Impacto da pandemia da COVID-19 sobre transplantes de córnea / Impact of COVID-19 pandemic on corneal transplantations

RESUMO Objetivo: Tendo em vista que o sistema visual representa uma via de contaminação para o novo Corona vírus, a The Global Alliance of Eye Bank Association (GAEBA) divulgou um guideline preconizando a prevenção de transmissão do vírus entre o doadores de tecido ocular e o pacientes receptores, o que resultou em uma diminuição no número de ceratoplastias e aumento de filas de espera para transplantes de córnea (TC) em todo o mundo. Nesse sentido, o presente trabalho tem por objetivo analisar a situação do transplante de córnea (TC) no estado de Alagoas durante o primeiro ano de pandemia da COVID-19. Métodos: Trata-se de um estudo analítico, transversal, observacional utilizando dados provenientes de 3 fontes diferentes: Banco de Tecido Ocular Humano de Alagoas (BTO-AL), Registro Brasileiro de Transplantes (RBT) e Agência Nacional de Vigilância Sanitária (ANVISA). Resultados: Durante os últimos seis anos, foram realizados 284 TCs em Alagoas, segundo dados do Banco de Transplante de Olhos do estado (BTO), já segundo a Registro Brasileiro de Transplantes (RBT) foram realizados 451 TCs. A porcentagem de córneas não oriundas do BTO de Alagoas se mostrou crescente até 2019, porém decresceu em 2020, e no primeiro ano de pandemia , apenas 11,66% da necessidade anual estimada foi atendida, sendo o período com menor número de TCs realizados entre os seis anos analisados na pesquisa. Conclusão: O estudo demonstra o declínio na doação e realização de transplantes de córnea durante o primeiro ano da pandemia da COVID-19 em Alagoas.

ABSTRACT Objective: Considering the visual system is one source of contamination for the new coronavirus, The Global Alliance of Eye Bank Association (GAEBA) released a guideline recommending prevention of virus transmission between eye tissue donors and recipients, which resulted in a reduction of keratoplasties and increase in the waiting lists for corneal transplants worldwide. Hence, this work aims to analyze the situation of corneal transplantation in the state of Alagoas, during the first year of COVID-19 pandemic. Methods: This is an analytical, cross-sectional, observational study using data from 3 different sources: Human Eye Tissue Bank of Alagoas (BTO-AL), Brazilian Transplant Registry (RBT) and National Health Surveillance Agency (ANVISA). Results: During the past six years, 284 corneal transplants were performed in Alagoas, according to data from the Eye Transplant Bank (BTO) of the state, whereas according to the Brazilian Transplant Registry (RBT) 451 corneal transplants were performed. The percentage of corneas not coming from the BTO of Alagoas increased until 2019 but dropped in 2020. In the first year of the pandemic, only 11.66% of estimated annual need was met, and this period had the lowest number of corneal transplants performed out of the six years analyzed in the research. Conclusion: The study demonstrated the decline in donation and performance of corneal transplants during the first year of the COVID-19 pandemic in Alagoas.

Olho seco e COVID-19: uma revisão narrativa / Dry eyes and COVID-19: a narrative review

RESUMO Com o advento do cenário pandêmico causado pelo SARS-CoV-2, no início do ano de 2020, foi notado um vasto quadro clínico entre os indivíduos infectados. Dentre os sintomas oculares mais comuns ocasionados pela COVID-19, o olho seco tornou-se bastante prevalente nesse meio. O estudo do tipo revisão narrativa busca avaliar os fatores de risco associados ao surgimento ou à intensificação dos quadros de olho seco na população durante o período pandêmico. A partir da análise bibliográfica, foi descrita a influência da ventilação por pressão positiva, do uso de máscaras de forma incorreta e de telas eletrônicas e da ansiedade e da depressão como fatores predisponentes ao desenvolvimento da doença do olho seco. No entanto, ainda é notada a necessidade de estudos mais explicativos para estabelecer a relação direta entre a causalidade dos fatores.

ABSTRACT With the advent of the pandemic scenario caused by SARS-CoV-2 in the beginning of the year 2020, a vast clinical picture was noticed among the infected individuals. Among the most common eye symptoms caused by Covid-19, dry eye (DE) has become quite prevalent in this environment. The narrative review study seeks to assess the risk factors associated with the emergence or intensification of DE conditions in the population during the pandemic period. A literature review showed the influence of positive pressure ventilation, incorrect use of masks, as well as electronic screens, in addition to anxiety and depression as predisposing factors for the development of dry eye disease. However, the need for more explanatory studies and for establishing a direct relationship between the causality of the factors is still noted.

Depression and dry eye: a narrative review.

Dry eye disease (DED) is a multifactorial disease affecting tear quality and/or production and eye surface and is one of the most common eye disorders found in clinical practice. The association between psychiatric disorders and dry eye has been the subject of several studies since patients with this syndrome present a tendency toward a depressive mood. This narrative review aims to demonstrate the relationship between depression and DED, which is due to the side effects of psychotropic drugs or the tendency of the low pain threshold of the depressive patient. The work was produced from the analysis of 13 articles published during the last decade on this subject and demonstrated that the depressive state is linked to the appearance or worsening of DED resulting from chronic eye pain. Also, the treatment of depression with selective inhibitors of serotonin receptors causes inflammatory cytokine secretion with subsequent inflammation and apoptosis of cells on the ocular surface. The need for new studies on optimization of psychiatric treatment in patients with ophthalmic diseases, such as DED, was verified, aiming at the relief of symptoms and the reduction of psychological and eye damage caused by them.

Viagem espacial: Um desafio sob o ponto de vista da oftalmologia / Space travel: A challenge from the point of view of ophthalmology

RESUMO No final do século vinte, com o surgimento de novas tecnologias e de novos programas espaciais, a medicina aeroespacial ganhou destaque no meio científico uma vez que os estudos relacionados às alterações da fisiologia humana no espaço tornaram-se cada vez mais necessário para a manutenção da saúde de cosmonautas. Os olhos são considerados uma das estruturas mais sensíveis do corpo às alterações vasculares, estruturais e bioquímicas provocadas pela microgravidade e radiação cósmica. Nesse sentido, essa revisão narrativa busca identificar e explicar as principais alterações morfológicas e funcionais que ocorrem no sistema visual em decorrência de missões espaciais.

ABSTRACT At the end of the twentieth century, with the emergence of new technologies and new space programs, aerospace medicine gained prominence in the scientific community since studies related to changes in human physiology in space have become increasingly necessary for the maintenance of cosmonaut health. The eyes are considered one of the most sensitive structures in the body to vascular, structural and biochemical changes caused by microgravity and cosmic radiation. In this sense, this narrative review seeks to identify and explain the main morphological and functional changes that occur in the visual system as a result of space missions.

Ocular manifestations of COVID-19: a literature review.

Coronavirus disease 2019 (COVID-19) caused by the highly pathogenic SARS-Cov-2 virus, was declared as a pandemic by the World Health Organization (WHO) in March 2020. Its main clinical manifestations are related to airway involvement; however, there is extrapulmonary impairment in some cases. Given this context, this literature review aims to identify the ophthalmological conditions caused by infection with the novel coronavirus. Although ocular findings do not include the standard clinical presentation of the disease, there are reports of some ophthalmological changes in COVID-19 patients, and conjunctivitis is the most common among these.
