Dry eye

Dry eye is a medical condition in which the eyes do not receive enough moisture from tears, causing discomfort and sometimes pain. The tears are important for maintaining the health of the eye and its proper functioning, they serve as a moisture substrate, protect against infections and provide nutrients to the cornea. When there is a lack of moisture in the eyes, it can lead to damage to the cornea and conjunctiva, increasing the risk of infections and other vision problems.

The problem of dry eye is very common and it can appear at any age, although it is more common among older people and women, mainly due to hormonal changes that occur during menopause. In addition, people who spend a lot of time in an environment with dry or polluted air, such as air-conditioned offices, airplanes and industrial areas, are more likely to suffer from the symptoms of dry eye.

Symptoms of dry eye include a burning sensation, irritation, sensation of sand or a foreign body in the eye, blurred vision, and eye fatigue. These symptoms can worsen in certain situations such as prolonged reading, prolonged work in front of a computer, or staying in cold and dry weather. In more severe cases, dry eye can cause permanent damage to the cornea and reduce the quality of vision significantly.

Dry eye is not only a physical problem but also a problem that affects the general quality of life. People suffering from dry eye sometimes find it difficult to concentrate on work, studies and other daily activities. The condition can cause a feeling of frustration and chronic fatigue, and lead to sleep disorders and other health problems.

Causes dryness in the eye

Dry eye is caused by a wide variety of factors, some environmental and some physiological and health related. Understanding these factors is important for the prevention and effective treatment of dry eye.

Environmental factors are one of the main causes of dry eye. Prolonged work in front of a computer and digital devices is one of the most common reasons. When we concentrate on screens, we tend to blink less, which leads to increased tear evaporation and decreased eye moisture. Additionally, being in an environment with dry air, such as air-conditioned offices or centrally heated areas, can worsen symptoms.

Physiological factors include hormonal changes, especially in women during menopause, pregnancy and breastfeeding. The hormonal changes affect the production and composition of the tears, which leads to dry eye. Age is also a significant factor, as tear production decreases with age, making symptoms more common in the older population.

Chronic diseases can cause dry eye. Diseases such as diabetes, rheumatoid arthritis and other autoimmune diseases affect the immune and metabolic system, and can cause damage to the tear glands. Certain medical treatments such as anti-allergy drugs, anti-depressants and anti-hypertensive drugs can also cause dry eye as a result of side effects.

In addition to these factors, there are other factors such as prolonged exposure to strong wind or smoke, use of inappropriate contact lenses, and a history of eye surgery. All of these can contribute to the appearance of dryness in the eye and worsen the symptoms.

In conclusion, understanding the causes of dry eye is the key to effective treatment and prevention of symptoms. Early identification of the causes and appropriate treatment can improve the quality of life and prevent long-term damage to the eyes.

Symptoms of dry eye

Dry eye can appear in a wide variety of symptoms, which can be unpleasant and affect the quality of life of the person suffering from the condition. Physical symptoms include a burning sensation and irritation in the eyes, feeling of sand or a foreign body in the eye, red eyes, blurred vision and eye fatigue. The burning sensation and irritation can be continuous or appear intermittently, especially after exposure to environmental factors such as strong wind, smoke or cold and dry weather.

Sometimes, people with dry eye can experience excessive tearing. It sounds paradoxical, but when the eye is dry, it tries to compensate by making more tears. However, the extra tears are usually “reflex” tears that are formed as a response to stimulation and do not contain the necessary ingredients to maintain proper moisture in the eye.

In addition to the physical symptoms, dry eye can affect the overall quality of life. People suffering from the condition sometimes have difficulty concentrating at work, reading, watching TV or performing other daily activities. Symptoms can worsen in the evening after a long day, especially after prolonged work in front of a computer or in places with inappropriate lighting. The persistent feeling of discomfort can lead to general fatigue and a feeling of frustration, and even sleep disturbances if the dryness worsens at night.

Mental and emotional effects are also an integral part of the symptoms of dry eye. People suffering from this chronic condition can feel frustrated and less motivated to perform routine activities. In addition, the constant feeling of discomfort can lead to mental stress and anxiety.

Diagnosis and tests of dry eye

Dry eye diagnosis is usually performed by an ophthalmologist who specializes in eye diseases. The diagnosis begins with a detailed conversation with the patient to understand the medical history and symptoms he is experiencing. It is important to note all the possible factors that can affect the dryness of the eye, such as the use of medications, chronic diseases, working in front of a computer and general lifestyle habits.

