OBJECTIVE: To evaluate the impact on trends in clinical presentation of acute, primary rhegmatogenous retinal detachments (RRD) from early to late phases of the COVID-19 pandemic. METHODS: This study was a single-center, consecutive case series of 1,727 patients treated after vaccine availability ("late"; 3/29/21 to 9/26/21), corresponding time frame in previous year of pandemic ("early"; 3/30/20 to 9/27/20), and prior to pandemic ("pre"; 4/1/19 to 9/29/19). Primary outcome was proportion of patients presenting with macula-off RRD. Secondary outcomes included best-corrected visual acuity (BCVA) and primary proliferative vitreoretinopathy (PVR). RESULTS: While macula-off RRD rates were significantly (P < 0.0001) elevated in early and late cohorts compared to the pre cohort, only the early cohort showed a significant (P < 0.0001) increase in both primary PVR presentation and complex RRD repair. Patients lost to follow-up in early cohort were significantly (P < 0.0001) higher than others. Early cohort showed significantly (P < 0.0001) worse final BCVA compared to others. CONCLUSION: Patients in late pandemic were less likely to exhibit clinical features of worse RRD disease and have improved visual outcomes compared to those in early pandemic.

BACKGROUND: While the corona pandemic and the resulting containment measures affect the number of elective surgical procedures, the impact on emergency surgical interventions is less tangible. This analysis quantifies the frequency of emergency vitrectomies for retinal detachment and investigates underlying factors. METHODS: Retrospective identification of patients who underwent primary emergency vitrectomies for retinal detachment at the Cantonal Hospital of Lucerne between 01.01.2018 - 31.12.2020. Parameters were collected, including demographics, date of hospitalisation, reported onset of symptoms, pre-operative best corrected visual acuity (BCVA), involvement of the macula, and canton of residence. RESULTS: Overall, a total of 665 patients with 683 eyes underwent emergency surgery for primary retinal detachment in the time span of 01.01.2018 - 31.12.2020. Median monthly number of surgeries was 20. During the first Swiss national lockdown (16.03.2020 - 19.04.2020), a minimum of 9 vitrectomies was recorded in March 2020. A maximum of 36 vitrectomies was conducted in August 2020. The mean age of patients was 61.5 years. Of the 665 patients, 133 (20.0%) were residents of the canton of Ticino. Median pre-operative BCVA was 0.25 over all three years, and no significant reduction in pre-operative BCVA was observed during or after the lockdown. The proportion of eyes with involvement of the macula was 52.2%. In 2018, this proportion (47.6%) was significantly lower than in 2019 and 2020 (Chi2 test, p < 0.001). However, cases with macular involvement in post lockdown months were not more frequent. Median time in days from reported symptom onset to hospitalisation was 5 days. In April 2020, the proportion of patients with > 14 days symptom duration was significantly higher (Chi2 test, p < 0.001). During the lockdown, there was a significant reduction in cases from Ticino. Also, patients from Ticino showed proportionally longer symptom duration after the lockdown. CONCLUSION: A significant reduction in the number of emergency vitrectomies was observed for the initial period of the coronavirus pandemic. Delayed emergency presentation is not assumed, since there was no increase in severity (i.e. macular involvement) or prolonged symptoms in the months following the lockdown. More protracted symptoms were only observed in patients from Ticino. The initial low numbers were generally made good later in the year.
