What causes Dry Eye Syndrome
There are many causes of dry eyes, but the end result is the same; Either the eyes are not making enough of tears to adequately moisturize and lubricate, or the tears that are being made are of poor quality causing them to evaporate off of the eyes very quickly. both scenarios will result in feeling of dryness. Such causes can be hormonal as with women in menopause or on birth control. People with autoimmune diseases are commonly affected as well. Tear production decreases with age, so it is very typical to experience dryness symptoms as we get older.
Who is at risk for dry eyes?
What are some symptoms of DES?
Excessive tearing – When the eyes become dry they begin to burn. The irritation causes the large tear gland under the lid to respond by producing large amounts of tears onto the surface of the eye. The tearing is in response to irritation and dryness, but unfortunately does not lubricate the eye effectively and can be bothersome with tears running down the cheeks.
What are the treatments for DES?
The primary treatment for dry eyes is the use of artificial tears. Artificial tears must be used at a minimum of 4-6 times per day to feel any relief. Tear drops may be used as frequently as necessary even every half hour when reading or using a computer. You cannot over use artificial tears, they are over-the-counter and very safe. We NEVER recommend the use of visine, murine, or generic brands, as these are not ideal tear preparations. Recommended brands include:
If these brands irritate the eyes there are also many forms of preservative free tears. Ask us if preservative free artificial tears are right for you.
Punctal occlusion – There are tear drainage areas called puncta on both the upper and lower eye lids. Blocking off the drain (or puncta) at the lower lid can increase the duration that one’s own tears or tear supplements (artificial tears) remain on the eye. The drain can be closed temporarily by inserting a plug into the puncta. Plugs can be temporary (collagen and dissolves after three months) or permanent (silicone and does not dissolve).
Restasis – This is the only available prescription medication for dry eyes on the market. It has been shown to reduce the symptoms of dry eye by reducing inflammation on the eye. It has also been shown in some patients to increase the body’s own production of tears. Studies show that it can take upwards of three months to see any benefit from Restasis. If it has not produced a positive response in this time frame, it is usually stopped.
