IOP measurement results with diaton tonometer are independent of inter-examiner variability.

The results of the mutual clinical study carried by Russian and German scientists show that the inter-examiner variability doesn’t affect the results of transpalpebral transscleral diaton-tonometry.

In the study IOP measurements were carried out by 3 examiners, one of them had long-term experience with diaton tonometer, and the other two successfully completed an intensive measurement course followed with the final exam. No significant differences in tonometer’s results received by three examiners were found.  The divergency of results was minimal because the special training course was passed by the new diaton tonometer users. Therefore the importance and necessity of obtaining a stable skill in working with diaton is emphasized once again.

Based on the study results it can be concluded that non-corneal diaton tonometry is a complementary reliable method of intraocular pressure measurement. In particular, diaton tonometer makes it possible to determine IOP pressure values in patients who have contraindications to standard tonometric methods (e.g., corneal ulcer, corneal pathology, “dry eye” syndrome). The handy, small diaton tonometer is also used for screening, for glaucoma control, for diagnosing and in bed rest patients.
