What (Really) Goes Into Treating Dry Eye? A Quick Guide To Dry Eye Symptoms and Treatment.
Dry eye is a condition in which a person doesn’t have enough quality tears to lubricate and nourish the eye. Tears are necessary for maintaining the health of the front surface of the eye and for providing clear vision. Sometimes dry eyes can occur as inflammatory flares with or without systemic involvement like asthma, rheumatoid arthritis, Sjogren’s syndrome, ulcerative colitis, Crohn’s disease, thyroid eye disease, ankylosing spondylitis and atopic dermatitis. Boerne vision center will be happy to communicate findings with your primary care doctor or specialist if we suspect these findings.
Dry eye is a common and often chronic problem, particularly in older adults. With each blink of the eyelids, tears spread across the front surface of the eye, known as the cornea. Tears provide lubrication, reduce the risk of eye infection, wash away foreign matter in the eye and keep the surface of the eyes smooth and clear. Excess tears in the eyes flow into small drainage ducts in the inner corners of the eyelids, which drain into the back of the nose. Dry eyes can also occur when tear production and drainage is not in balance.
What are the causes of stinging, burning or scratchy sensation in your eyes?
Causes & risk factors
Dry eyes can occur when tear production and drainage are not in balance. People with dry eyes either do not produce enough tears or their tears are of a poor quality:
- Inadequate amount of tears. Tears are produced by several glands in and around the eyelids. Tear production tends to diminish with age, with various medical conditions or as a side effect of certain medicines. Environmental conditions, such as wind and dry climates, can also decrease tear volume due to increased tear evaporation. When the normal amount of tear production decreases or tears evaporate too quickly from the eyes, symptoms of dry eye can develop.
- Poor quality of tears. Tears are made up of three layers: oil, water, and mucus. Each component protects and nourishes the front surface of the eye. A smooth oil layer helps prevent evaporation of the water layer, while the mucin layer spreads the tears evenly over the surface of the eye. If the tears evaporate too quickly or do not spread evenly over the cornea due to deficiencies with any of the three tear layers, dry eye symptoms can develop.
- Meibomian Gland Dysfunction. MGD occurs when there is a compromise to the function and/or structure of the meibomian glands in the eyelids that produce the protective oily layer of the tear film. These glands can become blocked over time and can no longer produce oils needed for healthy tears. This blockage results in rapid evaporation of your tears and can lead to irritation, discomfort and if not treated, gland dropout.
Dry eyes can develop for many reasons, including:
- Age. Dry eyes are a part of the natural aging process. The majority of people over age 65 experience some symptoms of dry eyes.
- Gender. Women are more likely to develop dry eyes due to hormonal changes caused by pregnancy, the use of oral contraceptives and menopause.
- Medications. Certain medicines, including antihistamines, decongestants, blood pressure medications, and antidepressants, can reduce tear production.
- Medical conditions. People with rheumatoid arthritis, diabetes, and thyroid problems are more likely to have symptoms of dry eyes. Also, problems with inflammation of the eyelids (blepharitis), inflammation of the surfaces of the eye, or the inward or outward turning of eyelids can cause dry eyes to develop.
- Environmental conditions. Exposure to smoke, wind and dry climates can increase tear evaporation resulting in dry eye symptoms. Failure to blink regularly, such as when staring at a computer screen for long periods of time, can also contribute to drying of the eyes.
- Other factors. Long-term use of contact lenses can be a factor in the development of dry eyes. Refractive eye surgeries, such as LASIK, can decrease tear production and contribute to dry eyes.
- Advanced dry eyes may damage the front surface of the eye and impair vision.
What are the causes of stinging, burning or scratchy sensation in your eyes?
People with dry eyes may experience irritated, stinging, gritty, scratchy or burning eyes; a feeling of something in their eyes; excess watering; and blurred vision. Symptoms include:
stinging, scratching, or burning sensations.
Stringy mucus near the eye.
Dry eyes can be diagnosed through a comprehensive eye examination. The doctors at Boerne Vision Center can also grade the severity of the dry eyes and discuss treatment options in detail. The doctors will also make sure that it is actually dry eyes causing the stinging, burning or scratchy sensation in your eyes, sometimes there may be debris, eyelash, or foreign body inside the eye, if so, the doctors can help remove that. Some people’s eyes are dry because they sleep with their eyes open or their eyelids are not shutting properly between blinks.
