Dr. Dan B. : Hello and thanks for your question. Are you available to chat?
Dr. Dan B. : i can understand thinking that a dry eye is entirely a function of total body water but there is much more involved in it than that, usually. Let me elaborate...
Dr. Dan B. : The most common reason for the eyes to be causing these symptoms is due to a dry eye, also called a dysfunctional tear film syndrome. The front of your eyes has a layer of tears coating it called the tear film (this layer of tears is different from the tears you produce when you cry or have an irritation in your eye). The tear film normally provides a healthy environment for the front of the eye (the cornea and conjunctiva) and also contributes significantly to clear vision. When the tear film is unstable or unhealthy (there are many reasons why this can be so, which I will get to) it becomes dysfunctional and can produce uncomfortable symptoms and blurry vision. This is called a dysfunctional tear film.People with a dysfunctional tear film can have multiple different symptoms ranging from redness, dull aching or pressure, sharp or stabbing pain, morning tearing, burning, and often eyelash mattering to tearing, stinging, itching, burning, a gritty/foreign-body senstation or just intermittent vision fluctuations. Their symptoms sometimes get better as the day progresses or they can often times worsen throughout the day, but they can get intermittent blurring when they use their eyes heavily in activities such as reading, watching TV, computer use or driving. A dysfunctional tear film can be due to many different factors. Different medicines such as psychiatric medicines, antihistamines, cold medicines and others can contribute to a dysfunctional tear film. Allergies in the eyes can also contribute (and or make worse). Some people have an innate deficiency in making their own tears (these people may also have other dry mucus membranes, such as their mouth, nasal passages, or genitalia). Any kind of eye surgery can actually cause and/or worsen this Many people have an inflammation in the eyelids called blepharitis which causes the tear film that is supposed to coat the front of the eye to not function as well, and then the eyes dry out.
Dr. Dan B. : I would recommend using artificial tears 4x/day in both eyes (one drop per application). After 4 weeks you should be able to start tapering off of the tears to as you need them.
Dr. Dan B. : If you are a person that doesn't make their own tears very well, then you may also benefit from taking that Restasis, which actually modulates a person's immune system to help them make more of their own tears. This drop actually requires constant usage on a daily basis for at least 10-12 weeks before its effect kicks in (takes awhile to change the immune response in the body).Because there are numerous reasons for dry eye, if not all the reasons that exist in one patient are treated, it can seem as though the ones that are being treated are providing no benefit. If you've tried these recommendations and still don't feel better then you should consider seeing a corneal specialist for a dry eye evaluation.
