Ask an Eye Doctor and Get an Answer ASAP
Hi. I'm online and happy to answer your question today. How long do these swirling circles last when she experiences them? I understand that that it occurs multiple times, I was just wondering how long each episode lasts.
It never stops, goes on all day, every day? Can you make sure that is what she means.....
and occurs in all lighting conditions, from inside,dim, outside, sunlight, cloudy etc...
Correct, it never stops. She says when she's outdoors it's less noticeable, but sill occuring.
Ok. One other question. Would you say that in all other respects she is a normal, healthy young girl who has no problems doing anything she wants to do, such as read, run, play video games etc?
Absolutely. Everything else is normal. This just happened to come up in conversation, and I was floored because I wouldn't have known this has always been her view of normal vision.
That is not uncommon. Kids think what they experience is what everyone else sees too.....
Ok. Well, your answers have caused the many bad things that can cause what your daughter is experiencing to move way down on my differential diagnosis list. Of course it would be a lot easier for me to know what the issue is if she was here in my office.
First of all, I agree: She needs a complete eye exam by a pediatric ophthalmologist. But, when it is all said and done I think what she is experiencing is going to turn out to be something called the entoptic phenomena
These are images whose source is actually inside the eye itself. There are different manifestations of entoptical effects, depending on how they are generated. Blue field entoptic phenomenon looks like tiny bright dots, or bugs, moving along a wiggley racetrack. These are easier to see when looking at a uniformly lit area such as the blue sky, an illuminated wall in your home or a field of pure blue light. What you are actually seeing in this case are white blood cells racing through the capillaries in front of the macula, or central part, of your retina.
The Purkinje tree is another example of an entoptic phenomenon. This is an image of your blood vessels, located above the retinal photoreceptors, inside your eye. It is best seen by shining a small bright light against your closed eyelids, against your eyeball, or obliquely through your pupil, and wiggling the light quickly back and forth. You may have experienced this image when being examined by your ophthalmologist with the bright light she has on her head. You don't normally see this image as your retina is adapted to the shadow they cast however, when you shine the light from the side, the adaptation is defeated and you see the vessels.
Here is a good web page that discusses this:
Does this make sense to you?
Yes. Is there a cure for this?
By the way, this issue is way beyond the ability of an optometrist to deal with. I'm glad to hear that he sent you to an ophthalmologist.
There is no cure needed.....is a condition inherent in the physiology,anatomy and biology of the eye and the visual system. Some people notice it and most don't. I've seen mine with a special light. It is kinda neat to know that you are actually looking at your own blood cells live as they move through your retina. :-)
well, she will need glasses for being near sighted. Do you think maybe that would make it a little less noticeable?
Perhaps....or it might just bring them into better focus :)
what is the take home message? 1. Have her see a pediatric ophthalmologist just to make sure everything is OK. 2. Don't worry. I believe everything will be fine.
