Abstract

Purpose: The aim of this study was to examine the impact of self-tonometry on clinicians' decision in glaucoma treatment.

Materials and methods: Medical records of 133 patients who had performed self-tonometry using iCare® Home between January and December 2019 were retrospectively reviewed. Inclusion criteria were as follows: age over 18 years, all types of glaucoma, as well as ocular hypertension and glaucoma suspect, compliance with tonometer manufacturer's recommendations and monitoring over at least 2 days. The data consisted of age, gender, diagnosis, visual field index, rate of progression and type of treatment pre- and post-intraocular pressure (IOP) phasing. The following IOP measurements were used to calculate the mean and maximum IOP, and range over each day and consecutive days: Goldmann applanation tonometry (GAT) measurements from referral and training visits and iCare® Home measurements made by the trainers and the patients themselves. A total of 90 patients were included.

Results: Clinicians were satisfied with the actual treatment in 54.4% of the cases. There was a statistically significant difference between the clinicians' decision to maintain same treatment or to escalate therapy for all the mean and maximum IOPs measured on each single day and over a 2- or 3-day period (p < 0.002).

Conclusion: Our results suggest that the presence of high IOP values obtained with self-tonometry supports an intensification of glaucoma treatment. Self-tonometry provides clinicians with an important complement for clinical decision-making, and under- or over-treatment may be avoided for the benefit of patients.

Keywords: Goldmann applanation tonometry; glaucoma treatment; iCare® Home; intraocular pressure; self-tonometry.
