Macular degeneration is a disease of the elderly in which degenerative processes take place in the most sensitive part of the retina (film of the eye) which enables one to see fine details. The exact process by which this degeneration takes place is still not fully understood.

The initial symptoms are frequently that of distortion of vision, aberrations or changes of colour perception and actual reduction in the quality or resolution of vision, and change in shape and size of objects. Any of these symptoms should suggest to the person that they require careful retinal examination.

Presently, effective treatment can be given to only a small proportion of those developing macular degeneration and the treatment usually consists of laser treatment or, in newer developments, special dyes injected into the body with subsequent laser treatment. The aim of most of this treatment is to stop progressive loss of vision and in only a few cases is it likely to improve vision.

Much research is being undertaken in this field and it is likely that over the next decade, there should be major advances.

There is considerable contention in the scientific literature as to whether the use of oral vitamins or antioxidants have any effect in the prevention of this disease.
