Guide to treating patients with dry eye disease at the optician's

It is important to establish a procedure for treating patients with dry eye at the optician's. There are four main steps to be followed:

Step 1: Detection. Checking and assessing symptoms. Anamnesis.
It is a good idea to establish a procedure, check symptoms methodically and record the results.

A series of questionnaires approved by the scientific community are available to all professionals, including the OSDI test, McMonnies, DEQ-5 and SPEED.

Step 2: Assessing signs using non-invasive techniques.
People with dry eye syndrome often suffer visual disorders, meaning that eye care professionals should perform a visual acuity test if they suspect the patient has dry eye.

During observation through the slit lamp, it is advisable to perform the following tests:

  1. Estimation of the height of the tear meniscus.
  2. Assessment of the eyelids and lashes.
  3. Assessment of the integrity of the conjunctiva and cornea.

Step 3: Assessing signs using invasive techniques.
The most frequent tests include:

  1. Assessing the integrity of the conjunctiva and cornea after applying fluorescence.
  2. Assessing the integrity of the conjunctiva by applying lissamine green.

Step 4: Action. Treatment, monitoring and remission.
Once the tests have been completed, the grade of dry eye can be determined. If the disorder is at an early stage, specific products can be recommended to relieve the symptoms. If the disease is more advanced, the patient should be referred to an ophthalmologist.
