A new NHS treatment is offering hope to the 250,000 UK sufferers
of wet macular degeneration. The revolutionary surgical procedure uses beams of
radiation to destroy the abnormal blood vessels at the back of the eye that are
the cause of sight loss.
Early symptoms of wet
AMD can be as terrifying as they are debilitating - faces are blurred, blind
spots appear in the centre of vision and straight lines seem to waver. If left
untreated, patients can lose their sight within three months.
Tim Jackson,
consultant eye surgeon at King's College Hospital in London, says: 'This is a
relatively straightforward procedure. And unlike the injections, which need
repeating on a regular basis, the beauty of this technique is that it is a
one-off treatment.
'By killing the
abnormal blood vessels that cause the problem, you can produce a permanent
benefit rather than just suppressing the disease.'
The most common side
effect is that it can speed up the development of cataracts in patients who
have not undergone cataract
The technique, now
available on the NHS, is being trialled on 363 patients at 15 hospitals around
the country. Researchers are appealing for more participants. The radiation
therapy costs about £6,000 privately. So far, the results have been
encouraging. Preliminary studies show that 91 per cent of patients maintain
vision.
One success story is
that of Margaret Findlay, 84, from South London. Margaret had always been
staunchly independent, so when two years ago she rapidly started to lose her
sight, it was all the more difficult to come to terms with.
Within weeks, she had
to give up driving and ask family and friends for help with chores, especially
shopping.
'My eyesight
deteriorated so quickly it was devastating. I had to ask for lots of help,' she
says. 'I also had to give up my other passion of reading, which was a great
pity because all my life I've loved books - I'll read anything in print.'
When she saw her GP in
February 2007, he referred her to Mr Jackson, who diagnosed wet AMD. He offered
her epimacular brachytherapy.
'I jumped at the
chance,' says Margaret. 'My attitude is that if you get the opportunity of a
potential remedy, you take it. I went straight ahead and signed the consent
forms.'
After the procedure, in May 2007, Margaret could see perfectly straight away, and within weeks she was back behind the wheel. She says: 'I suffered no pain. It was such a relief to get my independence back.'
