Did you know that a non-invasive 'retinal scan' can now detect brain disease?

I watched (actually "listened" while in bed) this nearly 3 hour, EXCELLENT YouTube video on "eye health" since I have eye issues.

And I found this related article:

ncbi.nlm.nih.gov/pmc/articl...

"Furthermore, studies in Parkinson disease (PD) models suggest that these retinal changes occur before pathological signs of PD in the CNS are apparent, raising the possibility that this may represent a biomarker of early PD as well as a biomarker of treatment efficacy."

My husband has glaucoma, stable for years, following surgery. He has had PD symptoms for 2-3 years and started L-dopa last November. His eye pressure had begun to go up but rose to alarm status about that time. His ophthalmologist tried 3 different eyedrops an finally referred him to a specialist. These last drops are keeping the pressure down, but it leaves me wondering, can PD raise eye pressure ? I know L-dopa can, but I can find little information on this topic. Was there any mention of this in the video?

the eye doc in the video is superb... I remember something about "eye pressure" but can't recall the details, sorry

What kind of eye issues do you have? I have had nystagmus since birth, and it is getting MUCH worse now since my diagnosis.

[PDWarrior1900 in reply to gomelgo]

i had to look up the definition of that and i'm very sorry you are suffering from it ....

--------------------------

my condition is extremely minor in comparison ...

1) daily, very sporadic and very mild eyelid tremors (either either, upper or lower) .... about 3 years ago they were severe enough for me to see an ophthalmologist -- who dismissed any connection to PD and thought I had "dry eye condition" and gave me drops (which i never took!)

2) "sensation something is in the eye" ... lasts several seconds ... almost always very mild ... but annoying

I recently had a thorough eye checkup (i'm almost 71 years old) and the doc gave me an overall grade of: A-

I still don't need to wear eyeglasses!
