INDEPENDENCE OF THE
TRANSPALPEBRAL SCLERAL
TONOMETRY FROMTHE THICKNESS
OF THE EYELID
I ncreased intraocular pressure (IOP) is one of the important risk factors
for glaucoma. An accurate IOP assessment is crucial for early detection,
diagnostics and monitoring of glaucoma. Non-corneal IOP measurement
with Diaton tonometer is performed through the eyelid. There are no a
direct contact to the cornea or to the conjunctiva. Diaton tonometer is in-
dicated for corneal diseases, postoperative conditions of the cornea, for a
bedside diagnosis, etc. Here we examined a dependence of the transpal-
pebral scleral tonometry on the thickness of the eyelid in an unexplained
sequence of patients during the consultation.
Methods: 43 patients, 15males and 28 females (a total of 86 eyes) with age
range from 16 to 80 years old: 51.0 (31.5-69.0) years [median (1st quartile
- 3rd quartile)] was investigated. The eyelid thickness was measured us-
ing the Tomey ultrasound device DU-800. Measurements were performed
sonically by immersion on each eye tarsus-parallel and perpendicular to
the tarsus.
The mean of these two measurements was defined as eyelid thickness.
The IODmeasurement on each eye was performed by Diaton (Tonom. Ltd,
Muenster). The data were analyzed with non- parametric statistics.
Results: The average of right eyes IOP was: 15.0 (12.0-17.0) mmHg, left
eyes: 14.0 (12.0-16.0) mmHg, p = 0.605. The average of right eyelids thick-
