Comparison of Sensimed Triggerfish With Goldmann Applanation Tonometry and Perkins Tonometry

Comparison of Sensimed Triggerfish (TF) 24 Hour IOP Monitoring With Goldmann Applanation Tonometry (GAT) and Perkins Tonometry in Glaucoma Patients

This prospective, crossover study is designed to correlate SENSIMED Triggerfish® (TF) continuous IOP monitoring with conventional 24 h intraocular pressure profiles in glaucoma patients. There are two control measurements: The GAT/Perkins profile in the same eye in the second night and the GAT/Perkins profile in the same night in the fellow eye. Therefore, each eye serves as test eye and also as control for the second test eye.

Inclusion Criteria:

• Patient is able to comply with the study procedure
• Patient must be ≥ 18 years old
• Diagnosis of primary open angle glaucoma (EGS criteria)
• Similar behaviour of IOP in both eyes in former IOP profiles
• Patient has consented to be in the trial and signed informed consent is available before any study related procedures are carried out
• Visual Acuity of 20/200 or better in both eyes
• Ability of subject to understand the character and individual consequences of the study
• For women with childbearing potential, adequate contraception
