BACKGROUND. From March 2, 2020, to April 12, 2020, New York City (NYC) experienced exponential growth of the COVID-19 pandemic due to novel coronavirus (SARS-CoV-2). Little is known regarding how physicians have been affected. We aimed to characterize the COVID-19 impact on NYC resident physicians. METHODS. IRB-exempt and expedited cross-sectional analysis through survey to NYC residency program directors April 3–12, 2020, encompassing events from March 2, 2020, to April 12, 2020. RESULTS. From an estimated 340 residency programs around NYC, recruitment yielded 91 responses, representing 24 specialties and 2306 residents. In 45.1% of programs, at least 1 resident with confirmed COVID-19 was reported. One hundred one resident physicians were confirmed COVID-19–positive, with an additional 163 residents presumed positive for COVID-19 based on symptoms but awaiting or unable to obtain testing. Two COVID-19–positive residents were hospitalized, with 1 in intensive care. Among specialties with more than 100 residents represented, negative binomial regression indicated that infection risk differed by specialty (P = 0.039). In 80% of programs, quarantining a resident was reported. Ninety of 91 programs reported reuse or extended mask use, and 43 programs reported that personal protective equipment (PPE) was suboptimal. Sixty-five programs (74.7%) redeployed residents elsewhere to support COVID-19 efforts. CONCLUSION. Many resident physicians around NYC have been affected by COVID-19 through direct infection, quarantine, or redeployment. Lack of access to testing and concern regarding suboptimal PPE are common among residency programs. Infection risk may differ by specialty. FUNDING.

Purpose: The temporary cessation and profound changes in ophthalmic care delivery that occurred as a result of the coronavirus disease 2019 (COVID-19) pandemic have yet to be fully understood. Our objective is to assess patients’ self-reported impact of health care lockdown measures on their fears and anxieties during the crisis period of the COVID-19 pandemic in New York City. Methods: We conducted a digital, self-reported, patient care survey distributed by an e-mail at Columbia University’s Department of Ophthalmology outpatient faculty practice. Inclusion criteria were age greater than or equal to 18 years, a diagnosis of either retinal disease or glaucoma, and a canceled or rescheduled ophthalmology established patient appointment during the acute phase of the COVID-19 pandemic in New York City. Patients without an e-mail address listed in their electronic medical records were excluded. The survey occurred between March 2, 2020, to May 30, 2020. Primary measures were survey responses to assess key areas of patient anxiety or concern during the pandemic including the safety of care delivery in a COVID pandemic, difficulties contacting or being seen by their ophthalmologist, concern of vision loss or disease progression, and concern over missed or access to treatments. Secondary measures were correlating survey response to factors such as visual acuity, intraocular pressure, diagnosis, disease severity, follow-up urgency, recent treatments, and diagnostic testing data. Results: Of the 2594 surveys sent out, 510 (19.66%) were completed. Over 95% of patients were at least as concerned as in normal circumstances about their ocular health during the peak of the pandemic. Overall, 76% of respondents were more concerned than normal that they could not be seen by their ophthalmologist soon enough. Increased concern over ocular health, disease progression, and access to care all showed positive correlations (P<0.05) with worse disease severity as measured with testing such as visual fields and optical coherence tomography. In addition, 55% of patients were afraid of contracting COVID-19 during an office visit. Conclusion and Relevance: We found a majority of our patients were concerned about limitations in access to ophthalmic care and were fearful of disease progression. In addition, we found a number of demographic and clinical factors that correlated with increased anxiety in our patients.

Sickle retinopathy reflects disease-related vascular injury of the eye, which can potentially result in visual loss from vitreous hemorrhage or retinal detachment. Here we review sickle retinopathy among children with sickle cell disease, describe the epidemiology, pediatric risk factors, pathophysiology, ocular findings, and treatment. Newer, more sensitive ophthalmological imaging modalities are available for retinal imaging, including ultra-widefield fluorescein angiography, spectral-domain optical coherence tomography, and optical coherence tomography angiography. Optical coherence tomography angiography provides a noninvasive view of retinal vascular layers that could previously not be imaged and can be quantified for comparative or prospective analyses. Ultra-widefield fluorescein angiography provides a more comprehensive view of the peripheral retina than traditional imaging techniques. Screening for retinopathy by standard fundoscopic imaging modalities detects a prevalence of approximately 10%. In contrast, these more sensitive methods allow for more sensitive examination that includes the retina perimeter where sickle retinopathy is often first detectable. Use of these new imaging modalities may detect a higher prevalence of early sickle pathology among children than has previously been reported. Earlier detection may help in better understanding the pathogenesis of sickle retinopathy and guide future screening and treatment paradigms.
