Dry eye syndrome

Dry eyeKell

Dry Eye Syndrome (DES), also known as Keratoconjunctivitis Sicca (KCS), is a common eye condition characterized by insufficient lubrication and moisture on the eye's surface. This condition can result from either decreased tear production or increased tear film evaporation, leading to inflammation and damage to the eye's surface.

Causes

Dry Eye Syndrome can be caused by a variety of factors, including:

• Aging: The production of tears decreases with age.
• Environmental factors: Exposure to smoke, dry air, and wind can increase tear evaporation.
• Screen use: Prolonged use of computers, smartphones, and other screens can reduce blinking and increase tear evaporation.
• Medications: Certain medications, including antihistamines, decongestants, and antidepressants, can reduce tear production.
• Medical conditions: Conditions such as Sjögren's Syndrome, rheumatoid arthritis, and collagen vascular diseases can affect tear production.
• Eyelid problems: Issues with eyelid anatomy or function can lead to dry eyes by affecting tear distribution or evaporation.

Symptoms

Common symptoms of Dry Eye Syndrome include:

• Irritation or a gritty sensation in the eyes
• Redness
• Blurred vision
• Fatigue of the eyes
• Sensitivity to light
• A feeling of having something in the eyes

Diagnosis

Diagnosis of Dry Eye Syndrome involves a comprehensive eye examination, including:

• Patient history to determine the presence of symptoms and potential causes
• Examination of the eyelids and the surface of the eye
• Measurement of tear production and quality
• Tests to evaluate the stability of the tear film and the rate of tear evaporation

Treatment

Treatment for Dry Eye Syndrome aims to restore or maintain the normal amount of tears in the eye, minimizing dryness and related discomfort. Treatment options include:

• Artificial tears and ointments to lubricate the eyes
• Prescription eye drops to reduce inflammation or stimulate tear production
• Punctal plugs to block tear drainage and maintain moisture
• Lifestyle and environmental changes to reduce exposure to drying conditions
• Special contact lenses designed to protect the surface of the eye and trap moisture

Prevention

Preventive measures for Dry Eye Syndrome include:

• Taking breaks during long periods of screen use to rest the eyes
• Increasing humidity levels in the environment
• Wearing sunglasses outdoors to reduce exposure to wind and sun
• Staying hydrated by drinking plenty of water
• Using a high-quality air filter to reduce exposure to irritants
