Mansouri K, et al. - Researchers conducted this single-center prospective study to assess the intereye correlation of continuously measured circadian intraocular pressure (IOP)-related patterns in untreated glaucoma patients. In total, 29 untreated patients with open-angle glaucoma had bilateral ambulatory 24-hour monitoring of IOP-related patterns using a contact lens sensor (CLS; SENSIMED Triggerfish). Twenty patients (mean age: 55.5±15.7 y; 51.7% women) may obtain complete bilateral CLS data. Findings revealed that there was good intereye agreement for circadian IOP-related patterns using the CLS in this group of untreated glaucoma patients. Such findings display a higher degree of intereye symmetry than previously reported with standard tonometry, in terms of IOP peak timings and amplitudes. No serious adverse events were reported with respect to CLS monitoring.
