Evaluation of a new rebound tonometer for self-measurement of intraocular pressure

Abstract

Sub-titleSelf-measurement using Icare Home showed good agreement with Goldmann applanation tonometry. Icare Home self-measurement was well accepted and reliable results obtained by 3 in 4 subjects, suggesting potential use for home measurement of intraocular pressure.

Monitoring daily intraocular pressure fluctuations with self‐tonometry in healthy subjects

“…We found a mean IOP difference between the GAT and icare ® Home measurements of 0.15 mmHg, similar to the results obtained in previous studies of patients with glaucoma (Dabasia et al. ; Chen et al. ; Termuhlen et al.…”

“…Self‐tonometry measurements made by patients with glaucoma using icare ® Home tonometers were evaluated in previous studies and found to agree well with GAT results (Dabasia et al. ; Chen et al. ; Termuhlen et al.…”

“…() and Dabasia et al. () in which 78% and 84% of participants' measurements, respectively, were within this interval. This difference could be because healthy subjects are not accustomed to IOP measurements and tend to be tense when making them.…”

Comparison of self-measured diurnal intraocular pressure profiles using rebound tonometry between primary angle closure glaucoma and primary open angle glaucoma patients

“…The within measurement intra-class correlation coefficient (ICC) of Goldmann applanation tonometry and rebound tonometry were 0.98 (95% confidence interval (CI): 0.97–0.99) and 0.94 (95% CI: 0.90–0.96), respectively. Although rebound tonometer was showed may underestimate the IOP compared to Goldmann applanation tonometry measurements in previous studies,[32] We evaluated the correlation and agreement between patient-measured IOP using rebound tonometry with ophthalmologist-measured IOP using Goldmann applanation tonometry in our cohort, and found that both modes of IOP measurements correlated well with each other, a good agreement was also identified with a mean difference ± 1 standard deviation (SD) of 0.15 ± 0.65 mmHg ( p = 0.682) between Goldmann applanation tonometry and rebound tonometry. The between-measurement ICC of these two tonometries was 0.72.…”

Vergleichbarkeit des Icare-Pro-Rebound-Tonometers mit der Goldmann-Applanations- und Non-Contact- Tonometrie bei sehr unterschiedlichen Augeninnen-drücken und zentralen Hornhaut-Dicken

“…Allerdings wird auch deutlich, dass die Übereinstimmung der Messwerte zwischen GAT und NCT deutlich besser ist, insbesondere außerhalb des Normbereichs. Dennoch erlaubt das Icare neben dem Einsatz bei Kindern oder anderen Patienten, bei denen eine Untersuchung an Spaltlampe oder mit NCT nicht möglich ist, inzwischen auch eine Selbsttonometrie durch den Patienten [3,4]. Somit ermöglicht dieses Gerät eine recht verlässliche Bestimmung des Augeninnendrucks und damit eine bessere Führung dieser Patienten.…”
