Abstract
INTRODUCTION: COVID-19 has had a tremendous impact on our everyday life. A growing body of evidence indicates that subsequent lockdowns and fear of exposure may have impacted patient care. We analyzed data on incidence and time to surgery in cases of rhegmatogenous retinal detachments (RRD) at three defined time points before, during, and 1 year after the first lockdown period in Germany. METHODS: In this single-center study, we identified all patients who were admitted and treated for a primary RRD in April and May 2020, the time of the first lockdown period in Germany, and compared them with cases of the same time period in the years 2019 and 2021. The time from first occurrence of symptoms to surgery as well as visual outcome was analyzed. RESULTS: A total of 192 patients presented to our tertiary academic referral center with a RRD during the months of April and May in 2019 (72 patients), 2020 (62 patients), and 2021 (58 patients) and were included in this study. There were no significant differences with regard to gender and age. In 2019, the time interval between occurrence and presentation to our hospital amounted to a mean of 5.96 days and in 2021 to mean of 5.45 days. However, in 2020, the time between occurrence and presentation was significantly longer with a mean of 15.36 days. The number of patients presenting with a macula-on retinal detachment was also lowest in 2020 (39.2%) compared to 2019 (50.7%) and 2021 (50.0%). Furthermore, with 1.24 logMAR the mean BCVA upon initial presentation was lower in 2020 compared to 0.93 logMAR in 2019 and 1.06 logMAR in 2021. Six to twelve weeks following surgery, visual acuity had improved in 56.1% of patients in 2019 and 60.0% of patients in 2021 as compared to 59.0% in 2020. CONCLUSION: We found significant differences in terms of elapsed time from first symptoms to surgical management for patients in 2020 in comparison with the same time period in 2019 and 2021. Less strict lockdown policies appear to impact patient behavior and patient care. Further measures, such as questionnaires, might help address which measures may provide safer circumstances for patients to consult health care providers in the case of future strict lockdowns.
