Medical Forum / General / Vision / March 2005A patch of flickering
At times I see a patch of vision that is flickering, mainly in the left eye but occasionally in the right as well. It is most pronounced when I enter a warm building after being in the cold for awhile. It is only with a specific area with clearly defined borders which seems to be more or less stable in size. I can see through this flicker - which is easiest to discern when looking at a solid, uni-colored surface such as a wall. I asked the eye doctor about it once (not an eye tech, a real opthamologist) and he kind of blew off my question. Any ideas or suggestions? Dear "Errata", I hope this ophthalmologist did a complete retinal exam. Any "flickering" or "point lights" that come and go can indicate an incipient detached retina. If he checked this out -- and explained this to you -- then you are probably O.K. Best, Otis Engineer (I had the same thing -- that is the basis of my suggestion.) >At times I see a patch of vision that is flickering, mainly in the left >eye but occasionally in the right as well.

If just a few seconds, then Otis is on the right track (for once). If it lasts 10-40 minutes or so, then Robert is on the right track. Your description sounds more like ophthalmic migraine to me. If this is the case, you are at *slightly* higer risk of normal-tension glaucoma - but if you've been checked by an eye doctor, there's probably not a lot more you need to worry about. There's no treatment as such. Dom >>At times I see a patch of vision that is flickering, mainly in the left >>eye but occasionally in the right as well.

Usually 5 minutes or so, hard to tell because once I'm not looking at a wall then I no longer see it. Dear Misc Errata, It is always hard to describe these visual experiences. If you are myopic, the probablity of developing a detached retina is much higher -- something to consider. I saw "point lights" flickering -- when I went indoors and looked at blank walls. The effect was more pronounced under mecury-vapor lamps. The effect would go away after about 10 minutes. You might wish to consider a "retinal" exam for your peace of mind. Best, Otis Engineer |
