I understand. The first thing we want to be sure when folks have tearing is that they dont have a blockage and it seems you dont. Now, why would using lubricants all day help?? I assume he told you that you have a dry eye syndrome of sorts and lubricants will help. Dry eye is very complex. Lets talk a bit about this now so you know what is happening. You may or may not know, the tears that help lubricate the eye are made of 3 different components. One is the actual watery component made in the lacrimal gland under your brow. It is where the water is made and if you get something in your eye or your eye is irritated, this gland goes in to overdrive and causes tears to be produced excessively. Second, is the mucous component and rarely do patients have a deficiency of this (short of chemical burns to eye, as in lye or acid burns). Third is the oily component of the tears and this comes from the glands at the base of the lashes, called meibomian glands. Those glands are often the culprit in someone with tearing..... folks with meibomian gland dysfunction (which is easily overlooked) have lots of tearing and here is why.
When your hands are dry, you dont put water on them although it makes sense to do so if you think about it in the most basic sense. However, you go get lotion which is oil and water mixed in a precise mixture. Same with your eyes, if you have meibomitis or posterior lid margin disease, oil glands become boggy and they dont drain and it contributes to a tear that is more mucousy, but less oily and the tear evaporates quickly (doc sees a thing called decreased tear breakup time) and the surface of the eye becomes irritated as there is no continuous lubrication. Instead the surface becomes irritated and it causes running of the eyes because the eye things there is something stuck in there, and tries to flush it out. Unfortunately, unless the glands become more functional, the situation never gets better. So the best treatment for this situation is the faithful and consistent application of heat packs which help the oils get moving. We are not talking a warm washcloth, that gets cold quickly, rather a heat pack that applies constant heat for at least 3-5 minutes at a time. If this does not provide good relief, your doc may consider an antibiotic like doxicycline, tetracycline or minocycline for 6-8 weeks or longer. These help the glands drain better. Also, use lubricants as you are doing, and even a nighttime ointment may be used, such as Refresh PM.
Take care and let me know if there is any more questions or concerns.
