A “delayed” encounter was defined as having a follow-up interval exceeding 33% of the recommended cycle. Patients seen for IVIs during the corresponding six-week interval a year previously were identified for study as pre-COVID-19 controls. Main outcome measures included best-corrected visual acuity (BCVA) and optical coherence tomography (OCT) assessment based on findings of intraretinal or subretinal fluid consistent with new or recurrent neovascular events.Results: The study included 183 eyes of 144 patients who underwent IVI-based care from June 18, 2020, through August 7, 2020, compared to 193 eyes of 154 patients injected during the corresponding interval 1 year before. There were 62 eyes of 46 patients seen in the study period later than scheduled (among 144 patients of 183 eyes in total), which represented a larger proportion of delayed patients compared to the previous year (31.9% vs. 14.9%, p< 0.0005). Considering the patterns from the control group, the attributed delay due to COVID-19 was 15.0% of patients. The delayed return eyes had a greater decline in BCVA (3 letters), higher rates of worsened OCT results (48%), and prompted reduction in previously prescribed injection intervals (p< 0.02).Conclusion: The unintended consequence of delayed care of patients on established care regimens should be anticipated, and mitigate strategies considered if similar restrictions are mandated in the future.Keywords: COVID-19, SARS-CoV-2, pandemic, retinal vascular diseases, anti-vascular endothelial growth factor, treatment outcomesAshkenazy NGoduni LSmiddy WEDove Medical Pressarticlecovid-19sars-cov-2pandemicretinal vascular diseasesanti-vascular endothelial growth factortreatment outcomesOphthalmologyRE1-994ENClinical Ophthalmology, Vol Volume 15, Pp 413-417 (2021)
