Symptoms of Dry Eye Syndrome

 If your eyes can't produce enough tears or maintain a consistent tear film, it could lead to dry eye syndrome. This condition might cause bacterial infections or inflammation on the eye surface, potentially resulting in corneal scarring. Despite its discomfort, dry eye syndrome rarely leads to permanent vision loss.

Common Symptoms:

• Burning sensation in the eyes
• Eye pain
• Redness of the eyes

Additional Signs:

• Watery eyes
• Stringy mucus
• Eyes fatigue quicker, making reading or prolonged computer use challenging
• Hazy vision
• Heavy eyes

Causes of Dry Eye Syndrome

Tears consist of three layers: an oily outer layer, a fluid middle layer, and a mucous inner layer. Dry eye syndrome occurs when the glands producing these tear components are irritated or fail to produce enough fluid, oil, or mucus. Insufficient oil in tears leads to rapid evaporation, leaving the eyes unable to maintain moisture adequately.

Reasons for Dry Eye Syndrome:

• Hormone replacement therapy (HRT)
• Allergies from exposure to wind or dry air
• LASIK (Laser Assisted Eye Surgery)
• Extended use of contact lenses, exacerbated by certain medications
• Inadequate blinking during prolonged computer use

Risk Factors for Dry Eyes

Individuals over 50, particularly women, are more prone to dry eye syndrome, with an estimated 5 million affected Americans in this age group. Pregnant women, those on hormone replacement therapy, and women experiencing menopause are also at higher risk.

Additional Risk Factors:

• Persistent allergies
• Thyroid disorders causing eye bulging
• Autoimmune diseases like lupus or rheumatoid arthritis
• Sleeping with slightly open eyes, leading to exposure keratitis
• Rare vitamin A deficiency

Some experts suggest prolonged exposure to blue light from computer screens may contribute to dry eye syndrome. While computer screens may not surpass sunlight in blue light exposure, extended screen time reduces blinking, resulting in drier eyes.

To alleviate evening dry eye, consider applying eye ointments overnight to maintain moisture. Hydrating the ocular surface during the day may improve symptoms by evening.

Treatment of Dry Eye Syndrome

Eye Drops & Artificial Tears

Commonly, dry eye is managed with eye drops enhancing eye moisture. Artificial tears are effective for some individuals, available as drops, gels, or ointments over-the-counter. Look for components like carboxymethylcellulose and electrolytes for moisture retention.

Lacrimal Canal Plugs

Eye doctors may use plugs to seal drainage pores, reducing tear loss. This reversible, painless technique becomes a permanent solution for severe cases.

Medications

Cyclosporine (Restasis), an anti-inflammatory immunosuppressant, is a prevalent medicine. It increases tear volume and lowers the risk of corneal damage. For severe dry eye, corticosteroid eye drops may be necessary temporarily. Alternately, cholinergics like pilocarpine stimulate tear production. If a medication causes dry eyes, your doctor may recommend an alternative.
