Hey, K: It's good to see you. I'm glad you're feeling so much better...and, are still improving.
There are two instances where I have a similar issue with my vision:
1. Before the onset of a migraine. The change in vision is a warning sign for me to get home ASAP, as I lose most of my vision in both eyes, once the migraine is at its worst.
2. When rolling my eyes upward and maintaining an upward gaze. So, imagine standing/sitting in a straight posture with the head looking straight forward and not angled forward/backward and not tilted toward one side or the other. Everything neutral, no limbs crossed, no circulation being restricted. Then, while keeping my head still, I look upward -- holding my eyes at or near the maximum upward angle possible. The "stars" start very slightly and become more dense the longer I hold my gaze. However, if I roll my eyes downward -- releasing the "pressure" and looking forward -- the "stars" vanish and my vision returns to normal. It feels like the extreme upward gaze somehow cuts-off my circulation to my eyes and looking down again allows the circulation to flow again. I've no idea if that's actually what's happening, but it's the only way to closely describe how it feels.
There are two things I've done that you may also wish to consider:
First, I saw an eye doctor. Not an Optometrist, but an
Ophthalmologist. I generally get a yearly exam, though I didn't have one last year, due to being unemployed. So, this is a good reminder for me to schedule an appointment, as I recently got approved for medical and vision coverage.
Second, I had a
Carotid Intima-Media Thickness (CIMT) test, to check the health of my carotid arteries that supply blood to the brain. It's an ultrasound, so it's non-invasive. I was fortunate that my doctor's office had the equipment in-house and my insurance covered the cost of the test. But, I'm not sure how available this procedure might be and/or whether insurance will cover it. The CIMT test
"...provides information about the carotid arteries’ characteristics and may be used for early detection of coronary artery disease as well as cardiovascular and stroke event risk stratifications." SourceBeyond those two things, you could try increasing your hydration, since you mentioned it. Personally, I'm not a believer in drinking beyond my thirst, but that's just my non-medical opinion.
As for circulation, like you mentioned, you could try gentle stretching for your neck/head. If you able, maybe something more full-body to stimulate circulation, such as a rebounder or performing jumping jacks. (I can't do either of these, unfortunately.) Maybe a massage? If not full-body, at least your head, neck, and shoulders. Tell your husband it's for "medical purposes."
Or, maybe a dose of Niacin (Vitamin B3) to cause a "Niacin Flush," if you have no contraindications.
That's about
all that comes to mind, at the moment. I hope you find an easy, safe, and effective solution to this issue. Let us know what you discover.
Best wishes,
Dude
