Purpose : Coronavirus disease (COVID-19) has escalated to a global pandemic with increasing reports of ophthalmic disease. We report ophthalmic observations of hospitalized COVID-19 patients and correlate retinal disease findings with clinical and laboratory data. Methods : Retrospective review of COVID-19 patients who underwent ophthalmic exam during hospitalization within Emory Healthcare between April-July 2020. Results : Thirty-seven patients were examined with 23 (62%) females and a mean age of 54 years. 35 patients were admitted to the ICU. Ophthalmic manifestations included conjunctival injection in 12 eyes (17%), chemosis in 8 (11%) and retinopathy in 20 eyes (27%) with bilateral retinopathy in 6 patients (16%). No difference in baseline comorbidities or COVID-19 complication development was observed between patients with and without retinopathy. However, patients with retinopathy required ICU care for 1 week longer than those without retinopathy (27.6 vs 19.9 days p=0.19). The mean sequential organ failure assessment score at ICU admission was 6.18. All patients with retinopathy required both mechanical ventilation and vasopressors, while in patients without retinopathy, 15 (65%) and 12 (52%) required mechanical ventilation and vasopressors respectively (p=0.015, p=0.002). 6 patients with retinopathy required extracorporal membrane oxygenation compared to 1 without retinopathy (p=0.0070). While the mean peak D-Dimer was elevated at 18477, in the entire cohort, the peak D-Dimer was higher in patients with retinopathy (28,971 vs 12,575, p=0.0298). The fibrinogen nadir during hospitalization was on average 338 for the entire cohort, and reduced in patients with retinopathy (262 vs 381, p=0.029). Peak D-dimer analyses with a threshold of 16,508 showed an odds ratio of 16.7 (95% CI 3.11-89.3) for retinopathy. Fibrinogen nadir with a threshold of 367 showed odds ratio of 0.06 (95% CI 0.01-0.53) with 0.75 concordance. Conclusions : Retinopathy was the most common ophthalmic manifestation in a critically ill COVID-19 population, exceeding 25% of patients. Elevated D-dimers and a lower fibrinogen nadir in patients with retinopathy suggest a pathogenic relationship between coagulation pathways and retinal microangiopathy.

A health care crisis such as the coronavirus disease 2019 (COVID-19) pandemic requires allocation of hospital staff and resources on short notice. Thus, new and sometimes less experienced team members might join the team to fill in the gaps. This scenario can be particularly challenging in endovascular stroke treatment, which is a highly specialized task that requires seamless cooperation of numerous health care workers across various specialties and professions. This document is intended for stroke teams who face the challenge of integrating new team members into endovascular stroke-treatment workflows during the COVID-19 pandemic or any other global health care emergency. It discusses the key strategies for smooth integration of new stroke-team members in a crisis situation: 1) transfer of key knowledge (simple take-home messages), 2) open communication and a nonjudgmental atmosphere, 3) strategic task assignment, and 4) graded learning and responsibility. While these 4 key principles should generally be followed in endovascular stroke treatment, they become even more important during health care emergencies such as the COVID-19 pandemic, when health care professionals have to take on new and additional roles and responsibilities in challenging working environments for which they were not specifically trained.
