My wife has age macular degeneration, already lost the central vision in her right eye; been told her left eye has 20/30 vision in her left eye and if she loses vision in her left eye; she will be blind with only peripheral vision in both her eyes. I can't remember where I read this statement, but it said researchers in the UK found that there is a relationship betweeen retinal bleeding and acetaminophen. She is taking Hydrocodone APAP TABS 5/325 W3604 SUBSTITUTED FOR NORCO TABS. I wonder if I should question taking this medicine? I'm reaching for straws to help her out of possible total central vision blindness.
