Patricia d'Happert's vision is so bad she can hardly see the television, much less crochet as she once did. Some people with macular degeneration claim it's a lot like seeing through tunnel vision or with a black hole in their center of vision.
Most doctors say the condition affects overall vision.
For some, like d'Happert, a new, non-surgical technique could help these serious vision problems go away. It all starts with injecting a photosensitive drug into the arm. That then travels up to abnormal blood vessels in the eye. The drug is then activated by a cool laser light. The process destroys the abnomal vessels that cause macular degeneration.