Dry eye testing with emphasis on the evaluation of the quantity and quality of tears produced by the eyes may include:
Patient history to determine the patient’s symptoms and to note any general health problems, medications or environmental factors that may be contributing to the dry eye problem.
External examination of the eye, including lid structure and blink dynamics.
Evaluation of the eyelids and cornea using bright light and magnification.
Measurement of the quantity and quality of tears for any abnormalities. Special dyes may be put in the eyes to better observe tear flow and to highlight any changes to the outer surface of the eye caused by insufficient tears.
Depending on the diagnosis there treatment options can range from over-the-counter drops, prescriptions strength drops, bandage contact lens, ointments, punctual occlusion, or even surgery evaluations.
Home treatment options for stinging, burning or scratchy sensation in your eyes.
Treatments for dry eyes aim to restore or maintain the normal amount of tears in the eye to minimize dryness and related discomfort and to maintain eye health. Dry eyes can be a chronic condition, but a doctor of optometry can prescribe treatment to keep your eyes healthy and comfortable and to prevent your vision from being affected. The primary approaches used to manage and treat dry eyes include adding tears using over-the-counter artificial tear solutions, conserving tears, increasing tear production, and treating the inflammation of the eyelids or eye surface that contributes to the dry eyes.
- Adding tears. Mild cases of dry eyes can often be managed using over-the-counter artificial tear solutions. These can be used as often as needed to supplement natural tear production. Preservative-free artificial tear solutions are recommended because they contain fewer additives, which can further irritate the eyes. People with dry eyes that don’t respond to artificial tears alone will need to take additional steps to treat their dry eyes.
- Conserving tears. Keeping natural tears in the eyes longer can reduce the symptoms of dry eyes. This can be done by blocking the tear ducts through which the tears normally drain. The tear ducts can be blocked with tiny silicone or gel-like plugs that can be removed if needed. Or a surgical procedure can permanently close the tear ducts. In either case, the goal is to keep the available tears in the eye longer to reduce problems related to dry eyes.
- Increasing tear production or reducing ocular inflammation. A doctor of optometry can prescribe eye drops that increase tear production, reduce ocular inflammation, or. Taking an omega-3 fatty acid nutritional supplement may also help.
- Treating the contributing eyelid or ocular surface inflammation. The eye doctor of might recommend prescription eye drops or ointments, warm compresses and lid massage, or eyelid cleaners to help decrease inflammation around the surface of the eyes. You may have heard of Restasis, Xiidra, Cequa or Eysuvis.
- Treating MGD with Manual Expression or Mechanical Expression (LipiFlow). The doctors may numb the eyelids and perform manual expression of the eye glands. While there are multiple choices available for treating MGD, LipiFlow is the only FDA-cleared device for removing gland blockages and restoring gland function. Through advances in the application of Vectored Thermal Pulsation (VTPTM) technology, the LipiFlow treatment utilizes a patented algorithm of heat applied to the inner eyelids and massage to remove the obstructions in your meibomian glands.
The importance of compliance with doctor's instructions
Dr. Johnson also suffers from severe dry eyes and there are roughly 30 million people in the United States and over 300 million worldwide who have been diagnosed with dry eyes.
The doctors at Boerne Vision Center may recommend starting a home treatment in order to treat your dry eyes. The instructions may look something like this:
The doctor would like you to start this daily regimen:
STEP ONE: Wash hands. Take a HOT washcloth or hot compress (Bruder Mask) and hold it directly on your closed eyelids for 1-3 minutes.
STEP TWO: Use Ocusoft foam or lid cleaning wipes to gently clean the closed eyelids. Use side-to-side motion at least 10-20 times on the top and bottom lid margins with clean fingers, cotton-tip, or wipes.
STEP THREE: Use gentle vertical motion massage, from top to bottom on the top eyelids and from bottom to top on the bottom lids to express your natural eye oils.
STEP FOUR: Put one drop of artificial tear after regimen and throughout the day:
x Retaine MGD ☐ Systane Balance ☐ Refresh Optive
☐ 2 times a day x 3 times a day ☐ 4 times a day
Most have learned to live with eye discomfort and have become dependent on drops or other treatment methods that only offer temporary relief. If the over-the-counter and home treatment options are not working, it is important to return to your follow-up appointment to see if there is something else going on. The doctor may also prescribe dry eye medications like Restasis, Cequa, Xiidra, Eyesuvis, etc.
Follow up appointments with your doctor
