“… 11 – 13 A significant limitation to use, however, is the relatively high number of patients failing certification, ranging from 20% in the current study to 26% in other studies, which may in part be magnified by age. 24 , 25 , 42 We also observed greater difficulty for patients to obtain measurements for the left eye compared with the right; although the exact reasons require further investigation, eye and hand dominance may be contributing factors. Nonetheless, if training and certification are successfully completed, patients generally perceived the iCare HOME as either acceptable or easy to use in concurrence with previous studies.…”

“… 23 – 26 With appropriate training and instruction, most patients were able to successfully perform self-tonometry with the advantage of obtaining intraocular pressure measurements in the patient's habitual environment and fewer visits to the health practitioner's office. 24 , 25 Previous reports investigating diurnal intraocular pressure with rebound self-tonometry have demonstrated high intraindividual variation across consecutive days, with participants exhibiting different diurnal curve patterns from day to day. 21 , 22 However, no studies to date have investigated diurnal curve fluctuations with iCare HOME for more than a week.…”

SIGNIFICANCEThis article shows that self-tonometry can provide robust measures of diurnal intraocular pressure (IOP) and also detect changes to IOP in response to treatment within a short period of monitoring. These advances in IOP monitoring may contribute to improved management of glaucoma patients and suspects.PURPOSEThe aim of this study was to prospectively investigate the utility of rebound self-tonometry performed over several weeks for detecting diurnal IOP fluctuations in glaucoma patients and suspects and also initial response to topical treatment in glaucoma patients.METHODSForty patients were recruited following glaucoma-specific examination. Subsequent to successful training with the iCare HOME tonometer, patients were instructed to measure IOP, in a sitting position, four times a day over 4 to 6 weeks. Date, time, laterality, and IOP downloaded from the tonometer and clinical examination data, including applanation IOP and corneal thickness, were analyzed. A user satisfaction survey was also administered at study completion. t Test and analysis of variance were used to compare groups and IOP across days. Pearson correlation was used to compare measurements to Goldmann applanation tonometry and IOP measurements from the first day/s to the overall mean IOP.RESULTSTwenty-seven patients (18 suspects and 9 glaucoma patients) completed data collection. Patients self-measured IOP on 118 (±29) occasions for 40 (±7.4) days. Two dominant patterns of fluctuation were revealed: peak IOP upon awakening (n = 11) and at midday (n = 13). Diurnal IOP measured in the first 7 days showed strong correlation to diurnal IOP across the entire study period (r2 = 0.82, P < .0001). Within 24 hours of treatment commencement (latanoprost 0.005% ophthalmic solution), IOP reduced from 23.9 (±5.2) to 16.1 (±2.6) mmHg. Overall, patients rated the instrument as easy to use, although difficulties with correct alignment were expressed.CONCLUSIONSRebound self-tonometry demonstrated utility for measuring diurnal IOP fluctuations in most patients, hence enhancing management of patient with or at risk of developing glaucoma.

“…Our previous data also show that the mean Icare HOME IOP was lower than that obtained with GAT 1.03 mmHg (95% LOA was between −5.98 and 3.91 mmHg) by self-measurement. 9 Despite using the same long probe for Icare TA01i and examination of reports for various age ranges, 9 , 10 , 12 , 30 , 32 , 33 the IOP obtained with Icare HOME was slightly lower than that obtained with GAT. This tendency is probably explained by 1) the instrument itself, and not the probe, because the IOP values with both self- and second party measurements are lower than those for GAT.…”

The rebound tonometer has a unique mechanism for measuring intraocular pressure (IOP) and has become popular worldwide due to its ease of use. The most notable advantages are the lack of an air-puff and need for topical anesthesia, ease of operation and transport, and the ability to use it with children. Four rebound tonometers (Icare® TA01i, Icare PRO, Icare HOME, and Icare ic100) are currently available for clinical examination. It is important to understand the characteristics of each tonometer and select the most appropriate one because the IOP values and the purpose of measurement are different. In this review, with the goal of improving the understanding of a range of tonometers, the issues with each device are discussed.

“…Moreover, Mudie et al evaluated Icare HOME and found that from 189 recruited patients, 4% failed to complete the study due to time concerns and 6% had difficulty using the device. 17 Further studies are required to assess the validity of home tonometry.…”

A wide range of relatively cheap, wearable digital devices are now available that enable self-monitoring of parameters such as heart rate, blood pressure, physical activity and sleep patterns. Although these devices are often marketed at healthy people, new technologies that permit home monitoring may also have the potential to improve the detection and management of chronic diseases including glaucoma. If patients were able to measure their intraocular pressure or perform perimetry at home, many more measurements could be obtained, with the potential to improve our ability to differentiate true change from testretest variability. Home monitoring may also improve our ability to determine efficacy of treatment and enhance patient engagement.
