Information On Intraocular Pressure; Support Materials - Icare HOME2 Instruction Manual

use the same probe for both. After you have taken the measurements, place
the probe back in its container and dispose of it in a mixed waste bin. Use a
new, unused probe when you take a measurement the next time.
You can measure your eye pressure when you are sitting, standing, or lying
down (supine position). The tonometer includes infrared eye recognition
sensors to identify which eye, right or left, you are measuring.
After the measurement, you can transfer the measurement data to iCare
CLINIC or iCare CLOUD using your computer or mobile device.
Familiarize yourself thoroughly with the tonometer, software, and the
operational procedures before use.

Information on intraocular pressure

The normal eye pressure ranges from 10 to 20 mmHg (1). The risk for
glaucoma increases if the eye pressure is above this range. In normal tension
glaucoma, the optic nerve is damaged even though the eye pressure is not
very high. The optimal target pressure in glaucoma and ocular hypertension
needs to be defined case by case. Ask your healthcare professional for
your target eye pressures. Agree when you need to contact your healthcare
professional about your eye pressure measurement results.
Follow your healthcare professional's instructions on the frequency of
measurements. Unless otherwise instructed, the recommended frequency
of measurements is 3-6 times a day. Keep a record of your eye pressure
for your healthcare professional. A single measurement does not provide
accurate information on your eye pressure level. You need to take and record
several measurements over time. Try to measure your eye pressure at the
same times each day for consistency.
An elevated eye pressure as well as fluctuations in the eye pressure are
underlying risk factors for glaucoma (2,3). When you measure your eye
pressure in a variety of situations and at different times of the day, you and
your healthcare professional get a comprehensive view of the changes in
your eye pressure and the effectiveness of your medication.
