump"), and abdominal area ("pot belly" or "beer belly"), whereas the thickness of subcutaneous fat in the limbs is decreased.
