Home tonometry metrics linked to visual field loss in glaucoma

A retrospective study of 94 treated open-angle glaucoma patients (150 eyes) compared in-office and remote (home) tonometry metrics for association with visual field progression. Standard IOP metrics (mean, max, min, range, SD, coefficient of variation) from either setting showed no significant association with progression, but novel remote tonometry metrics measuring average and total IOP excess above a patient's target pressure were significantly associated with faster visual field progression; equivalent in-office metrics were not. The authors state these findings suggest remote tonometry may capture clinically relevant IOP burden not reflected in conventional measurements, and support prospective validation of remote monitoring and threshold-based metrics.

Most relevant for: Patients with treated primary, juvenile, pseudoexfoliative, or pigmentary open-angle glaucoma undergoing IOP monitoring.
