Re: Fuchs's Cornea Dystrophy QuestionsJohn,
Got your references. Will digest.
I did get a big kick out of "0.0541 logMAR" for being the results of that
one study. I think that is well within the variance of one patient
successively reading the chart.
Lutein is not mentioned. I do know there is some effort to show increases
in macular pigment density by ingestion of this. But.... they don't carry
it forward to show changes in visual acuity, far as I can see (hmmm).
Thanks, good luck to you in everything.
Don W.
PS. Yeah, I do get the freebies of off BJO. Am registered. Nice of them.
