Medical Forum / General / Vision / February 2008Scintillating scotoma
I've had these occasionally over the past decade without problem, sparkling zig zag lines that start somewhere towards the middle of my visual field and gradually move to the edges, then disappear. More recently, over several months, I have a rather different in nature, semi-permanant scintillating scotoma, reoccurring every few days, sometimes staying for hours. It is different in that it is small and oval shaped, about 3 x the diameter of a letter 'O' at normal viewing distance. It seems to be getting more persistant. Should I be concerned about it? Is there any appropriate treatment/remedy, or will an opthalmologist tell me to ignore it and hope for the best?

Thanks, I'll look into that. Will discuss it with my GP tony > I've had these occasionally over the past decade without problem, > sparkling zig zag lines that start somewhere towards the middle of my > visual field and gradually move to the edges, then disappear. The prime features are that the arcs seldom or never cross the midline, and they occur in both eyes simultaneously. That's neurological, not in the eyes. > More recently, over several months, I have a rather different in > nature, semi-permanant scintillating scotoma, reoccurring every few [quoted text clipped - 3 lines] > be concerned about it?

It's generally harmless, but get a dilated eye examination to check for vitreous traction. -MT, OD > More recently, over several months, I have a rather different in > nature, semi-permanant scintillating scotoma, reoccurring every few [quoted text clipped - 3 lines] > be concerned about it?

And at 22 inches, (normal viewing distance" yields an angle of 0.17 degrees. And 3 times that is 0.42 degrees, well within the macula. I don't think vitreous traction shows up in a dimension that small. (Mine didn't). Besides you would see retinal "flashes" if traction exists from time to time. I would suggest skipping all of the intermediate doctors and go to an ophthalmologist for an exam of that area. Don W. |
