O medo de efeitos colaterais, inclusive como eles podem afetar a visão, é classificado como o motivo principal pelo qual alguns americanos permanecem hesitantes em ser vacinados contra o vírus que causa a COVID-19. No entanto, ainda não surgiu nenhuma evidência de que quaisquer efeitos colaterais generalizados a partir das vacinas estejam relacionados à visão.
É importante observar, porém, que ao menos um incidente isolado de efeito colateral relacionado aos olhos foi relatado – um profissional da saúde nos EUA que apresentou inchaço nos olhos após receber uma injeção para a COVID-19. As organizações de segurança locais estão investigando isso, entre outras reações alérgicas raras à vacina para o coronavírus produzida pela Pfizer e pela BioNTech.
Outros efeitos colaterais causados pela vacina Pfizer/BioNTech são ”principalmente leves a moderados”, de acordo com um relatório publicado pela World Health Organization (WHO), Organização Mundial da Saúde, OMS.
Quando efeitos colaterais ocorreram entre os participantes, as reações mais comuns foram:
- sintomas no local da injeção, inclusive dor, inchaço e vermelhidão.
- sintomas sistêmicos como fadiga, dor muscular, calafrios, dor nas articulações e febre.
- outros sintomas, como dor de cabeça e náuseas.
Um relatório da OMS sobre a vacina para COVID-19 da Moderna relatou efeitos colaterais semelhantes.
Os profissionais da saúde ocular respondem à COVID-19
Os possíveis efeitos colaterais não estão impedindo os profissionais da saúde ocular de receber suas vacinas para COVID-19 e, em alguns casos, até administrá-las eles próprios.
Em muitas partes do mundo, os oftalmologistas e sua equipe estão sendo tratados como grupos de alta prioridade para vacinação.
Nas diretrizes publicadas pelo College of Optometrists no Reino Unido, a organização declara: “Os profissionais da saúde ocular seriam tratados como trabalhadores na linha de frente nos setores de assistência social e da saúde, listados como o segundo grupo de maior prioridade no programa de vacinação.”
Quando disponíveis, essas vacinações antecipadas protegerão os profissionais da saúde ocular e seus pacientes, diminuindo ou interrompendo a transmissão viral em suas práticas.
Os oftalmologistas nos EUA também estão engajados na luta contra o COVID-19.
O Dr. William Culbertson, professor de oftalmologia do Bascom Palmer Eye Institute em Miami, EUA, disse ao Ophthalmology Times que os oftalmologistas e funcionários do instituto começaram a receber vacinas em 15 de dezembro de 2020.
“Embora não sejamos profissionais da saúde da linha de frente, todos nós ficamos bem próximos aos pacientes na lâmpada de fenda e em cirurgias, por isso corremos um risco substancial até sermos vacinados,” disse Culbertson.
Adicionalmente, ao menos um oftalmologista – o Dr. Jorge Arroyo do Beth Israel Deaconess Medical Center, em Boston, EUA – participou do estudo da vacina da Moderna para COVID-19. E foi um oftalmologista chinês que, em dezembro de 2019, alertou o mundo sobre o que viria a ser conhecido como COVID-19; a doença acabou causando sua morte.
Problemas oculares em crianças com COVID-19
Embora as vacinas para COVID-19 não tenham sido associadas a problemas graves de visão, os pesquisadores detectaram problemas oculares em várias crianças com a própria doença. Um estudo mostrou quase um quarto das crianças em um hospital chinês que foram tratadas em janeiro, fevereiro e março de 2020 para COVID-19 desenvolveu problemas oculares leves. Esses problemas incluíram secreção ocular associada a conjuntivite (olho vermelho), coceira nos olhos, dor nos olhos e inchaço das pálpebras.
Mas o estudo foi limitado. Os pesquisadores analisaram as doenças de somente 216 pacientes pediátricos.
Problemas oculares relacionados a outras vacinas
Embora as vacinas para COVID-19 não tenham causado, até agora, efeitos colaterais preocupantes relacionados à visão, vacinas para várias outras doenças têm sido associadas a problemas na visão e oculares. Aqui está um resumo desses problemas:
Vacina contra a gripe sazonal
Em casos raros, alguns pacientes que receberam a vacina contra a gripe apresentaram sintomas leves como vermelhidão nos olhos, dor nos olhos e visão embaçada.
Os efeitos colaterais comuns da vacina contra a gripe incluem dor, vermelhidão ou inchaço no local da injeção, juntamente com dor de cabeça, febre, náuseas e dores musculares.
Vacina para sarampo-caxumba-rubéola (measles-mumps-rubella, MMR)
Um estudo publicado em 2008 concluiu que a neurite óptica é uma complicação rara da vacina para sarampo-rubéola (measles-rubella, MR). A neurite óptica é uma inflamação que afeta o nervo óptico e envia sinais da parte de trás do olho para o cérebro.
