Reliability of Dynamic Contour Tonometry (DCT) — DCT  

Intraocular Pressure Clinical Trial

Official title:
Study of Test-retest Reliability of Dynamic Contour Tonometry and Its Correlation With Goldmann Applanation Tonometry

Clinical Trial Summary

Study wants to test reliability Dynamic Contour Tonometry (DCT) in measuring intraocular pressure (IOP) and Ocular Pulse Amplitude (OPA). IOP values obtained with DCT will then be compared with IOP values obtained with Goldmann Applanation Tonometry (GAT), actually the gold standard technique.

Clinical Trial Description

Healthy volunteers recruited among subjects who underwent a routine ophthalmologic evaluation or among students and workers both at our clinic, will undergo a series of 5 DCT to evaluate eventual differences among the measurements.

A diurnal IOP curve performed though GAT, composed of 3 measurements (9am, noon, 4pm) will be taken 1 to 7 days before the DCT.

At the end of the DCT measurements a last GAT will be taken to control eventual IOP changes versus previous GAT values obtained through the diurnal curve.

After 3 weeks observers will contact patients to record eventual adverse events. If examiners consider it as necessary, a safety ophthalmological evaluation will then be performed. ;
