Diabetic retinopathy and eye health: What to watch out for

So, my grandma's been dealing with Type 2 diabetes for 25 years now, and she’s headed into the hospital in about two weeks
because her vision is getting pretty bad—it's really starting to worry me. I have a few questions...
Specifically, what's the deal with the FAG testing and photocoagulation? Do they actually put you under with
general anesthesia for those, or is it something else?
Also, what's the point of those eye injections they mentioned? And do those require any kind of
numbing or sedation? (The doctors said she'll need them since her eyes are all swollen up)
And does anyone know how long this hospital stay might actually last? Like, is it something
long-term or just a quick thing?

If anyone knows anything at all, please let me know—I'm honestly spiraling a bit here...😢
Thanks in advance...

Best,

How exactly are FAG testing and photocoagulation performed? Are they done under
anesthesia or what...?
And what is the purpose of those eye injections, and are they administered under any kind of
anesthesia; (we were told she’ll need injections because of the swelling in her eyes)
Also, how long does this hospital stay usually last—is it something
long-term or...?

If anyone knows anything about this, please let me know because I am incredibly worried... 😢
Thanks in advance...

Best,

Since I'm currently studying ophthalmology, I might be able to help you out a bit....
Diabetic retinopathy is a serious complication of diabetes. It shows up as changes in the retina that start with tiny damages to the blood vessels, which eventually expand and lead to the proliferation of blood vessels and connective tissue inside the eye.
This happens either due to high intraocular pressure (glaucoma) or extreme fluctuations in blood sugar levels... hyperglycemia (which is what's happening with your grandmother). This occurs because the eye is extremely sensitive to changes in nutrient supply. If your grandmother has reached the stage where she needs photocoagulation... then we're likely talking about an advanced stage of the disease where the eye itself can't be "cured," but the goal is to stop or at least slow down the progression. When I say progression, I mean the condition of the eye, not the diabetes itself.... Photocoagulation aims to prevent further blood vessel growth in the eye and improve their blood supply. But from what I can see... you can only achieve quality, long-term results if the diabetes itself is managed much better. So, it isn't really a "cure"—since a cure implies recovery—it's more like preventing a greater evil.
Does it hurt? I'm sorry, but I honestly don't know... though I doubt it's painful. It sounds like it would hurt because an injection in the eye seems so brutal.... but a lot of things in medicine seem that way, so it's not the end of the world.
I hope this helps even just a little bit.

First off, thanks for the deep dive 🙂 you really laid it all out for me there. But honestly, I’m still stuck on the whole search process—like, how does that actually go down? And those injections... they're definitely making me a bit nervous. Do they give you anesthesia for those, and what’s the actual point of them anyway?
I'm low-key terrified that my grandma might end up losing her sight... I mean, realistically, how big of a risk is we're talking about here?

Thanks..
