Based on the local alert levels in Nagano, five periods during the COVID-19 pandemic were further analyzed: epidemic 1 (state of emergency), inter-epidemic 1, epidemic 2 (second epidemic duration), inter-epidemic 2, and epidemic 3 (third epidemic duration). Patients' characteristics, including symptoms' duration before visiting our hospital, macula status, and retinal detachment (RD) recurrence rate in each period, were compared with those in a control group.<h4>Results</h4>There were 78 patients in the pandemic group and 208 in the control group. The pandemic group had a longer duration of symptoms than the control group (12.0 ± 13.5 days vs. 8.9 ± 14.7 days, P = 0.0045). During the epidemic 1 period, patients had a higher rate of macula-off RRD (71.4% vs. 48.6%) and RD recurrence (28.6% vs. 4.8%) than the control group. This period also demonstrated the highest rates compared to all other periods in the pandemic group.<h4>Conclusion</h4>During the COVID-19 pandemic, RRD patients significantly delayed visiting a surgical facility. They showed a higher rate of macula-off and recurrence compared to the control group during the state of emergency than during other periods of the COVID-19 pandemic, although the difference was not statistically significant due to the small sample size."],"journal":["Japanese journal of ophthalmology"],"pagination":["255-263"],"full_dataset_link":["https://www.ebi.ac.uk/biostudies/studies/S-EPMC9932397"],"repository":["biostudies-literature"],"pubmed_title":["Impact of local COVID-19 alert levels on rhegmatogenous retinal detachment."],"pmcid":["PMC9932397"],"pubmed_authors":["Hirano T","Hoshiyama K","Murata T","Chiku Y","Iesato Y"],"additional_accession":[]},"is_claimable":false,"name":"Impact of local COVID-19 alert levels on rhegmatogenous retinal detachment.","description":"<h4>Purpose</h4>To investigate the impact of the local alert levels regarding coronavirus disease 2019 (COVID-19) on the clinical patterns of rhegmatogenous retinal detachment (RRD) in Japan.<h4>Study design</h4>Retrospective, single-center, consecutive case series.<h4>Methods</h4>We compared two groups of RRD patients, a COVID-19 pandemic group and a control group.
