Comparison of Gonioscopy With Cirrus and Visante — ASOCT  

Open Angle Glaucoma Clinical Trial

Official title:
Comparison of Visante and Cirrus Optical Coherent Tomography for Assessment of the Anterior Segment

Clinical Trial Summary

The aim of this study is to analyze similarities and evaluate interchangeability of Visante and Cirrus OCT (optical coherent tomography)and to compare agreement between gonioscopy and the two systems for evaluation of anterior segment parameters.

Clinical Trial Description

All participants underwent routine ophthalmic examination by their physician. Three independent examiners performed gonioscopy using Spaeth Gonioscopic Grading System. Findings were recorded independently along with risk assessment of angle being closed as: high, medium, and low or no risk. Patient information was not available to doctor during gonioscopy. One eye of each patient was imaged using both Visante and Cirrus OCT. Imaging was performed under scotopic and photopic conditions and obtained from horizontal (3:00 and 9:00 o'clock) and vertical (6:00 and 12:00 o'clock) meridians. The same experienced independent examiner performed all Cirrus measurements. Visante was performed by 3 trained technicians using same protocol.

OCT images were exported and masked to be evaluated for presence of open or closed anterior chamber angle. Masked images were presented with no other patient information available to two examiners with glaucoma training working together to score on basis of iridocorneal angle as, closed (0 degree), high possibility (10 degree), medium risk (20 degree), and low or no risk (> 30 degree). ;
