Objective: To determine whether we are able to obtain the same values of intraocular pressure using three different non-contact devices. Patients and methods of examination: The study included 100 eyes of 50 people, of whom 25 were women (25-82 years) and 25 men (21-81 years).
The first group included 12 glaucoma patients (6 on prostaglandins) and 13 healthy individuals. The second group included 8 glaucoma patients (3 on prostaglandins) and 17 healthy subjects.
Intraocular pressure (IOP) was measured by three devices: non-contact Tonometer TX-F, non-contact Tonometer TX-20P (Canon) incorporating optical pachymeter, and Ocular Response Analyser II (Reichert). To eliminate the role of corneal thickness on IOP, the Tomey Hand Pachymeter SP100 was used with the noncontact Tonometer TX-F.
The time difference between individual measurements was 15-30 minutes.
