Overview
Dry eye is not one condition. Sometimes there is not enough tear fluid; far more often the oil layer that stops tears evaporating is failing, usually because the glands in the eyelids are blocked. The two need different treatment, which is why over-the-counter drops work for some people and do nothing for others.
A dry eye appointment exists to tell those apart and to treat the mechanism, not just the symptom.
What happens during the visit?
- A symptom questionnaire and a history that covers screens, medication, and environment.
- Measurement of tear volume and how fast the tear film breaks up.
- Examination of the eyelid margins and the oil glands, sometimes with gland imaging.
- Staining dyes to show where the surface is damaged.
- A treatment plan, which may involve lid hygiene, warm compresses, prescription anti-inflammatory drops, punctal plugs, or in-practice gland treatments.
Who should book one?
Anyone with eyes that burn, sting, feel gritty, or — counter-intuitively — water constantly. Also worth a visit if contact lenses have become uncomfortable, if your vision blurs and clears when you blink, or if you are considering laser surgery.
How to prepare
- Do not wear contact lenses on the day.
- Skip eye make-up — the lid margins need to be visible.
- List every medication. Antihistamines, antidepressants and blood pressure drugs are common culprits.
- Bring whatever drops you already use, including the boxes.