Efeitos colaterais comuns da vacina para MMR incluem febre, erupção cutânea leve, bochecha ou glândulas do pescoço inchadas e dor temporária nas articulações (principalmente em mulheres adolescentes e adultas). Efeitos colaterais raros incluem convulsões de curto prazo e baixa contagem de plaquetas. Em casos extremamente raros, a vacina para MMR pode causar surdez, convulsões de longo prazo, coma ou lesão cerebral.
Vacinas contra varicela e herpes zóster
Um estudo encontrou casos raros de inflamação da córnea em crianças (varicela) e adultos (herpes zóster) após terem recebido a vacina para o vírus zóster para ambas as doenças.
Efeitos colaterais comuns da vacina para varicela incluem braço dolorido e erupção cutânea leve no local da injeção, dor e rigidez temporária nas articulações e febre. Para a vacina para herpes zóster, os efeitos colaterais comuns são braço dolorido, vermelhidão e inchaço no local da injeção, cansaço, dores musculares, dor de cabeça, calafrios, febre, dor de estômago e náusea.
O sarampo pode causar problemas nos olhos
Em todo o mundo, o sarampo causa até 60.000 casos de cegueira a cada ano, de acordo com a American Academy of Ophthalmology (AAO). Outros problemas de visão potenciais associados ao sarampo incluem:
- Olhos lacrimejantes e vermelhos acionados por olho vermelho (conjuntivite)
- Ceratite, uma infecção da córnea
- Lesão na córnea
- Retinopatia, que danifica a retina e pode levar à perda temporária ou permanente da visão
- Neurite óptica
- Cegueira infantil
A vacina contra o sarampo é a melhor opção para prevenir a doença e, portanto, prevenir problemas na visão relacionados ao sarampo.
A vacina para herpes zóster pode prevenir problemas na visão
A AAO recomenda que pessoas com 50 anos de idade ou mais tomem a vacina contra herpes zóster para prevenir uma “complicação extremamente dolorosa e desfigurante” chamada herpes zóster oftálmico, que pode causar cegueira.
Se o vírus do herpes zóster infectar os nervos do olho, a AAO diz que isso pode levar a:
- Erupção na pálpebra
- Infecção ocular
- Conjuntivite (olho vermelho)
- Infecção e inflamação da córnea
- Visão embaçada
- Sensibilidade a luzes brilhantes
- Dor e inchaço dentro do olho
- Inchaço do nervo óptico atrás do olho
- Ruptura da córnea requerendo transplante de córnea
Na verdade
embora várias vacinas possam causar efeitos colaterais, principalmente leves, relacionados à visão, não há evidências científicas de que as vacinas para COVID-19 desencadeiem efeitos colaterais relacionados aos olhos. Os especialistas dizem que os benefícios de ser vacinado contra a COVID-19 superam os efeitos colaterais em potencial.

It’s difficult to find educated people on this topic, but you sound like
you know what you’re talking about! Thanks
I’m gone to convey my little brother, that he should
also visit this weblog on regular basis to take updated from newest news update.
Wonderful blog! I found it while searching on Yahoo News.
Do you have any tips on how to get listed in Yahoo News? I’ve been trying for a while
but I never seem to get there! Thank you
Asking questions are truly good thing if you
are not understanding something completely, but this
article gives nice understanding even.
Hello everyone, it’s my first go to see at this site, and article is actually fruitful for
me, keep up posting these types of posts.
This is really interesting, You’re a very skilled blogger.
I have joined your feed and look forward to seeking more of your excellent post.
Also, I have shared your website in my social networks!
I used to be able to find good info from your content.
Very energetic blog, I loved that bit. Will there be a part 2?
I have been surfing online more than three hours today, yet I never
discovered any fascinating article like yours.
It is lovely value enough for me. In my view, if all website owners and bloggers made
just right content as you did, the web will likely be much more helpful than ever before.
I’m really enjoying the theme/design of your blog. Do you
ever run into any browser compatibility issues? A number of my blog audience have complained about my blog not working correctly
in Explorer but looks great in Firefox. Do you have any
tips to help fix this problem?
I think everything posted made a lot of sense. However, think
about this, suppose you typed a catchier post title?
I am not saying your content is not solid., but what if you added
a title to maybe grab people’s attention? I mean A vacina para COVID-19:
Isso afetará sua visão? – Lucas Tavares Faria is a little boring.
You should glance at Yahoo’s front page and see how they create news headlines to get viewers to click.
You might try adding a video or a picture or two to
grab people interested about what you’ve got
to say. In my opinion, it could make your posts a little livelier.
Ridiculous quest there. What happened after? Good luck!
I know this if off topic but I’m looking into starting my own blog and was curious what all is required to get set
up? I’m assuming having a blog like yours would cost a pretty penny?
I’m not very internet savvy so I’m not 100% positive. Any recommendations or advice would be greatly appreciated.
Cheers
