This has been disgracefully overhyped by all the news media that I've seen that have picked it up, often in very similar words, suggesting that the ultimate blame lies with the original press release.
The fact is that the technique hasn't even been *tried* yet on Macular Degeneration, much less been shown to actually work.
All that's been done is some studies on a quite different disease for which quite effective treatments already exist.
The history of efforts to treat Macular Degeneration is full of false hopes, and it is desperately cruel to grieving patients and relatives to put out seriously premature press releases like this. I am an eye surgeon specialising in these conditions and I had to deal with some very upset people because of this only today.
Prof Marshall is a very eminent figure in the development of laser treatments for eye disease, but if he had much to do with the way this has been presented to the media he should do some hard thinking about his responsibilities.
There's a brief press release about this on the website of the Royal College of Ophthalmologists (British eye surgeons' professional organisation)
