We also performed a paired analysis, which included patients who were examined in both periods, comparing the number of visits and medications.Results: The total number of outpatients clinical visits, visual field exams, surgical procedures and medications released decreased 92.52% (7117 vs 532), 93.84% (1525 vs 94), 72.74% (682 vs 145) and 19.63% (23,259 vs 18,692), respectively, when the pre-pandemic and pandemic periods were compared. The mean number of annual clinical visits per patient (1.8 ± 0.79 vs 1.04 ± 0.18, p< 0.0001) and surgical procedures per patient (1.46 ± 0.92 vs 1.13 ± 0.41, p< 0.0001) decreased significantly, whereas the mean number of medications released per patient did not change significantly (28.62 ± 19.11 vs 30.34 ± 20.15, p=0.97). In the paired analysis, the mean number of visits (n=423 patients) decreased from 1.86 ± 0.76 to 1.04 ± 0.19 (p< 0.0001) and the mean number of medications (n=561 patients) decreased from 33.44 ± 18.61 to 31.97 ± 19.86 in the pre-pandemic and pandemic periods, respectively (p=0.393).Conclusion: The Covid-19 pandemic dramatically decreased the number of outpatient visits and surgical procedures, impacting the follow-up of glaucoma patients in our service. We encourage other health care units to verify the impact of the pandemic in their own population to better prepare for a possible overload of uncontrolled glaucoma patients in the future.Keywords: glaucoma, Covid-19, SARS-CoV-2, pandemic
