COVID-19 pandemic decreased the ophthalmic outpatient numbers and altered the diagnosis distribution in a community hospital in Taiwan: An observational study

Glaucoma progression due to refraining examination amid the pandemic of COVID-19

PURPOSE

Some patients refrained from seeking an ophthalmologist due to the anxiety and morbidity associated with the coronavirus disease (COVID-19) pandemic. We investigated progressive visual field defects in patients with glaucoma who refrained from ophthalmological examinations.

METHODS

This was a retrospective study. We analyzed data from 886 patients with glaucoma who visited Inouye Eye Hospital in June 2022 and were followed-up prior to January 2020. We examined the number of times patients canceled visits between January 2020 and May 2022 due to coronavirus concerns. We assessed the mean deviation (MD) values of the Humphrey Visual Field Assessment (HFA) program 30-2 SITA Standard values after visit interruptions for worsening beyond the MD values predicted by the MD slope. Factors influencing this difference were analyzed using logistic regression analysis.

RESULTS

The study included 374 men and 512 women. The mean age was 68.7 ± 12.0 years. Visit interruptions occurred in 146 patients (16.5%), with 95 (65.1%) rescheduling once, 27 (18.5%) twice, and 24 (16.4%) three or more times. Among 90 patients who underwent HFA regularly, 50 (55.6%) experienced worse-than-expected MD values and 12 (13.3%) deteriorated by 2 dB or more. Longer interruptions and high intraocular pressure before interruption worsened the MD values by 2 dB or more.

CONCLUSION

Patients with glaucoma with visit interruptions due to the pandemic should be monitored for the progression of visual field impairment.

Clinical Characteristics and Outcomes of Endophthalmitis Before and During the COVID-19 Pandemic

Purpose

To evaluate the clinical characteristics and visual acuity outcomes of patients who presented with endophthalmitis prior to and during the coronavirus disease 2019 (COVID-19) pandemic.

Methods

This multicenter retrospective case series with historical controls included consecutive patients presenting with any form of endophthalmitis from March 1, 2019 to September 1, 2019 (pre-COVID-19) and from March 1, 2020 to September 1, 2020 (COVID-19) at Mayo Clinic Rochester (MCR), Health System (MCHS), Arizona (MCA), and Florida (MCF) sites. Cases were divided into "pre-COVID-19" versus "COVID-19" groups depending on when they first presented with endophthalmitis.

Results

Twenty-eight cases of endophthalmitis presented to all Mayo Clinic sites during the study period. Of these, 10 patients presented during the first six months of the COVID-19 pandemic. During the same six-month period the year prior, 18 patients presented with endophthalmitis. Endophthalmitis etiology (post-injection, post-cataract extraction, post-glaucoma filtering surgery, post-pars plana vitrectomy, endogenous, and others) was similar between both groups (P = 0.34), as was post-injection endophthalmitis rate (P = 0.69), days to presentation (P = 0.07), initial management (P = 0.11), culture-positivity rate (P = 0.70), and need for subsequent pars plana vitrectomy (P = 1). Visual acuity outcomes were similar between both groups at six months, however, the mean LogMAR visual acuity at presentation was worse in the COVID-19 group compared to the pre-COVID-19 group (2.44 vs 1.82; P = 0.026).

Conclusion

Clinical characteristics and the post-injection endophthalmitis rate were similar during both periods, however, patients presented with worse vision during the pandemic suggesting that the pandemic may have contributed to delayed presentation, regardless, outcomes are still poor.

Impact of COVID-19 on glaucoma management: A review

Glaucoma is the leading cause of irreversible vision loss and the second leading cause of blindness worldwide. The rapid transmission of SARS-CoV-2virus compelled governments to concentrate their efforts on emergency units to treat the large number of cases that arose due to the Covid-19 outbreak. As a result, many chronically ill patients were left without access to medical care. The progression of glaucoma in previously diagnosed cases has been accelerated; due to this, some have lost their vision. Evaluation of Covid-19's effect on glaucoma treatment was one goal of this study. We used search phrases like "COVID-19," "telemedicine," and "glaucoma" to find published papers on COVID-19 and glaucoma. Artificial Intelligence (AI) may be the answer to the unanswered questions that arose due to this pandemic crisis. The benefits and drawbacks of AI in the context of teliglaucoma have been thoroughly examined. These AI-related ideas have been floating around for some time. We hope that Covid-19's enormous revisions will provide them with the motivation to move forward and significantly improve services. Despite the devastation the pandemic has caused, we are hopeful that eye care services will be better prepared and better equipped to avoid the loss of sight due to glaucoma in future.
