Impact of 5 waves of COVID-19 on pediatric ophthalmology.

OBJECTIVE

To characterize the impact of multiple waves of COVID-19 on pediatric ophthalmology at a tertiary care hospital.

METHODS

Medical records were reviewed from pediatric patients seen for ophthalmic emergencies at the Montreal Children's Hospital (Montreal, Canada) from 5 COVID-19 periods: March 13 to May 31, 2020; September 20, 2020, to February 21, 2021; March 21 to May 31, 2021; August 17 to November 5, 2021; and December 19, 2021, to January 25, 2022, as well as 2 pre-COVID time periods: March 13 to May 31, in 2018 and 2019).

RESULTS

There was a significant reduction in ophthalmic consultations when comparing pre-COVID to all 5 COVID waves (p < 0.0001). There was an increase in the average number of daily urgent (p = 0.01) ophthalmic consultations from waves 1 to 4. Mean household income of patients was not significantly different pre-COVID compared to during the 5 COVID waves (p = 0.96). The most common referral reason was ocular trauma (38.0% of cases). There was a non-significant trend demonstrating more infectious disease presentations during waves 3 to 5 (p = 0.07). There was no difference in symptom duration prior to presentation (p = 0.54); however, there was a difference in the time between emergency room and ophthalmology assessment in waves 3 and 4 compared with wave 5 (p = 0.003).

CONCLUSION

The number of pediatric ophthalmology consultations was less during the 5 COVID waves than pre-COVID. An increase in urgent pediatric ophthalmology consultations occurred as COVID-19 infection rates in Quebec decreased. Access to health care and time to care were preserved across waves compared with pre-pandemic.
