Salmon patch-associated vitreous hemorrhage in non-proliferative sickle cell retinopathy masquerading as infectious uveitis
To report three cases of non-proliferative sickle cell retinopathy (NPSR) with vitreous hemorrhage masquerading as infectious uveitis.
Three patients were referred from ophthalmologists to our practices with clinical findings suggestive of infectious uveitis. The first patient was referred for new-onset floaters in both eyes, bilateral vitritis and dome-shaped lesions on B-scan ultrasound. He was initially treated for tuberculosis uveitis due to a positive purified protein derivative test. The second patient was referred with floaters and hazy vision in the setting of recent fever and headache and was also reported to have vitritis and unilateral yellow vitreoretinal lesions on fundoscopy. She was initially treated for toxoplasmosis and endogenous endophthalmitis. The third patient presented with flashes, floaters, and decreased vision four months after a ring-enhancing lesion was found on brain imaging, and was found to have unilateral vitritis with yellow vitreoretinal lesions. He was initially started on topical steroids and cycloplegics empirically for uveitis. All patients were ultimately diagnosed as having manifestations of NPSR, including vitreous hemorrhage, and dehemoglobinized salmon patch hemorrhages.
NPSR can occasionally masquerade as infectious uveitis. Obtaining a detailed history with relevant ancillary testing, along with performing a careful physical exam to recognize important clues, can help the physician arrive at the correct diagnosis in these equivocal cases
New York City COVID-19 resident physician exposure during exponential phase of pandemic
© 2020, American Society for Clinical Investigation. 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. Copyright
Vitreoretinal Management and Surgical Outcomes in Proliferative Sickle Retinopathy: A Case Series
PURPOSE: To report the outcomes of current vitreoretinal surgical management of proliferative sickle retinopathy and to compare current methods to previous studies. DESIGN: A retrospective, interventional case series. METHODS: Fifteen eyes of 14 patients with proliferative sickle retinopathy were managed with vitreoretinal surgery over a 12-year period at a single institution. RESULTS: Nine patients had a sickle cell-hemoglobin C (SC) profile, 1 was sickle cell-beta(+) thalassemia (S beta(+)-thal), and 4 were sickle cell trait (AS). All 15 eyes underwent pars plana vitrectomy (PPV): 6 for vitreous hemorrhage (VH), 1 for epiretinal membrane (ERM), and an additional 8 for tractional retinal detachment (RD) and/or rhegmatogenous RD. In addition, an encircling scleral buckle (SB) was used in 2 cases. 20-gauge PPV was used in 7 cases, 23-gauge in 3, and 25-gauge in 5. All 7 eyes with VH or ERM had improved vision postoperatively. Four (50%) of the 8 patients with traction and/or rhegmatogenous RD developed recurrent detachments and required a second operation. All retinas were attached at last follow-up, and visual acuity was 20/400 or better in all eyes. No cases of anterior segment ischemia were encountered. CONCLUSIONS: Anterior segment ischemia is no longer a common occurrence in eyes undergoing surgery for proliferative sickle retinopathy. Although PPV has replaced the use of SB in many situations, an encircling SB may still be used in this population when necessary. Surgery for VH and ERM generally results in favorable outcomes, but eyes undergoing surgery for traction/rhegmatogenous RD carry a more guarded prognosis
