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.

Similar to ultrasound adapting soundwaves to depict the inner structures and tissues, optical coherence tomography (OCT) utilizes low coherence light waves to assess characteristics in the eye. Compared to the previous gold standard diagnostic imaging fluorescein angiography, OCT is a noninvasive imaging modality that generates images of ocular tissues at a rapid speed. Two commonly used iterations of OCT include spectral-domain (SD) and swept-source (SS). Each comes with different wavelengths and tissue penetration capacities. OCT angiography (OCTA) is a functional extension of the OCT. It generates a large number of pixels to capture the tissue and underlying blood flow. This allows OCTA to measure ischemia and demarcation of the vasculature in a wide range of conditions. This review focused on the study of four commonly encountered diseases involving the retina including age-related macular degeneration (AMD), diabetic retinopathy (DR), central serous chorioretinopathy (CSC), and macular telangiectasia (MacTel). Modern imaging techniques including SD-OCT, TD-OCT, SS-OCT, and OCTA assist with understanding the disease pathogenesis and natural history of disease progression, in addition to routine diagnosis and management in the clinical setting. Finally, this review compares each imaging technique’s limitations and potential refinements.

The coronavirus disease 2019 (COVID-19) pandemic has emerged as an unprecedented event that continues to result in deaths worldwide while straining facets of society, including health care delivery.¹ Practice patterns specifically within the field of ophthalmology during the COVID-19 pandemic in the United States have been transformed, with heightened infection control practices²; awareness of relatively high occupational hazard, with adjustments in protection³; redeployment of physicians from typical ophthalmologic duties to floors, intensive care units, and emergency departments³; refitting of operating suites to accommodate COVID-19–only units; and the deferral or delay in routine visits, elective surgical procedures, and screening consultations.^4-6 The changes in the distribution of ophthalmic care represent an effort to minimize the spreading of COVID-19, but with unknown visual consequences for patients.

Cuticular drusen are part of the spectrum of age-related macular degeneration (AMD) with particular clinical and multimodal imaging characteristics. This drusen subpopulation shares several high-risk single nucleotide polymorphisms with AMD. Despite this feature, they can manifest at a relatively young age, presenting with a female preponderance. Multimodal imaging is essential for characterizing such lesions, using a combination of color fundus photographs, optical coherence tomography (OCT), fluorescein angiography (FA), and fundus autofluorescence (FAF). The classic starry-sky pattern visible on FA and the typical central hypoautofluorescent lesion with hyperautofluorescent rim on FAF is considered the result of a central retinal pigment epithelium (RPE) erosion from these triangular elevations of the RPE-basal lamina. This finding may also be responsible for the typical choroidal hypertransmission appreciated through OCT. The clinical course of cuticular drusen may be relatively benign at early stages, with small drusen presenting at a young age. However, the presence of clinical phenotypes characterized by diffuse involvement and/or accompanying large drusen in patients older than 60 years may confer a significant risk for either macular neovascularization or geographic atrophy.

Bilateral diffuse uveal melanocytic proliferation (BDUMP) is a rare and unusual paraneoplastic ocular syndrome with generally poor prognosis. The authors present a case of BDUMP in a patient with bladder cancer, examined with current multimodal imaging. In the clinical setting with drusen and exudative macular detachments, the fundus simulated neovascular age-related macular degeneration, warranting standard-of-care therapy. The imaging actually showed the typical manifestations of BDUMP, but also newly recognized, associated manifestations, including the bacillary layer detachment, a gravitating retinal detachment, and multifocal choroidal hyperpermeability, but no evidence of neovascularization. Recognition of these associated manifestations is of value in appreciating the pathophysiology of this paraneoplastic disorder. Based on the imaging, the correct diagnosis was possible along with a better understanding of the nature of the clinical features in the posterior fundus.

Purpose: To describe the phenotype of CLN-associated retinal dystrophy in a subset of patients at the Columbia University Medical Center, United States, and the Hospital das Clínicas de Pernambuco, Brazil, in comparison to the published literature. Methods: Eleven patients with confirmed biallelic variants in the CLN genes were evaluated via dilated fundus examination, clinical imaging, and full-field electroretinogram. A thorough literature search was conducted to determine previously published variants and associated phenotypes. Results: Genetic testing confirmed the presence of variants in CLN3, CLN7/MFSD8, CLN8, and GRN/CLN11. Five novel variants were identified, and four novel phenotypes of previously published alleles were described. The phenotype differed among patients with variants in the same gene and sometimes among patients with the same allele. Conclusions: Substantial phenotypic variability among variants in the CLN genes makes identification of genotype–phenotype or allele–phenotype correlations challenging. Further study is required to establish an extensive database for adequate patient counseling.
