Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Self-tonometry with iCare Home is performed by one hundred patients annually at Sankt Erik's Eye Hospital. The investigators want to evaluate the impact that self-tonometry results have on the clinician's choice of glaucoma treatment. The investigators also want to evaluate how often pressure peaks occur outside the clinic's opening hours.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Since a few years back, self-tonometry has been available in glaucoma care. Self-tonometry allows patients to measure their eye pressure themselves using a portable tonometer. Sankt Erik's Eye Hospital was the first healthcare provider in Sweden to use this new technology. The investigators have previously conducted studies that have shown good agreement between the measurements made by patients and the gold standard method, e.g. Goldman applanation tonometry (GAT) (Chen, Querat et al. 2016, Querat and Chen 2017). About one hundred patients perform pressure curves with self-tonometry annually.

As the method is used regularly, the investigators want to evaluate the impact of self-tonometry results on the clinician's choice of glaucoma treatment. The investigators also want to evaluate how often pressure peaks occur outside the clinic's opening hours and how much they differ from GAT.
