Q: What are some of the warning signs of Dry Eye? How is it best detected?
A: Warning signs of dry eye can accumulate gradually over time. For example, contact lens wearers may incorrectly assume their lenses are old and need to be replaced. Other times, the eyes become watery, burn, or itch. Many cases are sub-clinical – they can only be diagnosed with the use of microscopic detection and special equipment! We look at tear quality, tear meniscus, and gland structure. Research suggests testing the tear osmolarity is a reliable indicator of dry eye disease, for pre-treatment and post-treatment assessment.
Q: What can cause Dry Eye?
A: Age, gender (female) and certain medications can cause dry eye symptoms. Other dry eye risk factors include work environment (dry offices or factories), the weather, and geographical location.
Q: What happens at a dry eye exam?
A: To diagnose dry eye disease, the eye doctor can use a biomicroscope to examine whether there are plugged oil glands in the lid or any dry patches on the cornea present. A yellow stain called fluorescein can help us see how quickly the tears evaporate. We also look for eyelid issues like blepharitis (inflamed crusty lids) or Demodex mites which can worsen dry eye symptoms.
