Macular Degeneration

The break down of macula the light sensitive area in the centre of the retina that controls the central visual field and the ability to see color, as a result eyesight is impaired only the peripheral vision remain intact the centre of the vision gets blurry, grey or filled with large blank spot. Which makes it difficult to read, drive and recognizing someone’s face.

Macular degeneration can be of two types, one is age related as the as macula thins and bits of debris gather beneath the macula with age, this condition develops slowly.
Second is haemorrrhagic macular degeneration where new blood vessels grow underneath the retina this leads to the breakage of fragile vessels which leaks fluid and blood causing scar tissues to form and central vision deteriorate rapidly.

The main cause of macular degeneration is high fat diet, smoking and exposure to sunlight. Heart disease, high blood pressure and diabetes may also be the contributing factor.

The usual symptoms of macular degeneration are faded and washed out color, blurry grey or blank spot in the centre of the field of vision and distorted vision, printed word looks burred, objects appears to be the wrong shape and size.


Supplements of antioxidants like vitamin C and vitamin E and different types of carotenoids can neutralize the free radicals linked to macular degeneration. As zinc plays a key role in the functioning of the retina, supplements of zinc is also very effective.

Wearing sunglasses to protect the eyes from direct sunlight, not smoking and eating a lot fruits and green leafy vegetables, can slow down the process of macular degeneration.
