Abstract

Introduction/Purpose: Home intraocular pressure (IOP) monitoring helps detect elevated IOPs that may be missed during routine office visits for glaucoma. This study examined whether home IOP tonometry provides additional information that changes glaucoma management.

Methods: This study included 82 eyes from 46 patients examined by the Wills Eye Glaucoma Service that had iCare HOME tonometry done between 2020 to 2023. Patient demographic data, prior surgical interventions and medications, and management changes following home tonometry were collected. iCare HOME tonometry data and the presence of IOP spikes were also recorded. Physician interpretations of optical coherence tomography imaging and visual field testing were used to identify clinically progressing and non-progressing eyes. Fisher’s exact tests 2 and two-sample t-tests were done to determine the effects of demographic, clinical, and home tonometry parameters on management changes.

Results/Conclusions: The 82 eyes included in this study had normal office IOPs, but 72% (59 eyes) had IOP spikes on home tonometry. However, less than half (44%) of these eyes with home IOP spikes had changes in their medical or surgical management. Among non-progressing eyes with an IOP spike at home, a higher proportion did not have management changes (63% vs. 37%). Eyes with management changes had lower best-corrected visual acuities (0.07±0.10 vs. 0.2±0.25, p=0.004), higher trough home IOP (9.69±1.85 vs. 7.74±2.65 mm Hg, p< 0.001), and higher mean home IOP (14.5±2.9 vs. 12.5±3.4 mm Hg, p=0.005). These findings suggest that home IOP spikes are typically interpreted within the broader clinical context of findings from structural imaging and visual testing.
