Dry Eye

Dry eye disease, also known as dry eye syndrome or keratoconjunctivitis sicca, is a common eye condition that occurs when the eyes do not produce enough tears or when the tears evaporate too quickly. Tears are essential for maintaining the health and comfort of the eyes, providing lubrication, nourishment, and protection to the ocular surface.

Key points about dry eye disease:

1. Causes: Dry eye disease can have various causes, including:

   • Reduced tear production due to aging, hormonal changes, certain medical conditions (such as Sjögren's syndrome), and medications.

   • Increased tear evaporation caused by environmental factors (wind, dry air, smoke), extended digital device use, and certain medications.

   • Eye surgery or medical procedures that affect tear production or composition.

2. Symptoms: The symptoms of dry eye disease can vary in intensity and may include:

   • Dryness or discomfort in the eyes.

   • Grittiness or a foreign body sensation.

   • Burning or stinging sensation.

   • Excessive tearing (as a response to the dryness).

   • Blurred or fluctuating vision.

   • Sensitivity to light.

   • Eye redness or irritation.

3. Diagnosis: Eye doctors can diagnose dry eye disease through a comprehensive eye examination, which may include:

   • Evaluating the quantity and quality of tears.

   • Measuring tear production using a Schirmer test.

   • Assessing the health of the ocular surface.

   • Identifying contributing factors or underlying conditions.

4. Treatment: The treatment of dry eye disease depends on its severity and underlying causes. Common treatment options include:

   • Artificial tears or lubricating eye drops to provide moisture to the eyes.

   • Prescription eye drops that increase tear production or reduce inflammation.

   • Punctal plugs, small devices inserted into the tear drainage ducts to help tears stay on the ocular surface longer.

   • Lifestyle changes, such as using a humidifier, taking breaks from digital devices, and protecting the eyes from windy or dry environments.

   • Dietary supplements containing omega-3 fatty acids, which may help improve tear production.

5. Prevention: Some measures can help prevent or manage dry eye symptoms:

   • Blink regularly, especially when focusing on screens or reading.

   • Follow good eyelid hygiene practices.

   • Stay hydrated by drinking enough water.

   • Use proper lighting when reading or using digital devices.

Dry eye disease is a chronic condition that may require ongoing management. It's important for individuals experiencing symptoms of dry eyes to seek evaluation and guidance from an eye care professional. Effective management can help alleviate discomfort and prevent potential complications that may arise from untreated dry eye disease.
