Causes and Symptoms of Dry Eyes
Dry eyes are typically caused by decreased tear production, increased tear evaporation or an imbalance in tear composition. Basically, dry eyes are due to inadequate tears. If dry eyes are caused by decreased tear production, it’s usually due to age, medical conditions like diabetes, tear gland damage or laser eye surgery. Increased tear evaporation may be due to blinking less often, eyelid problems or dry air.
Tears are comprised of water, oil and mucus. Small eye glands that are clocked can cause a problem with these components and result in dry eyes. Blocked Meibomian glands are much more common with people who have skin disorders.
The symptoms of dry eyes include a scratchy sensation in the eyes, sensitivity to light, blurred vision and difficulty wearing contact lenses. It can be extremely annoying.
Dry Eyes Treatment
There are a number of dry eye treatments. The most common treatment is artificial tear drops or ointments. Sometimes, this type of treatment works for chronic dry eye. However, your eye doctor may opt to close the duct that drains tears. A temporary or permanent plug may be used. Temporary plugs tend to dissolve over time.
Another option is to perform a procedure called cautery. A special tool is used to burn and close the opening shut. This actually increases the tear level. A medical device may also be used to unclog blocked glands on the eyelids.
