Great site I will visit again! I have not seen nystagmus associated with macular degeneration in my patients. It seems like it should in advanced cases due to the central blind spot but peripheral fusion cues must keep the eyes on fixation most of the time. I think nystagmus with macular degeneration is usually a coincidence and caused by another problem. There is some evidence that optokinetic nystagmus tests can be altered by certain degrees of macular degeneration, but even that seems to be a very small change. Fortunately, (for me at least) acquired nystagmus is usually something only EMT’s have to make a quick decision on- it’s just too complex and difficult to evaluate without specialized equipment.

Please, don’t forget about BPPV–Benign Paroxysmal Positional Vertigo. It causes nystagmus and can so easily be treated–not serious and all too common. Check out the Dix-Hallpike maneuver.
