Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Intraocular pressure (IOP) measurement is crucial in glaucoma diagnosis and treatment. We compared a non-contact air tonometer (Topcon CT-1®) with the gold standard Goldmann Applikation tonometer (GAT).
Methods:
In this prospective, mono centric device comparison study, only healthy eyes were enrolled. IOP was measured three times with the Topcon CT-1® followed by three times GAT. Mean IOP was calculated and compared with a paired t-test, a linear regression and a Bland-Altman analysis.
