Summary of Diagnosis and Management of Dry Eyes

Management of the dry eye problem should include clinical treatment of the condition as well as consultation about working habits and the work environment. Consider the following:

  • Aggressively diagnose �dry eye�.

  • One study found an average blink rate of 3.6 blinks/min at the computer � this is an inter-blink interval of 16.7 seconds. Clearly a TBUT of 10 seconds (normal threshold for clinical significance) is not adequate. In the presence of ocular symptoms, even slight deficiencies in tearing should be treated.

  • Management of the condition with artificial tears or punctal plugs

  • If the computer screen is too high it results in a larger ocular aperture. The computer screen should be placed so that the worker is habitually looking downward 10-20 degrees - usually the top of the screen should be below eye level. Many workers, especially who are shorter, are looking straight ahead or up at the screen. The computer screen can often be lowered by removing it from the CPU.

  • If the patient works in a location with a ventilation breeze, they should change the airflow pattern or re-orient the workstation.

  • Give the patient feedback that their problem is caused by dry eyes, and ask them to concentrate on blinking more frequently, especially when they begin to notice the symptoms of dry eye.

  • It helps to take an occasional 2-minute break, look into the distance, and concentrate on blinking.
