It's never a good idea to make a change based on ONE night's data. It's possible that 3/14 was just a BAD night. And strictly speaking, the AHI was acceptable on that night and as ragged as your flow limitation graph is, I've seen worse.
In fact that, in terms of events including RERAs, Saturday night was probably my worst night since starting Cpap and I was so tired all day yesterday. It's got me wondering if I should have just stayed at 8 at the start instead of wanting to make things "better"...because now I can't go back to 8. Last night the machine was set back to 7-10 and tan is right, the pressure really wants to go higher than 10.
As I said before: It could be that Saturday night was a random "bad night". Most of us have them occasionally. (I had one last night myself.) Most of the time there's no particular, identifiable reason for an occasional bad night. They just happen. And if you just leave the settings be, the next night things go back to "normal". I still think given the eye problems it would be useful for you to go back to straight CPAP at 8cm for 5-7 days
regardless of what the data looks like the first day or two looks like. That's the only way to see if your sleep can stabilize to what it was looking like before you switched to APAP in an effort to reduce the flow limitations. That's also the only way to see if your eyes do better at a lower pressure than the APAP range you're currently using.
When you are using APAP, what's driving the pressure up is flow limitations and not apneas/hypopneas. In other words, strictly speaking, it's questionable whether adding the additional pressure to smooth out the flow limitation curve is giving you any real benefit----particularly since it comes at a pretty significant "cost" in terms of your eyes.
I would love to try 9-11 or 12. But the eyes.
Why do you want to try 9-11? What do you think you would
gain from increasing the pressure range? We know what you lose: The eyes will be even more unhappy at 9-11 than they are now.
I have not finished at-home experiments. Last night I did not put ointment in my eyes and I did not put any (hypoallergenic) skin cream around them, just plain washed skin and some artificial tears. When I woke up, my lids were half gummed shut which scared me, but the eyeballs themselves weren't quite as inflamed and they recovered more quickly. So: hmm. Maybe the petroleum/mineral oil ointment isn't actually good.
The petroleum/mineral oil ointment isn't particularly good for your mask either. But having the eye lids half-gummed shut is not acceptable either.
My advice remains: Go back to straight CPAP at 8cm for a week or so and quit worrying about the dang flow limitations graph OR your AHI as long as it's below 5.0. Get the eyes back to feeling at least "ok" first. Then worry about what you can and cannot do in terms of CPAP settings and how they affect the eyes.
I have mask liners coming in today's mail which I have never used before, so tonight I am going to use one with my mask. I feel like the Pico mask is not leaking, but it can have small leaks if moved too much while side sleeping and for all I know while I'm more deeply asleep I may be shoving the mask out of place and just enough air is coming out to hit the eyes (the leak graph supports this hypothesis). I also want to experiment with using the goggles and no eye ointment. I want to have gone down a list of all possible variables I can control before I have a doctor telling me I need some procedure.
Do all this stuff at your original CPAP prescription of straight 8cm of CPAP pressure.

What exactly do you hope to accomplish?
- Live longer

- Feel better
Do you think AHI 0.0 will accomplish that goal(s)?
I'll ask you the same questions relevant to your efforts to reduce your Flow Limitations.
