NOTE: Any words here that are URL linked, I'd recommend you read the articles. They'll help you visualise, and hopefully identify if you have any of the mentioned problems. This is a long post so please read on, it's a personal matter and if I can help anyone else understand what it is they suffer from, then great.

 

---------

* Closed Eye Hallucination doesn't really relate to this too much, but includes some good images on what the main symptoms can look like, as well as detailed descriptions.

SUFFERER'S FORUM Bags of information and accounts there.

Palinopsia

Visual Snow

Phosphene

Closed Eye Hallucination

Floaters

 

----------

 

I suffer from a variety of strange visual anomalies. In my childhood I thought it was a normal part of eyesight but after it got worse about a year ago (related to a rush of blood), I've spoken around a bit about it and discovered at least two other people in my year group also suffer from similar/identical symptoms. To find out that this apparently rare set of conditions is more common and misunderstood than I previously thought spurred me to action. So I'm writing this wall of text now for one main reason - does anyone here suffer from this? The lack of understanding of it's causes/root is both stunning and a shame, especially for those whose struggles with this are worse than mine.

 

---------

 

When you look at a source of strong light (directly at a light bulb for example) after-images remain in your vision. When one suffers from Palinopsia these images remain strongly in view for much longer than usual, even if the eyes are closed. For some sufferers it is debilitating in day to day life and in extreme cases can cause depression. This (and many other Neuro-ophthalmological phenomena which I'll give a summary of) are very, very, very badly understood by the medical community. I really can't stress that enough - I've been to doctors before and not a single one knows what this is. The same with others that I know. No ideas about what it is. Or what causes it. And I have proven 20/20 vision to boot.

 

Apart from Palinopsia, I also suffer from Visual Snow and occasional Phosphenes. These usually manifest in the dark, or when I've just woken up. This can be down to mental state and also to sudden changes in light. Also if I'm fatigued or after exercise (long running or a sprint) there effects are magnified hugely. Even when I was younger, if I stared at a constant point of blank colour i.e white wall, my vision would flash darker and lighter, occasionally giving everything a purple/green hue. (Oh God, purple. How that colour follows me around sometimes haha).

 

In other cases I can get small, sharp dots of colour or flashes of small light. These are usually seen when looking at something for a while (a common example is when doing work in an exercise book at school) or if the lighting is harsh or at an angle. This myriad of symptoms are in no way uniform - frequently they are experienced separately or altogether, and some people who suffer much worse than I do have even more serious, almost blinding visual disturbances.

 

I also get visual 'floaters', which are also stronger than they used to be in younger life.

Evidence somewhat links all these visual problems to tinnitus, as well as in some people migraines. I could write even more, but the links above explore quite accessibly for anyone interested the main problems involved. By no means at all am I at the sh*t end of the scale; I can't begin to relate to you some of the horror stories others have reported. Just try and put yourself in there shoes - this sh*t never goes away, eyes closed it's still there.

 

-----------

 

Now the main purpose of the post. In experience I've found that if 2 people in my year alone suffer, then it must be more common than previously thought. So I ask this; anyone who has read this, does it ring any bells? Could you be a sufferer too?

 

-----------

 

tl;dr? I've got a previously thought 'rare' visual condition which is unknown to most doctors, and I've reason to believe more people may also suffer from it. If you think you do in any way, please post about your experiences or anything that may help others. If you don't want to trawl through a wall of text, check the links at the top. icon14.gif

I get quite prominent floaters, and patterns of light do tend to linger but nothing out of what I understand to be the ordinary. My floaters tend to look like amoebas and can really annoy me sometimes. Every direction I look they seem to dart out of the way of my line of vision so I can just see them. It's crap that it can affect so many people and in so many ways, but at least you've found others that suffer and can relate. smile.gif

 

Quite unrelated, but also quite a curious condition, but who here has heard of synesthesia? It's a condition that essentially means that you can see colours in a different way than usual when hearing music or engaging with other senses. Quite odd.

