32740067 To reduce disease transmission, national regulatory agencies temporarily recommended curtailment of all nonurgent office visits and elective surgeries in March 2020, including vitreoretinal outpatient care in the USA. […] The effect of these guidelines on utilization of vitreoretinal care has not been explored to date. […] Retinal outpatient visits, new patient visits, intravitreal antivascular endothelial growth factor injections and in-office multimodal retinal imaging has seen a significant decline in utilization in the early phase of the pandemic. […] Telemedicine visits, enabled by new national legislation for all areas of medicine, have been adopted to a modest degree by the retina community.
