Last time I checked, conjunctivitis is usually viral, and even when bacterial, is a self-limited disease (except if due to STD’s).  Why are so many doctors, even ophthalmologists, still treating this disease, especially with drops like Zymar?! I mean, if you feel compelled to treat, give something like Sulfa or Bacitracin which costs a few pennies. When I see a patient with conjunctivitis, I tell them: “I’m going to give you what I give to my own children!” “What, doctor?” “Nothing!- and I bet you a million dollars you’ll be better in a week or so!” Fee free to use this line on your own patients…