The physical examinations begin with a comprehensive eye examination, which includes a visual acuity test and examination of the structure and function of the eye using a microscope. The doctor may use fluorescein staining, a special dye that can be seen under blue light, to detect defects and injuries on the surface of the cornea. This method helps to assess the damage to the surface of the eye and identify places where there is severe dryness.

One of the most common tests for diagnosing dry eye is the Shimmer test. In this test, a small piece of absorbent paper is placed on the lower eyelid for several minutes, in order to measure the amount of tears produced by the eye. The test provides a quantitative measure of the level of moisture in the eye and can indicate abnormal functioning of the lacrimal glands.

Another test is the TBUT test which measures the time required for tears to disperse after blinking. A shorter time than usual indicates dryness in the eye and implies defects in the quality of the tears.

New technologies make it possible to perform a more accurate and detailed diagnosis. For example, osmolarity devices measure the concentration of salts in tears, which can indicate dry eye at a molecular level. There are also devices that record the blink movements and analyze the function of the tear glands, which makes it possible to diagnose problems more accurately.

Through a combination of different diagnostic methods and a comprehensive evaluation of symptoms and medical history, an accurate diagnosis of dry eye can be reached and the most appropriate treatment can be tailored to each patient.

Treatments for dry eye

Dry eye is a condition that can be managed and treated using a variety of methods and treatments, depending on the severity of the condition and the personal factors of each patient. Natural treatments and home methods are the basis for daily management of the condition. Symptoms can be alleviated through lifestyle changes, such as increasing fluid intake, eating foods rich in omega-3s such as fish, flaxseeds, and nuts, and avoiding smoking, which can worsen dry eye. Maintaining a balanced diet and regular physical activity can improve overall health and contribute to eye health.

Warm compresses and gentle massage of the eyelids can help release oil from the meibomian glands in the eyelids, which improves tear quality and reduces dryness. You can use a warm cloth or a heated mask and perform a gentle massage with your fingertips on the eyelids.

Artificial eye drops, also known as artificial tears, are one of the most common and readily available treatments for dry eye. Over-the-counter eye drops can be found in a variety of formulas, including preservative-free for people with hypersensitivity. These drops provide immediate moisture and ease the sensation of irritation and burning. It is important to use the drops according to the doctor’s recommendations or according to the manufacturer’s instructions.

In more severe cases, eye doctors may recommend innovative drugs and treatments. These can include eye drops containing anti-inflammatory ingredients or steroids, which reduce inflammation in the eye and improve tear production. These drugs are usually given under medical supervision to avoid possible side effects.

In cases where the standard treatments do not provide sufficient relief, there are surgical treatments and special procedures. Blocking the tear ducts is a procedure in which small plugs are inserted into the tear ducts to prevent the tears from draining and leave more moisture in the eye. This procedure can be temporary or permanent, depending on the need.

Laser treatment with IPL (Intense Pulsed Light) technology is a relatively new technology used to treat dry eye caused by inflammation of the meibomian glands. This treatment improves the function of the glands and reduces the inflammation in the eyelids.

Prevention of dry eye and regular maintenance

Proper maintenance and prevention of dry eye include adherence to daily habits and maintaining a suitable environment. Maintaining a moist environment is one of the keys to preventing dry eye. Using humidifiers at home and at work can help maintain an adequate level of humidity in the air, especially during periods of artificial heating or cooling. It is important to avoid prolonged exposure to dry air, strong wind or cigarette smoke, which can worsen the dryness in the eye.

When working for a long time in front of a computer or digital devices, it is important to take proactive breaks to allow the eyes to rest and refresh. It is recommended to use the 20-20-20 rule: every 20 minutes look at something 20 feet away for 20 seconds. This action helps to reduce the strain on the eyes and prevent the dryness caused by prolonged exposure to screens.

Using optical aids such as computer glasses with anti-blue radiation coating can ease eye strain. There are also special aids such as protective frames designed to keep the eye moist by preventing excessive evaporation of the tears.

Maintaining eye and eyelid hygiene is an important part of daily maintenance. Gentle cleaning of the eyelids using special wipes or baby shampoo diluted in water can help remove dirt and grease from the meibomian glands, and prevent inflammation and dryness in the eye.

In conclusion, proper management of dry eye requires a combination of daily treatments, ongoing maintenance and maintaining correct habits. A thorough understanding of the causes of dry eye and the adjustment of the correct treatment can significantly improve the quality of life and reduce the symptoms. It is important to consult an ophthalmologist and have medical follow-up to ensure correct and effective treatment.
