Ed - My vision changed too almost immediately. 6 months later (at age 52) I suddenly needed cataract surgery, not a gradual progression to it (both eyes. not just left). My vision had become blurry as well, but mostly because they became so dang dry! They're still very abnormally dry. I know you once suggested Sjogren's, but my last Neurologist said No - since we already knew my Idiopathic PN was axonal sensory whatever that it can't be Sjogren's. He blames the dry eyes and my dry mouth I have it on the radiation I received, though that timing is definitely not right because my radiation came 4 years after the dryness and start of PN. My eye doc did think the eye dryness "could" be due to PN but also said that some folks (of all ages) just have more trouble than others.
