I wouldn't think there would be really any correlation..she is a white dog. But then again, I haven't looked that closely at dog's eyelashes.
I know people with white eyelashes generally have albinism. People with albinism obviously are prone to sun burning..I'm not sure about deafness or blindness, but I don't think so.
From what I can tell, Po should be fine. She has black pigment and everything. If she didn't have the black pigment I may be a bit concerned about possible deafness but honestly I highly doubt it.
