Rebound tonometer comparable to Goldmann applanation

IOP measurements obtained with the rebound tonometer (Icare Pro) are more comparable to those achieved with the Goldmann applanation tonometer than those obtained with ultra-high-speed Scheimpflug technology, according to a recent study.

IOP measurements obtained with the rebound tonometer (Icare Pro) are more comparable to those achieved with the Goldmann applanation tonometer than those obtained with ultra-high-speed Scheimpflug technology, according to a study published in Investigative Ophthalmology & Visual Science (IOVS).

For this comparison study, researchers from the Medical University of Silesia, in Katowice, Poland, included 192 eyes of 96 patients, 152 of which were healthy and measured IOPs using the Goldmann applanation tonometer (GAT), a rebound tonometer (RT; Icare PRO), and ultra-high-speed Scheimpflug Technology (UHS ST). Corneal pachymetry was also done with a Scheimpflug camera and an ultrasound pachymeter (A-scan Plus, Accutome) as a comparison for Corvis ST pachymetry.

Mean IOPs were 15.6 mmHg (GAT), 15.6 mmHg (RT), and 16.1 mmHg (UHS ST). Mean central corneal thickness (CCT) was 543.7 μm (UHS ST), 547.9 μm (Pentacam) and 556.25 μm (ultrasound pachymeter).

Researchers noted a significant difference between IOP measurements obtained with GAT and RT compared to measurements obtained with the UHS ST (P P = 0.5). In addition, no significant differences were seen in CCT measured via UHS ST, Pentacam and ultrasound pachymeter.
