This is a special circumstance, one that won't be fixed by radio shack. But there is technology available that emits low level infrared light to detect eye motion and blinking. I can almost guarantee there is a device specifically for this purpose; detecting and translating specific eye movements to set pre-programmed phrases. This can be a voice, typed words, whatever. These tools are valuble not only on a safety level but can be psycologically comforting by increasing the persons ability to communicate. Now, I can't say this is cheap, but there are options available for people in dire situations. With some research, you should be able to figure something out that will help even if the degenration reaches her finger and hand movement.
