Purpose Study of possibility of use and evaluation of transpalpebral scleral DIATON tonometer clinical use effectiveness in pediatrics The following factors were exclusion criteria from the study Upper eyelid and sclera pathology, which are the contraindications for transpalpebral diaton-tonometry Cornea pathology, influencing prognosticly the applanation tonometry results

Patients and Methods The prospective comparative case series clinical study was done in 60 children (120 eyes), age distribution 7-16 years. During the study Goldmann tonometer and transpalpebral scleral DIATON tonometer were used. Intraocular pressure measuring was realized with three different DIATON devices at the same day time.

Researchers’ experience of DIATON tonometery application in clinical practice was not less than 1 month IOP was measured with Goldmann applanation tonometer and transpalpebral scleral Diaton tonometer using traditional methodology, all ophthalmotone measurements were realized the patients being in the sitting position with time interval being 2-3 minutes between two investigators Picture 2 Transpalpebral scleral diaton tonometer Picture 3 Methodology of transpalpebral tonometry

Results and discussion For OD mean modified tonometry value with Golmann was 19,98±0,4 mmHg, mean IOP value measured with DIATON was 19,40±0,47 mmHg (t=0,65, df = 117, p> 0.05), for OS mean modified tonometry value with Golmann was 19,39±0,48 mmHg, mean IOP value with DIATON was 19,41±0,42 mmHg (t=0.99, df = 117, p> 0.05).

Conclusion Clinical study of possibility of transpalpebral scleral DIATON application in children tonometer demonstrated its high accuracy. The recommended child’s age for IOP measuring with this tonometer is 7-16 years. The advantages are: simplicity of use without any additional medicines, psychological acceptability by children, significant time saving for ophthalmotonometry procedure
