Eye infections caused by parasites

There’s a new contact lens solution scare this week.  Last year it was fungus, this year it’s parasites.  Apparently there has been an increase in amoebic infections in the eyes of those who use a type of moisturizing contact lens solution.  These amoebas are pretty common (and relatively harmless?) in the water supply, but put them in your eyes with a few moisturizing drops and you’ve got yourself a dangerous infection that can even result in blindness.  Scientists are puzzled as to why this mixture might increase the risk for infection – some speculate that the moisturizing chemical sticks to the amoebas and keeps them in the eye (rather than having them drop out in your tears).  But at this point, no one really knows why there have been increased infection rates, or what the contact lens solution has to do with it.

I guess my advice would be – never put tap water in your eyes or on your contact lenses, and switch to a different brand of contact lens solution than Advanced Medical Optics, Inc.’s Complete Moisture Plus until further notice.This post originally appeared on Dr. Val’s blog at

The Spirit Of The Place: Samuel Shem’s New Book May Depress You

When I was in medical school I read Samuel Shem s House Of God as a right of passage. At the time I found it to be a cynical yet eerily accurate portrayal of the underbelly of academic medicine. I gained comfort from its gallows humor and it made me…

Eat To Save Your Life: Another Half-True Diet Book

I am hesitant to review diet books because they are so often a tangled mess of fact and fiction. Teasing out their truth from falsehood is about as exhausting as delousing a long-haired elementary school student. However after being approached by the authors’ PR agency with the promise of a…