I don't have time to read the whole topic but I'm so glad you posted this as I checked out floaters and I used to get them a lot. (waits for toilet joke). I used to notice it a lot when I went sailing. Against the commonly grey sky I'd notice them. They'd seem to fall down and if I looked up, with a delay, they'd rise again before starting to drop. I remember them very well and I'd like to draw a picture of what they're like but it was great to see the image on Wiki.

I think most of the world population get floaters, right? I know I get them quite frequently, most notably at night or in situations where the room is dark. I used to get them more as a child, but as I grow older I'm starting to not notice them as much.

 

Apparently they are 'remnants of embryonic structures in the vitreous humour', which is interesting.

I get floaters every now and then, though I think it's been a while since I've seen one. I can never look directly at them, if I try to they just drift down then when I look away they rise back to the center. They usually don't persist long. I've also had closed eye hallucination a couple times, always brought on by some kind of drug, though. The most disheartening time was when I had possibly the worst hangover of my life and upon trying to sleep that night I realized that when I closed my eyes I could still see my room around me. I could move my hand or an object in front of my closed eyes and see it as though my eyes were open. Made sleeping that night difficult, to say the least.

Wow, I started seeing floaters as soon as I started reading that article. weeeird

I also see visual snow too, but only in the dark

 

Never had a CEH before except for when I push my hands in my closed eyelid

I get all that stuff and more.

 

I have some pretty f*cked up eyes. I have a bad astigmatism from birth - doctors surmise that use of forceps (an outdated practice) may have contributed. I grew up fine, with this problem flying under the radar (but in retrospect caused some difficulties) but when you're born with severely bad vision in one eye, the brain doesn't develop properly. It recognizes that one eye doesn't work, and essentially "shuts it off" or simply learns to ignore visual data received by that eye that conflicts with the good eye.

 

In one sense, this is a good thing - combining the data of one good eye and one bad eye can reduce vision overall. But it's killer for depth perception.

 

So, I was just young enough to treat it by wearing a patch over my good eye. This was hell. It was going from 20/15 vision (the typical, above average eyesight of a kid) to 20/500.

 

After treating for a while, my eyeball slowly "turned on". Now, it's certainly not perfect. But like you, I've got fantastic vision in one of my eyes, and I experience a huge variety of visual anomalies. A lot of it is due to the wonky wiring in my brain that came from growing up with one sh*tty eye.

 

It is all normal stuff, however. Many people's eyes just function differently. I can't enjoy a DLP, for example, because every time I move my eyes, the rainbow trails are super obnoxious. In low light, digital displays seem to "float". I see lots of crazy sh*t in low light.

 

One of the weirdest things is that my bad eye is a slightly different color temperature. It's pretty trippy. Really plays into that whole philosophical standby "do different people see different colors than me?" Well, yeah. I see different colors depending what eye I'm looking out of. this is another of those things most notable in low light.

 

The "flash" effect has always plagued me. It's gotten far better with age, but even now, a strong camera flash will f*ck me up for a few minutes. And I have a lot of difficulty going from bright light to dark areas - and it's not that my eyes are slow to adjust - it's my f*cking brain, man!

 

Life is f*cked up sometimes.

I got a little bit all of that, but I don't find it bothering, except maybe if I'd look at light bulb but why would I do that

Arggh, tell me about it! A mobile phone screen in summer can reflect a beam and then bam! - a good few minutes of after-image.

 

I think your story of your life with a bad eye is interesting to note, how the eye itself affected the brains functioning and workings. I mean it seems that brains inner, especially visual functions are open to getting f*cked up from just about any stimuli (your eye problem, circulation problems, migraine, aneurysm etc.) It's just so delicate in there. That delicacy and difficulty of 'testing' is what has hindered research into this so much.

I seem to have a little bit of everything up there. The most prominent is my problem with bright lights. It's not so bad when the rest of the area is lit up, but when it's darker, and there's a bright light (my laptop screen for example), it can really f*ck up my eyes for a good thirty minutes. It sometimes can make me feel nauseous, as well. I also have trouble adjusting to changes in light. It seems to take forever.

