Dry eye: symptoms, causes, and treatment

Dry eye is a common condition that occurs when tears are not able to provide adequate lubrication to the eye. This could be due to insufficient tear production or rapid evaporation of tears. This condition may cause discomfort and irritation, and in some cases it may affect vision

Symptoms
– Burning or itching in the eye: a constant burning or itching feeling.
– Eye redness: due to irritation.
– A feeling of the presence of a foreign body: a feeling of the presence of sand or a foreign body in the eye.
– Blurred vision: Vision may be affected, especially after reading or using the computer.
– Mucous secretions: around the eyes.
– Sensitivity to light: Difficulty looking at bright light.

 Reasons
– Decreased tear production: It may be caused by aging, certain medical conditions such as rheumatoid arthritis, or the use of certain medications.
– Increased evaporation of tears: As a result of dry weather, wind, or smoke.
– An imbalance in the components of tears: Changes in the composition of tears can affect their effectiveness in moisturizing.

 Risk factors
– the age: Older people are more susceptible.
– Use of electronic screens: Prolonged use of digital devices.
– Hormonal changes: Especially in women.
– Ocular surgery: Like LASIK.

Diagnosis
Dry eye is diagnosed through a comprehensive medical examination that may include:
– Schirmer test: to measure tear production.
– Eye dyes: to detect damage to the surface of the eye.
– Tear quality test: to measure the evaporation rate of tears.

Methods For Treating Dry Eyes:

1. Artificial tears
These drops moisturize the eyes and compensate for the lack of natural tear production. There are different types, some of which contain preservatives and some do not, and it is preferable to use preservative-free types to avoid irritation.

 2. Medicines
– *Anti-inflammatories: such as drops containing cyclosporine, which help reduce inflammation in the eye and increase tear production.

 3. Blocking the tear ducts
A medical procedure that involves the use of small plugs placed in the tear ducts to reduce tear drainage and increase their retention on the surface of the eye

 4. Intense pulsed phototherapy (IPL)
It is used to stimulate the meibomian glands in the eyelids to improve the secretion of tear oil, which helps reduce tear evaporation

5. Protective glasses
Special glasses help protect the eyes from the wind and reduce tear evaporation. Some types are known as “humidity goggles” or “wet room goggles.”

6. Home remedies and lifestyle changes
– Increase humidity: Use air humidifiers at home.
- Taking omega-3 supplements: They may help improve the quality of tears.

Rest for the eyes: Take regular breaks when using electronic screens.

 7. Warm compresses
Using warm compresses on the eyelids can help unclog clogged sebaceous glands and improve the quality of tears.

 8. Cleaning the eyelids
Gently cleaning the eyelids with diluted baby shampoo or specialized products can help get rid of crusts or oil that may be clogging the meibomian glands.

It is important to consult an ophthalmologist before starting any treatment to determine what is most appropriate for your particular condition.

Prevention
– Comfort for eyes: Take breaks while using screens.
– Suitable environment: Avoid dry and windy places.
– Healthy diet: Includes omega-3 fatty acids.

 Conclusion
Dry eye is a condition that can be uncomfortable but can be managed effectively with proper diagnosis and appropriate treatment. It is important to consult an ophthalmologist when experiencing any of the symptoms to ensure the maintenance of eye and vision health.
