Impact of COVID-19 on ophthalmic medical access during successive waves: Demographics, disease factors, and wave locations.

BACKGROUND

The coronavirus disease (COVID-19) pandemic significantly impacted medical care, including ophthalmology. This study aimed to identify factors associated with reduced ophthalmic medical access during the pandemic.

METHODS

This nationwide population-based cohort study analysed South Korean health insurance claims data from January 2019 to November 2021. Outpatient visits and surgeries for age-related macular degeneration, cataract, diabetic retinopathy, glaucoma, and retinal detachment during the two pandemic waves were compared with those in the non-pandemic period. Poisson regression was used to estimate incidence rate ratios and changes in outpatient visits and surgeries between waves concerning patient age, sex, residential location, and health insurance type.

RESULTS

Outpatient visits for five eye diseases decreased in the first wave (0.733-0.985, P < 0.001). In the second wave, only outpatient visits for age-related macular degeneration, cataract, and glaucoma decreased (0.754, 0.878, and 0.874, respectively, all P < 0.001). Age-related macular degeneration, cataract, and glaucoma surgeries were significantly reduced in the first wave (0.829, P < 0.001; 0.836, P < 0.001; 0.904, P = 0.030, respectively). Age-related macular degeneration (0.852) and cataract (0.716) surgeries dropped in the second wave. Women and elderly (>65 years) patients curtailed outpatient visits and surgeries more throughout the pandemic and were less resilient during the second wave. Wave location was also related to outpatient visits and surgeries.

CONCLUSIONS

The COVID-19 pandemic decreased outpatient visits and surgeries for eye diseases, with more significant impact on women, older patients, and those residing near wave locations. These findings can inform healthcare policies to minimise future pandemic impacts on healthcare delivery.
