  • There are a number of causes of a sudden loss of vision in one eye. Some occur without pain. Why? What's the anatomy that can allow this to occur?

    I Love the way you present your information. I have a problem with one of my eyes...from 20/20 to suddenly legally blind in that eye and still undiagnosed, even though I have been seeing an Opthamologist for about a year and have had testing at the local hospital. No diagnosis yet...I am now asking to be referred to an Eye Institue with a very good reputation in a city near me.....this is very scary. Anyway, you made this so much easier to understand and I Really appreciate that. Thank You!

      Hi Margaret, did you manage to find out what the exact cause of it was? I've experienced this too during a very stressful period. It passed quickly so I didn't see a doctor, I didn't even knew it was a diagnosis. Diet was pretty balanced but I think my blood pressure was not ok.

    Wonderful explanation - thank you so much Sam!
    I found your video after researching my own experience last week - a bit scary, I must say - of several bouts over a few days of transient, painless, visual loss with no additional symptoms.
    I'm intrigued to hear your thoughts on other causes of transient venous/arterial blockage. In particular, could cranio-cervical instability (I've poor posture from severe pectis excavatum condition) cause grey- or black-out of part of peripheral vision in one eye only for 1-10 minutes at a time and recur several times over a couple of days, due to pinched artery, vein or nerve? I've not experienced before and I'm 56. No history of (painful) migraine; stroke and retinal abnormality ruled out through eye examination; seizure, e.g., occipital epilepsy still to be explored.

    I had an aortic dissection two months ago. I had an aneurysm in my ascending arch that was replaced with a fabric sleeve and a graft on mr femoral artery. When discharged I had several short episodes of vertigo that was explained as possible residual effects from the anesthesia (6.5 hour surgery) or possibly micro emboli going through my blood vessels of my eyes. I was told to see an ophthalmologist and they said there was no evidence of stroke and he said it would have been more concerning if I had lost partial vision in one or both eyes. Well, two weeks ago I lost the bottom half of my vision in only my left eye for 1-2 mins, no other symptoms, it was like a straight horizontal line across the middle and everything below was dark. I called the ophthalmologist back and they told me to come in right then, tests showed nothing different accept because noted something very tiny that he saw the first time and said it’s possible there is a very small arterial occlusion in my left eye and he refereed me to a retinal specialist who looked closer at it and agreed it looked occluded but said that tiny artery would have been responsible for the top part of my vision, not the bottom. They did a dye neon test and it showed that it went through the occluded artery just fine so he said whatever happened is before the eye and said to see my cardiologist. I did and he said it sounds like I had a TIA, made a bunch of orders for different tests and sent me to see a neurologist who then said he’s not convinced it was a TIA, ordered an MRI and said I shouldn’t be too worried about it. The waiting game of these dates is hard thinking about what could happen in that timeframe.

    It happened to me 13 times this year. it only lasted a few minutes ago that it goes black in my left eye. Usually when I have fatigue and also pins and needles in most parts of my body. As well as not been able to move my leg for at least 30 minutes in the morning, and sometimes last an hour, as well as constantly feeling weak. It all seems connected and has been getting worse

  • @jangregory5193
    @jangregory5193 4 місяці тому

    Excellent presentation for a very complex and complicated issue. I'm still struggling to find the actual causative factor... unfortunately it is most likely an occlusion in the retinal artery and there's no real direct treatment

    Been losing peripheral vision in my eyes or sometimes one eye for about 10 to 15 mins at a time for the last year. My doctor seems to think it may be due to micro vascular disease. I'm not even 40 yet I did have a TIA a few years ago in my early 30s that did include visual disturbance. I hade uncontrolled hypertension for many years prior to all of it due to not being able to afford doctor visits. Take care of yourself it's very weird to lose part of you vision. It registers as just parts of things that aren't there part of a word or maybe you stick your hand out and can't see like it isn't there very strange sensation especially when you continue to see everything else. I also get like a rainbow static that takes the place of the missing vision sometimes also very strange. I hope to find a way to heal myself and stop this but micro vascular disease runs in my family.

    I am currently experiencing a list of vision for about 12 days now I have been to the ER where they checked my heart and said it looks good and they did an MRI and didn’t find anything wrong . The next day I went to the opthamologist and he said he doesn’t see anything wrong . And it appears that I my optic nerve is fine . He said that youth is on my side because I am 33 he said he thinks the best thing I can do is give it time . He recommend I got to the neuropathy eye doctor . Do you think I will heal with time ?

    I had a binocular amaurosis fugax that lasted about 10 minutes, I was only 20 years old. My vision was pitch black and slowly came back in the ambulance. Fast forward 35 years and I’m blind in one eye from a retina detachment. Five years later my neurologist said that my brain MRI showed thinning of both optic nerves.
    Ironically I am a retired optician

    My favorite visual disturbance has to be a Posterior Cerebral Artery (PCA) stroke. The defining feature is one-sided hemianopia (half visual field loss) with macular sparing. So much functional anatomy in this one condition. A close second is bitemporal hemianopia.

    I'm 29 now, very fit and relatively healthy, I experienced complete vision loss just 3 months ago, I was after being out the night before but did not drink much, I got up after several hours sleep, after 1 minute I completely lost my vision in both eyes for 20 to 30 seconds, still have no idea what it is, it was almost complete darkness but could not see anything at all, I thought I was going to be blind forever, I was extremely pale when I went out to the kitchen to tell my family, they mentioned, they didn't really know at the time when I said blind I meant completely, they just suspected I meant blurry vision
    Does anyone knows what I should do or what tests exactly to ask my doctor to carry out?
