Age-related macular degeneration (AMD)

Is a medical condition which usually affects older adults and results in a loss of vision in the center of the visual field (the macula) because of damage to the retina. It occurs in “dry” and “wet” forms. It is a major cause of blindness and visual impairment in older adults. Macular degeneration can make it difficult or impossible to read or recognize faces, although enough peripheral vision remains to allow other activities of daily life.

Dry AMD

Central geographic atrophy, the “dry” form of advanced AMD, results from atrophy to the retinal pigment epithelial layer below the retina, which causes vision loss through loss of photoreceptors (rods and cones) in the central part of the eye.

 

No medical or surgical treatments are currently available for this form of the condition, however vitamin supplements with high doses of antioxidants, lutein and zeaxanthin, have been suggested by the National Eye Institute and others to slow the progression of dry macular degeneration and, in some patients, improve visual acuity. The following link gives more information about the eye supplement Nutrof Total, which we recommend and use ourselves.

  • We supply a range of daylight and LED lamps
 

We run a Low Vision clinic to offer advice for those with early and advanced macular degeneration. We can provide information on the best forms of lighting to maximise available vision and advice on visual and non visual strategies to help cope. We also stock a large range of magnifiers which can provide much needed help when trying to read.

Wet AMD

Neovascular or exudative AMD, the “wet” form of advanced AMD, causes vision loss due to abnormal blood vessel growth (choroidal neovascularization) in the deeper layers of the retina, ultimately leading to blood and protein leakage below the macula. Bleeding, leaking, and scarring from these blood vessels eventually cause irreversible damage to the photoreceptors and rapid vision loss if left untreated. Only about 10% of patients suffering from macular degeneration have the wet type.

 

If you have wet AMD, the symptoms of blurred central vision appear more suddenly than they do in dry AMD. You may also experience other symptoms such as:



  • Visual distortions. For example, straight lines may start to appear wavy or crooked.

  • Blind spots. A blind spot usually appears in the middle of your visual field. The longer a blind spot is left untreated, the larger it will become. This is known as a central scotoma.
