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.
