O diabetes<\/a> \u00e9 uma doen\u00e7a causadora de uma s\u00e9rie de altera\u00e7\u00f5es na sa\u00fade, como a retinopatia diab\u00e9tica, que, segundo o Minist\u00e9rio da Sa\u00fade, pode acometer at\u00e9 cerca de 35\u201340% dos portadores, dependendo do tempo de doen\u00e7a e do controle glic\u00eamico. A entidade estima que pessoas com diabetes tipo 1 t\u00eam risco maior de desenvolver retinopatia proliferativa a partir de 20 anos de doen\u00e7a e que at\u00e9 90% ter\u00e3o algum grau de retinopatia ao longo da vida. J\u00e1 no tipo 2, o edema macular diab\u00e9tico \u2014 que compromete a regi\u00e3o central da retina \u2014 pode afetar cerca de 20\u201325% dos pacientes ap\u00f3s 15 anos de diagn\u00f3stico. As sociedades m\u00e9dicas promovem a campanha do \u201cNovembro Azul\u201d tamb\u00e9m para alertar sobre os riscos oculares e comorbidades associadas ao diabetes.<\/span><\/p>\n

O grande problema \u00e9 que muitos brasileiros com diabetes sabem da exist\u00eancia da retinopatia diab\u00e9tica e dos riscos, mas n\u00e3o mant\u00eam o h\u00e1bito de consultas peri\u00f3dicas com oftalmologistas para avaliar a sa\u00fade ocular. Estudos nacionais e internacionais apontam que sete em cada dez portadores n\u00e3o realizam exames oculares de rotina, aumentando o risco de perda visual \u2014 algo que seria evit\u00e1vel com acompanhamento regular.<\/span><\/p>\n

Uma pesquisa publicada pela Revista Oftalmol\u00f3gica Brasileira alertou que 80% dos participantes do Programa de Sa\u00fade da Fam\u00edlia (PSF) n\u00e3o conheciam os exames necess\u00e1rios para diagn\u00f3stico e que 65% nunca haviam realizado fundoscopia, exame b\u00e1sico para identificar a doen\u00e7a precocemente.<\/span><\/p>\n

A retinopatia diab\u00e9tica decorre de altera\u00e7\u00f5es nos vasos sangu\u00edneos da retina. Eles podem se tornar tortuosos, perme\u00e1veis ou obstru\u00eddos, prejudicando a circula\u00e7\u00e3o e levando \u00e0 falta de oxig\u00eanio e nutrientes na retina \u2014 camada respons\u00e1vel por captar a luz e convert\u00ea-la em sinais el\u00e9tricos enviados ao c\u00e9rebro.<\/span><\/p>\n

A retina \u00e9 extremamente importante para a vis\u00e3o, pois tem a fun\u00e7\u00e3o de captar a luz e convert\u00ea-la em sinais el\u00e9tricos do nervo \u00f3ptico para o c\u00e9rebro, formando a imagem. A doen\u00e7a est\u00e1 diretamente ligada ao descontrole glic\u00eamico: a glicose elevada compromete os vasos da retina, tornando-os fr\u00e1geis e suscet\u00edveis a vazamentos e obstru\u00e7\u00f5es. O alerta vale para todos com diagn\u00f3stico de diabetes, independentemente do uso de insulina.<\/span><\/p>\n

Quem tem diabetes pode identificar os primeiros sintomas conforme a patologia evolui, apresentando vis\u00e3o emba\u00e7ada, turva ou dupla, percep\u00e7\u00e3o de luzes piscando, halos ao redor das luzes, manchas escuras, pontos flutuantes no campo de vis\u00e3o, dificuldade para perceber cores, aparente vermelhid\u00e3o ocular, press\u00e3o ou dor \u2014 sinais que, sem tratamento, podem levar \u00e0 cegueira.<\/span><\/p>\n

O diagn\u00f3stico requer exame de fundo de olho (fundoscopia) e outros, como a tomografia de coer\u00eancia \u00f3ptica e a angiofluoresceinografia. O m\u00e9dico avalia a presen\u00e7a e gravidade do edema macular e sinais de isquemia ou prolifera\u00e7\u00e3o de vasos anormais.<\/span><\/p>\n

A consulta peri\u00f3dica \u00e9 necess\u00e1ria para essa avalia\u00e7\u00e3o e ainda permite descobrir outras condi\u00e7\u00f5es perigosas e silenciosas, como o glaucoma. Deve-se recordar que retinopatia diab\u00e9tica e diabetes n\u00e3o t\u00eam cura. A recomenda\u00e7\u00e3o \u00e9 o diagn\u00f3stico precoce, tratamento adequado e ado\u00e7\u00e3o de h\u00e1bitos saud\u00e1veis, incluindo atividade f\u00edsica, alimenta\u00e7\u00e3o equilibrada, controle de peso e abandono do cigarro.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
