What is macular degeneration?

I can't give you an exact chance really. This problem of neovascular degeneration of the retina, which is a devastating cause of visual loss is due, we think, to some sort of metabolic fault in the retina. This allows blood vessels to grow into the retina and then distort the retina. Up until very recently we haven't had very good treatment for it, because lasers can be quite destructive. If you laser a retina, you destroy the retina in the process. But there are some very exciting developments because there are now two new drugs that seem to be helpful in this condition. So it's possible that in the future we may be able to treat people like you with this condition.
