Intraocular Pressure Telemetry for Managing Glaucoma During the COVID-19 Pandemic

Dezember 2020
IOP measurements acquired by the patients during the lockdown period were collected by physicians who were located remotely. A questionnaire was sent to 10 participating study centers to evaluate the clinical impact of remote monitoring of IOP via the IOP sensor system.
