At Ella Eyes in Houston, TX, dry eye disease is evaluated as a multifactorial condition of the ocular surface and tear film. Patients with dry eye often present with burning, irritation, fluctuating vision, and ocular fatigue. An eye doctor may identify tear film instability, inflammation, or gland dysfunction during a comprehensive examination.
1. Meibomian Gland Dysfunction
Meibomian gland dysfunction is one of the most common causes of dry eye. The glands located along the eyelids produce the lipid layer of tears, and when they become blocked or inflamed, tear evaporation increases. This condition may develop gradually, and it is often associated with chronic eyelid margin disease. Clinical evaluation typically reveals reduced tear film quality and increased ocular surface dryness.
2. Environmental Factors
Environmental exposure plays a significant role in tear film instability. Air conditioning, wind, low humidity, and prolonged screen use can all accelerate tear evaporation. In urban areas such as Houston, TX, patients may experience worsening symptoms due to indoor climate control and digital device usage.
3. Aging and Hormonal Changes
Aging naturally affects tear production, and hormonal changes can further reduce tear volume and stability. This is particularly common in postmenopausal individuals, where androgen levels may influence meibomian gland function. Tear secretion may become less efficient over time, and symptoms may increase in severity.
4. Medical Conditions and Medications
Systemic conditions such as autoimmune disease, diabetes, and thyroid disorders may contribute to dry eye disease. Certain medications, including antihistamines, antidepressants, and blood pressure medications, may also reduce tear production. During clinical assessment, an eye doctor may review medical history to identify contributing systemic factors.
5. Contact Lens Use and Digital Eye Strain
Long-term contact lens wear can disrupt the tear film and reduce oxygen transmission to the cornea. Digital eye strain, associated with prolonged screen time, can also reduce blink rate and increase tear evaporation.
Diagnosis and Clinical Evaluation
At Ella Eyes, dry eye evaluation includes tear film analysis, corneal staining, and assessment of eyelid gland function. Both direct examination and diagnostic testing are used to determine severity and underlying cause. Indirect symptoms, such as fluctuating vision and ocular fatigue, are also considered during diagnosis.