 

The Visual Snow is something else that annoys me. The slightest difference in light can trigger it, and it gets even worse at the edges of my vision. If I close my eyes, it looks like dead air on the TV sometimes. I've also had experiences with the floaters, though it's not as frequent. Although there is this black dot that's always in my vision. It's been there for as long as I can remember, and I have no idea what it is.

I do think it's a little bit due to, uh, simply being aware of it. You know? How often do people close their eyes and take note of what they see? Willing to be most folks don't.

 

It's a little bit obsessive. And it's the sort of thing that gets worse when you do notice it. As soon as you take a moment to close your eyes and take note of, say, any light trails - they'll plague you for like 10 times as long. A feedback loop of sorts.

 

If you're easily bothered by this sort of thing, like me, you're probably also easily bothered by other menial things that people take for granted. Like swallowing. (No, just normal swallowing, children) If I think about swallowing, I have to do it obsessively. And then it becomes difficult. And nothings worse than trying to swallow and not being able to... mentally, it's like choking. wink.gif

 

Or getting your toe bunched up in your sock in your shoe. If you take note of that, it'll eat at you and drive you f*cking nuts until your tear your shoe off and fix your sock.

 

Just a little bit of healthy OCD. Right? Totally healthy, right?

I have very bad visual snow, to the point where I can't make out stars in the night's sky, and looking at the wall regardless of what the lighting conditions are just produces visual snow effects.

 

This sums up what I see 70% of the time:

Since age 3 I occasionally see floaters but only when looking directly at blue sky, and I can never look at them directly. They always glide down as I look down.

Visual snow in daylight is horrible, I don't get it much at all but as I said after waking it is annoying enough. I can't believe how bad it would be to permanently stuck with it. And your after-images are a lot worse than mine. agent, have you considered browsing the sufferers forum? Anyone else that has this for that matter, give it a look over. It has tons of things which relate to anyone with this, like some possible remedies, experiences with medication etc.

 

Also floaters are a normal occurrence, so all you guys posting about that only don't worry - it's a regular thing to experience. However, if it's a massive amount of them swarming around combined with the other symptoms then you're probably closer to actually having a problem.

 

*has anyone here experienced blood vessel like light patterns when eyes are closed? It's like there's some fluorescent liquid in the veins beyond my eye, and I can see it when closed. It's strange and sometimes I see it when I cough, sneeze etc.

Palinopsia (Greek: palin for "again" and opsia for "seeing") is a visual disturbance that causes images to persist to some extent even after their corresponding stimulus has left. These images are known as afterimages and occur in persons with normal vision. However, a person with palinopsia experiences them to a significantly greater degree, to the point where they become difficult or impossible to ignore. This often results in mild to severe anxiety and/or depression. Palinopsia sometimes appears on its own, but is more often accompanied by other visual disturbances such as visual snow, and can be attributed to a number of conditions affecting the brain including, but not limited to, medications, seizure disorders, tumors, occiptal lobe or visual pathway lesions, subcortical hemorrhage, and dural arteriovenous malformations

I have all these issues. I first developed visual snow after receiving chemo and radiation for a brain tumor when I was 7, and have had to live with it ever since (37 now, and cancer free). It’s especially worse against a solid background like a wall or a blue or night sky, and when I shut my eyes. I can only see stars using my peripheral vision because it’s impossible to focus on one with all these dots of light in my vision. Whoever I try, the star just becomes another point of light in the billions of tiny dots I see. Sometime after that (don’t remember when), I became aware that I had tinnitus, which I recently found was linked to visual snow. Loud noises make it worse, and it never ever goes away. I get afterimages a lot too, which makes driving in the dark a nightmare, especially in the city. The bright lights from street lights and headlights against a dark landscape make it impossible to see anything else because my eyes are too slow to adjust. Just recently, I think I developed palinopsia, because yesterday I noticed there was an afterimage in my left eye that wouldn’t go away. The odd thing is there was no stimuli for it, no bright light that caused it, and no migraine or nausea. It still persists, and I’m wondering it it could be a more serious condition. Will see the eye doctor this week.

The truth is that most doctors don't understand common disorders such as depression and anxiety. In fact, much of the medical community still doesn't understand the difference between depression and grief, the former being a central nervous system disorder, and the latter being an emotion.
