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 ]
Fundus of geographic atrophy. 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 over time.
The early stages of pellucid marginal degeneration may also be managed with soft contact lenses. [1] Success has been shown with the use of rigid gas permeable contact lenses combined with over-refraction. People wearing contacts don't report increased problems with glare and contrast sensitivity, but it is not clear if this is due to the ...
In some cases, dry macular degeneration can convert to “wet” degeneration, caused by “bleeding or a leaky blood vessel,” that leads to a much more rapid loss of visual acuity, explains ...
The onset of symptoms and the severity of vision loss vary widely. The adult-onset form begins later, usually in middle age, and tends to cause relatively mild vision loss. The two forms of vitelliform macular dystrophy each have characteristic changes in the macula that can be detected during an eye examination .

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 ...
