Effect of Lockdown and Unlock Following COVID-19 on the Presentation of Patients With Endophthalmitis at a Tertiary Eye Center Over One Year

Introduction Endophthalmitis is an emergency where patients need immediate intervention to salvage both vision and the globe. Regular follow-up care and close monitoring of the status of the patient are crucial in determining the final outcomes of the treatment. While there is ample literature on the epidemiology and demography of endophthalmitis across the globe, no information exists on the effect of the coronavirus disease 2019 (COVID-19) pandemic on the presentation patterns of endophthalmitis. Objectives To describe the impact of the lockdown and unlock phases of the COVID-19 pandemic on the presentation of endophthalmitis at a tertiary eye care center in India. Methods This cross-sectional hospital-based study included 1,253 patients presenting between March 25, 2017, and March 31, 2021. The data on the patients diagnosed with endophthalmitis in one or both eyes presenting during the lockdown and unlock phases were compared with the respective time periods in the previous three years before COVID-19. Results The patient numbers dropped to 42.18% (27/64) of pre-COVID-19 volumes during the lockdown phase. There was a near-complete recovery of the outpatient numbers to 85.71% (26/30) of pre-COVID-19 volumes by March 2021. This gradual incremental trend was seen in etiology due to post-surgery (88%) and endogenous (159%) infections while post-traumatic (67%) and post-infection (0%) infections were lower than pre-COVID-19 volumes by March 2021. There was a slight increase in the proportion of patients with acute endophthalmitis (88.93% vs 86.20%; p=0.76) presenting during the COVID-19 phase as compared to the pre-COVID-19 phase. The proportion of patients requiring inter-state travel showed complete recovery to 107% of pre-COVID-19 distribution by March 2021. Conclusion The first year of the COVID-19 pandemic saw a decline of over half the number of patients with endophthalmitis accessing eye care services. There was an increase in the presentation of endogenous endophthalmitis and a decrease in post-traumatic forms. Patients requiring inter-state travel recovered during the unlock phase.
