Impact of Home Intraocular Pressure Telemonitoring on Intraocular Pressure Control and Glaucoma Progression

Impact of Home Intraocular Pressure Telemonitoring on Intraocular Pressure Control and Glaucoma Progression - A Randomized Control Trial

Source: ClinicalTrials.gov · Last updated 3 Sept 2026

Brief summary (registry, in English)

The goal of this clinical trial is to conduct a study randomizing glaucoma patients to home intra-ocular pressure (IOP) telemonitoring combined with Smart phone-based intervention (Management Paradigm I) or Smart phone-based intervention alone (Management Paradigm II), with the objectives to compare (1) Goldmann applanation tonometry (GAT) intra-ocular pressure (IOP) measurements over the entire study period (primary outcome measure) and (2) the rates of Retinal nerve fiber layer (RNFL) thinning (secondary outcome measure) between the two Management Paradigms. We hypothesize that glaucoma patients randomized to Management Paradigm I will (1) attain lower levels of intra-ocular pressure (IOP), and (2) a slower rate of Retinal nerve fiber layer (RNFL) and ganglion cell inner plexiform layer (GCIPL) thinning compared with those randomized to Management Paradigm II because of having a more precise assessment of intra-ocular pressure (IOP) to guide intra-ocular pressure (IOP)- lowering therapy would be feasible in Management Paradigm I. It aims to: to compare (1) Goldmann applanation tonometry (GAT) intra-ocular pressure (IOP) measurements over the entire study period (primary outcome measure) and (2) the rates of Retinal Nerve Fiber Layer (RNFL) thinning (secondary outcome measure) between the two Management Paradigms. Participants will asked to do, * Management Paradigm I: will be provided with an iCare Home and instructed to measure and upload 6 intra-ocular pressure (IOP) measurements weekly (2 days a week, 1 measurement in the early morning (5 am to 9 am), 1 during the mid-day (12 pm to 4 pm) and 1 in the evening (7 pm to 11pm)) to a secure server via iCare CLINIC (the number of weekly intra-ocular pressure (IOP) measurements follows the number of weekly blood pressure measurements in the HyperLink study). The morning measurement will include two readings with the first obtained in the supine position before getting out of the bed and the second obtained in the upright position right after. Patients may take additional intra-ocular pressure (IOP) measurements in supine position if they wake up in bed from sleep, as well as other times of the day, but this is not mandatory. These additional intra-ocular pressure (IOP) measurements will not be included for treatment decisions during the study period. * Management paradigm II: Patients will be treated with a topical prostaglandin analogue after baseline intra-ocular pressure (IOP) measurements.
