Summary Renal impairment is common in patients who are critically ill with coronavirus disease‐19 (COVID‐19). We examined the association between acute and chronic kidney disease with clinical outcomes in 372 patients with coronavirus disease‐19 admitted to four regional intensive care units between 10 March 2020 and 31 July 2020. A total of 216 (58%) patients presented with COVID‐19 and renal impairment. Acute kidney injury and/or chronic kidney disease was associated with greater in‐hospital mortality compared with patients with preserved renal function (107/216 patients (50%) (95%CI 44–57) vs. 32/156 (21%) (95%CI 15–28), respectively; p < 0.001, relative risk 2.4 (95%CI 1.7–3.4)). Mortality was greatest in patients with renal transplants (6/7 patients (86%) (95%CI 47–100)). Mortality rates increased in patients with worsening renal injury according to the Kidney Disease: Improving Global Outcomes classification: stage 0 mortality 33/157 patients (21%) (95%CI 15–28) vs. stages 1–3 mortality 91/186 patients (49%) (95%CI 42–56); p < 0.001, relative risk 2.3 (95%CI 1.7–3.3). Survivors were less likely to require renal replacement therapy compared with non‐survivors (57/233 patients (24%) vs. 64/139 patients (46%), respectively; p < 0.001, relative risk 1.9 (95%CI 1.4–2.5)). One‐fifth of survivors who required renal replacement therapy acutely in intensive care continued to require renal support following discharge. Our data demonstrate that renal impairment in patients admitted to intensive care with COVID‐19 is common and is associated with a high mortality and requirement for on‐going renal support after discharge from critical care. Our findings have important implications for future pandemic planning in this patient cohort.

In this cross-sectional study, we investigate the presence of Severe Acute Respiratory Syndrome Coronavirus 2 Ribonucleic Acid (SARS-CoV-2 RNA) in the tears of hospitalized COVID-19 patients. After laboratory confirmation of SARS-CoV-2 infection by reverse transcription polymerase chain reaction (RT-PCR) analysis, tear samples from both eyes of each patient were collected using conjunctival swab for RT-PCR. Detailed demographic profile, systemic and ocular symptoms, comorbidities, clinical, ancillary, and ocular manifestations were evaluated. Of the 83 patients enrolled in the study, 7 (8.43%) had SARS-CoV-2 RNA detected in the tear samples. Neutrophils’ count, C-reactive protein, and D-dimer were higher in patients with SARS-CoV-2 detected in tears than in patients without virus in ocular surface samples. One patient with SARS-CoV-2 in tears showed mild ocular eyelid edema, hyperemia, and chemosis. No relevant ocular manifestations were detected in the other patients. Although the levels of viral RNA on ocular surface samples were low for most patients (5/7), with positivity only for gene N and CT higher than 30, two patients were positive for all viral targets tested ( N, E, and RpRd), with viral load near 1 × 105 ePFU/mL, indicating that the ocular transmission of SARS-CoV-2 is a possibility that needs to be considered, especially in the hospital environment. Further studies need to be conducted to demonstrate whether infective viral particles could be isolated from tears.

A oclusão arterial retiniana aguda é uma causa clássica de redução monocular súbita e indolor da acuidade visual. É um tipo de acidente vascular encefálico que tem fatores de risco e mecanismos etiológicos em comum com a isquemia cerebral aguda. O oftalmologista tem um papel essencial no diagnóstico desta patologia, através de exames físicos e propedêutica complementar. Neste artigo, relatamos um caso de oclusão de um ramo da artéria retiniana afetando a hemirretina no olho direito de uma mulher de 79 anos sem comorbidades conhecidas. Os tratamentos atuais da isquemia aguda ainda apresentam baixa eficácia. No entanto, o diagnóstico rápido e preciso permite o estabelecimento de métodos de prevenção secundária, a fim de evitar novos eventos isquêmicos e cardiovasculares potencialmente fatais.

RESUMOO glaucoma é uma neuropatia óptica crônica que figura como a principal causa de cegueira irreversível no mundo. Um dos métodos cirúrgicos disponíveis atualmente para o seu tratamento é o implante da válvula de Ahmed, dispositivo capaz de realizar um shunt entre a câmara anterior e a região subconjuntival, desviando o fluxo do humor aquoso e, consequentemente, gerando redução da pressão intraocularo único parâmetro modificável na progressão da doença. Este trabalho descreve um caso de extrusão espontânea da válvula de Ahmed implantada em região nasal inferior. Trata-se de uma complicação rara deste tipo de implante, ocorrido no 60 o dia de pós-operatório, não desencadeada por trauma ocular ou outros fatores. O número de cirurgias oculares prévias é uma condição que pode ter contribuído para a ocorrência da extrusão. A identificação e o tratamento adequado de tais complicações auxiliam na redução de possíveis infecções secundárias à extrusão, como a endoftalmite.
