Dry eye syndrome - Diagnosis 

Diagnosing dry eye syndrome 

Your GP should be able to diagnose dry eye syndrome by looking at your symptoms and your medical history. They may examine you to check for other conditions and complications.

Tell your GP about any symptoms that you have, not just ones that affect your eyes, as you may have another medical condition as well.

Your GP will also want to know about:

  • any medicines that you are taking
  • your personal circumstances - for example, if you work on a computer all day

These may hep your GP identify a possible cause of your dry eye syndrome.

Referral to an optometrist

Your GP may refer you to an optometrist for a check-up. Optometrists are trained to recognise sight defects and eye conditions. Although your GP may refer you to an optometrist, they are private practitioners and charge for their services.

Your optometrist will use special equipment to examine your eye, and will be able to confirm whether you have dry eye syndrome and any other associated conditions and complications. They can also give you advice about treatment.

There are a number of tests that your optometrist can carry out in order to assess the quality and quantity of your tears. Two of these tests are described below.

The Schirmer test

In this test, small strips of blotting paper are placed under your eyelid. After five minutes, the strips are removed and studied in order to determine how wet the paper is.

The Rose Bengal test

In this test, a non-toxic dye, known as Royal Bengal, is dropped on the surface of your eye. The distinctive red colour of the dye allows the ophthalmologist to see how well your tear film is functioning and how long it takes for your tears to evaporate.

Referral to an ophthalmologist

If the diagnosis is uncertain, or specialist tests and treatment are needed, your GP may refer you to an ophthalmologist. Ophthalmologists are surgeons who specialise in eye conditions. Like optometrists, they use special equipment and techniques to examine the eye.

The ophthalmic team

  • An optometrist examines eyes, tests sight, and prescribes and dispenses spectacles and contact lenses. Optometrists are trained to recognise eye conditions and sight defects. 
  • An ophthalmic medical practitioner (OMP) is a medical doctor who specialises in eye care. They examine the eyes, test sight, diagnose abnormalities and prescribe corrective lenses. 
  • An ophthalmologist is a medical doctor who specialises in eye conditions and their treatment or surgery. They mainly work in hospitals and hospital eye departments. 
  • A dispensing optician fits prescriptions for spectacles that are provided by optometrists, OMPs or ophthalmologists. They may also fit contact lenses. A dispensing optician does not carry out eye examinations. 
  • An orthoptist specialises in problems relating to eye movement and the eyes working together. This includes squint, lazy eye and double vision. 
  • An ophthalmic nurse is a nurse who has developed skills in eye care. Ophthalmic nurses work in hospital eye departments.
