How is AMD diagnosed?

Eye Test — Fri, 27 Feb 2009 12:52:24 +0000

Optometrists are qualified to test sight and carry out investigation for eye diseases. If the optician detects a problem you may be referred to your GP or directly to see an Ophthalmologist, specialist in diagnosis and treatment of eye diseases.

Diagnosis Eye Disease

Eye drops will be used to dilate your pupils, this will cause the pupil to increase in size dramatically, allowing a better view of the retina and macula. Some may show you an Amsler Grid which is a grid of a black background with the horizontal and vertical white line across the grid.

What are the Combined Risk Factors for AMD?

Eye Test — Fri, 27 Feb 2009 12:46:54 +0000

AGE:
The main risk factor for developing AMD. Commonly described as ‘wear & tear’, the older you grow, the more risk of developing AMD increases. AMD is the leading cause of vision loss in people aged 65 in the UK.

DIET & NUTRITION:
Macular cells are susceptible to damage from free radicals. These highly oxygen charged molecules builds up over years of dietary neglect. Research points to low intake of antioxidants and high fat diets as the factor for increased risk of developing AMD. Excessive alcohol consumption can deplete antioxidants.

SUNLIGHT:
Macular cell damage can result from sunlight and UV exposure. Light coloured iris and those exposed to blue light are at more risk of AMD.

GENETICS:
AMD is not hereditary, but people with family history have a chance of developing the condition themselves.

SMOKING:
AMD is twice as common in people who smoke (20+ cigarettes) compared with non-smokers. This again relates to loss of protective antioxidants reaching the eye, causing free radicals to damage the eye.

GENDER:
Women over 75 have double the chances of developing AMD compared to a man of the same age.
