As noted elsewhere on these pages:
(http://www.joansbackbonedisaster.com/2021/08/whipsawed-between-two-specialists.html). Because of what turned out to be a flood of dangerously inaccurate information that I was given by an eye specialist, I was concerned about the relationship between osteoporosis drugs (especially Prolia, which I am on) and the macular degeneration, an eye condition now being treated by a retinal specialist.
A brief search turned up articles about relationships between Prolia and macular degeneration, and other osteoporosis drugs (bisphosphonates) in this context as well.

and an article about an upcoming NIH study
Prolia and Macular degeneration - a phase IV clinical study of FDA data

This article looks at relationships between Pfizer BioNTech COVID Vaccine and Macular Degeneration:

Mainly I learned that macular degeneration is related to osteoporosis itself, rather than to drugs (such as Prolia) used to treat osteoporosis (as this retinal specialist had told me).
But I still searched the medical literature as well as I could to see if Prolia itself was threatening my eyesight. There was not much information specifically raising this point. I could not find much.

This article also appears in another journal, Investigative Ophthalmology & Visual Science, for August 2018.
Here are the conclusions:
"Conclusions: Our findings suggest that osteoporosis plays a role in AMD development in postmenopausal women.”
Having read this, on Thursday, August 5, 2021 I called Amgen's Prolia hotline: 1-800-772-6436, and asked if they had any information about Prolia and macular degeneration, or retina, or anything related. And said they had nothing. (Sometimes they say they have information but they'll send it to your doctor, but in this case the agent said she could find nothing, Based on prior experience with this hotline perhaps I can believe her.)
I'll keep questioning, and will report on these pages if I learn more.

Back to my own situation (which I also discuss elsewhere in this blog), I suffer to this day from the dangerously erroneous information I received from a doctor -- a retinal specialist -- who told me that my eye condition was "because you are on Prolia." This misinformation, so carelessly delivered, created a flood of serious and painful difficulties for me.
Based on this misinformation from someone who should have known better, and hoping to wean myself off this drug that I believed was threatening my eyesight, I delayed the next Prolia shot, and, as a direct consequence, suffered three painful vertebral fractures, two thoracic, one lumbar.
Vertebral fractures cannot be set. I was given a tight corset to wear and spent the next several months mostly in bed (also not healthy) because standing and walking were so painful. I also got rid of my car as it was dangerously painful to drive.
Today, years later, I am still in a good deal of pain. The fractures have healed, albeit in a crooked way, but the pain is such that I can no longer safely drive a car. I am just grateful that I can sit up now and walk a little without unbearable pain.
The travel and events with friends and family that I had looked forward to are sharply limited because of the pain from these totally unnecessary fractures.
I still don't understand why the retinal specialist who erroneously told me that my macular degeneration was because I was "on Prolia" couldn't have simply answered my question about my macular degeneration by saying: "Because you have osteoporosis."
But this careless and inaccurate remark triggered a flood of events that left me in a lot of pain, rendering normal activity (driving a car, traveling, etc.) impossible.
I only hope others in this retinal doctor's practice are not giving patients this dangerously inaccurate information!
