简要总结
In this prospective device comparison study with 58 healthy eyes, the Topcon CT-1® showed statistically significant elevated intraocular pressure measurements compared to the gold standard Goldmann application tonometry.
详细描述
Introduction
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.
