Glaucoma (iop) Eye Test For Children With Tonometer Diaton - Clinical Study

Clinical Use of Transpalpebral Scleral DIATON Tonometer in Pediatrics

Professor E.I. Sidorenko, E.Y. Markova, MD, Russian State Medical University, Morozov Children’s Clinical Hospital, Moscow

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

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
