Do you feel your eyes are unusually dry? Difficulty wearing contact lenses, redness, and a burning sensation in the eyes may be signs that you have dry eye syndrome. This common condition affects millions of people and causes symptoms ranging from mild discomfort to debilitating pain.
In this blog post, we will discuss the causes and treatments of dry eye syndrome to help you identify it and manage its symptoms.
Dry eye syndrome
Dry eye syndrome is a condition in which the eyes do not produce enough tears to keep them lubricated and nourished. Symptoms of dry eye syndrome include dryness, redness, burning, foreign body sensation, blurred vision, and even excessive tearing.
Dry eye syndrome can be caused by environmental factors such as dry climates or air conditioning, certain medications, or age-related factors that decrease tear production. It may also be caused by medical conditions like arthritis or chronic sinusitis.
Treatment for dry eye syndrome includes artificial tears, lubricating gels/ointments, and topical anti-inflammatory therapies. In more severe cases, treatments like punctal plugs or laser therapy may need to be used to help increase tear production.
Who is most affected by dry eye syndrome?
Dry eye syndrome can affect anyone, but certain groups of people are at a higher risk for developing the condition. Some of these groups include:
- Women: Hormonal changes, particularly during menopause, can make women more susceptible to dry eye syndrome.
- People over the age of 50: As people age, their eyes’ ability to produce tears can decrease, making them more prone to dry eyes.
- People with certain medical conditions: People with autoimmune disorders such as Sjogren’s syndrome, lupus, and rheumatoid arthritis are at a higher risk for dry eye syndrome.
- People who take certain medications: Certain medications, such as antihistamines, antidepressants, and blood pressure medications, can cause dryness of the eyes as a side effect.
- People who spend a lot of time using digital devices: Prolonged use of digital devices such as smartphones, tablets, and computers can lead to dry eyes.
- People who have had certain types of eye surgery: Surgery such as LASIK or cataract surgery can increase the risk of dry eye syndrome.
Causes of dry eye syndrome
Dry eye syndrome, also known as keratoconjunctivitis sicca, is caused by a lack of sufficient lubrication and moisture on the surface of the eye. Here are some main causes of dry eye syndrome include:
Decreased tear production: The tear glands may not produce enough tears to keep the eyes lubricated.
Imbalance in the tear composition: The quality of the tears may be affected, leading to an imbalance in the composition of the tear film. It can also disturb mental health.
Evaporation of tears: The tears may evaporate too quickly, leaving the eyes dry.
Blocked oil glands: The oil glands in the eyelids may become blocked, preventing the natural lubrication of the eyes.
Medical conditions: Certain conditions, such as Sjogren’s syndrome, rheumatoid arthritis, and lupus, can lead to dry eyes.
Medications: Some medications, such as antihistamines, decongestants, and blood pressure medications, can also cause dry eyes.
Environmental factors: Prolonged exposure to dry, windy, or air-conditioned environments can lead to dry eyes.
Symptoms of dry eye syndrome
Here are some main symptoms of dry eye syndrome include:
- Itching or burning sensation in the eyes
- Redness of the eyes
- Light sensitivity
- Blurred vision
- A feeling of something in the eye
- Excessive tearing (in some cases)
- Eye fatigue
- Soreness or a gritty texture in the eyes
- Difficulty wearing contact lenses
- Stinging or discomfort during prolonged visual tasks, such as reading or working on a computer.
It’s worth noting that not all people with dry eye syndrome will experience all of these symptoms, and the symptoms can vary in severity. Additionally, some symptoms may be temporarily relieved by artificial tears or other over-the-counter products, but if these symptoms are persistent, it is important to consult an ophthalmologist.
Diagnosis of dry eye syndrome
There are several tests that an eye doctor can use to diagnose dry eye syndrome, including:
1) The Schirmer test
This test measures the number of tears produced by the eyes. The eye doctor will place a small strip of paper under the lower eyelid, which will measure the amount of tears produced in a specific time period.
2) The Fluorescein dye test
This test is used to detect damage to the surface of the eye, such as scratches or abrasions. A dye is placed in the eye, and the eye doctor will use a special light to examine the eye for any damage.
3) The Lissamine green test
This test is similar to the Fluorescein dye test, but it uses a different dye that is better able to detect damage to the surface of the eye that might not be visible with the Fluorescein dye test.
4) The tear film break-up time (TFBUT) test
This test measures how long it takes for the tear film on the surface of the eye to break up. A drop of dye is placed in the eye, and the eye doctor will measure how long it takes for the dye to disappear, which can indicate how stable the tear film is.
5) The Meibomian Gland Evaluator (MGE)
This test measures the quality of the oil component of the tears produced by the Meibomian glands. The MGE uses a special light to examine the eyelids and measure the function of the Meibomian glands.
6) The Osmolarity test
This test measures the salt concentration of the tear film, which can indicate the overall health of the tear film and the severity of dry eye symptoms.
After the tests, your ophthalmologist will evaluate the results and use them to diagnose dry eye syndrome. They may also consider other factors such as your symptoms, medical history, and medications you are taking.
Prevention of dry eye syndrome
There are several steps you can take to help prevent dry eye syndrome or reduce its symptoms:
- Blink frequently: When you’re focusing on a screen or reading, you tend to blink less frequently. It which can lead to dry eyes. Try to remind yourself to blink every so often.
- Use a humidifier: Dry air can exacerbate dry eye symptoms. Using a humidifier in your home or office can add moisture to the air. It can help keep your eyes from drying out.
- Take breaks from screens: Prolonged use of digital devices can lead to dry eyes. Take regular breaks and look away from your screen every 20 minutes.
- Wear sunglasses: Sunglasses can help protect your eyes from the sun’s UV rays, wind, and dry air.
- Eat a healthy diet: Eating a diet rich in omega-3 fatty acids can help improve the quality of your tears. Foods such as fatty fish, flaxseed, and walnuts are good sources of omega-3s.
- Stop smoking: Smoking can worsen dry eye symptoms, so quitting smoking can help prevent and improve dry eye symptoms.
- Consult your ophthalmologist: If you are at a high risk of developing dry eye syndrome or if you are experiencing symptoms, consult your ophthalmologist. They will be able to recommend specific treatments, such as artificial tears or other measures that can help prevent or reduce the symptoms of dry eye syndrome.
Treatment of dry eye syndrome
Treatment for dry eye syndrome will vary depending on the underlying cause and the severity of the condition. Some common treatments include:
Artificial tears: Over-the-counter or prescription eye drops can help lubricate and moisturize the eyes. These drops can temporarily relieve symptoms and are often the first line of treatment.
Warm compresses: Applying a warm compress to the eyes can help to unclog blocked oil glands. It can improve the quality of the tears.
Omega-3 supplements: These supplements can help to improve the quality of the tears. They are available as pills or as a component of a particular food.
Eyelid cleaning: Your ophthalmologist may recommend cleaning your eyelids with mild soap and warm water to remove any debris and bacteria that can irritate them.
Prescription medications: Some prescription medications can help to improve tear production or reduce inflammation.
Punctal plugs: These tiny plugs can place in the tear ducts to help keep the tears on the surface of the eye longer.
Surgery: In some cases, surgery may be necessary to correct a structural problem causing dry eyes.
Lifestyle changes: Some lifestyle changes, such as reducing screen time, avoiding smoke and other irritants, and maintaining a healthy diet. It can help to prevent or reduce the symptoms of dry eye syndrome.
Final thought
As a final thought about dry eye syndrome, we must remember that prevention is the best medicine.
