ABSTRACT
PURPOSE: In March 2020, the sudden rise in the number of SARS-CoV-2 infections in France led the government to impose a strict lockdown during which all non-urgent medical consultations were postponed. From March 17 to May 10, 2020, private medical practices were closed, and telemedicine was encouraged. The consequences on ophthalmic care were dramatic, with over 90% of scheduled consultations canceled. The goal of this study was to describe consultations during the 2-month strict lockdown in Paris and to analyze its impact on the visual outcomes of patients consulting in the ophthalmology emergency department (OED). METHODS: Data of patients who presented to the OED of the A. de Rothschild Foundation Hospital (RFH), a tertiary ophthalmology center in Paris, France, during the lockdown period and its immediate aftermath were analyzed. The results were compared to the same time periods in the years 2018 and 2019. Four time periods were defined and numbered chronologically: March 17 to May 10, 2018 (period 1); March 17 to May 10, 2019 (period 2); March 17 to May 10, 2020 (period 3, the lockdown period); May 11 to June 9, 2020 (period 4, the post-lockdown period). RESULTS: The number of consultations was reduced by more than 50% during the lockdown period (n=2909 patients) and by 30% during the post-lockdown period (n=2622) when compared to periods 1 (n=7125) and 2 (n=8058). Even though LP4 saw an increase in the number of patients consulting, there was no increase in the rate of severe diseases (12.8% during LP3 vs. 11.1% during LP4), and the proportion of patients who were admitted was statistically similar (4.3% vs. 3.6%). Neuro-ophthalmic diseases were the most common during LP3 and LP4. Neovascular glaucoma was twice as common during post-LP4 (P=0.08). We noted a significant increase in patients with graft rejection consulting in our OED during the post-LP4 (P<0.001). These results were likely related to a delay in follow-up consultations due to the lockdown measures. CONCLUSION: The reduction in the number of consultations in our OED during the lockdown period affected both minor emergencies and severe ophthalmic diseases, but with no significant delay in diagnosis. More longitudinal and longer study is needed to confirm this and to retrospectively analyze the effects of the COVID-19 outbreak and lockdown.
