A janeiro de 2026<\/a> A edi\u00e7\u00e3o de 2009 da Cataract & Refractive Surgery Today apresenta uma discuss\u00e3o reflexiva baseada em casos, examinando como a gest\u00e3o do ceratocone precoce evoluiu nos \u00faltimos anos. O artigo contrasta a tomada de decis\u00f5es cl\u00ednicas em 2018 com a pr\u00e1tica contempor\u00e2nea, destacando como os avan\u00e7os no diagn\u00f3stico e nas estrat\u00e9gias de cross-linking corneano (CXL) remodelaram os limiares de tratamento - particularmente em pacientes pedi\u00e1tricos e adolescentes.<\/p>\n

<\/p>\n

<\/p>\n

Entre os colaboradores encontra-se Prof. Farhad Hafezi, MD, PhD, FARVO<\/a>, Diretor m\u00e9dico do Instituto ELZA, cuja sec\u00e7\u00e3o se centra na identifica\u00e7\u00e3o precoce e no tratamento atempado de queratocone<\/a> em crian\u00e7as. Com base na experi\u00eancia cl\u00ednica a longo prazo e nos dados pedi\u00e1tricos publicados, o Prof. Hafezi salienta que os doentes jovens apresentam um elevado risco de progress\u00e3o r\u00e1pida da doen\u00e7a, muitas vezes antes de serem cumpridos os crit\u00e9rios convencionais de progress\u00e3o documentada.<\/p>\n

<\/p>\n

<\/p>\n

O caso discutido envolve um paciente de 12 anos de idade com sinais tomogr\u00e1ficos iniciais de ceratocone e paquimetria corneana fina. Em 2018, o tratamento baseou-se na tomografia de Scheimpflug e na avalia\u00e7\u00e3o biomec\u00e2nica, com uma prefer\u00eancia pelo CXL padr\u00e3o sem epit\u00e9lio para alcan\u00e7ar o fortalecimento m\u00e1ximo da c\u00f3rnea. Desde ent\u00e3o, as melhorias na resolu\u00e7\u00e3o do diagn\u00f3stico - particularmente o mapeamento da espessura epitelial utilizando OCT do segmento anterior - permitiram uma dete\u00e7\u00e3o mais precoce e mais segura da atividade da doen\u00e7a.<\/p>\n

<\/p>\n

<\/p>\n

No artigo do CRST, o Prof. Hafezi descreve como a gest\u00e3o atual seria diferente. Hafezi descreve o tratamento atual que seria diferente. No caso de doen\u00e7a precoce ou subcl\u00ednica, podem ser selecionados protocolos CXL acelerados menos invasivos para o epit\u00e9lio, que oferecem uma efic\u00e1cia biomec\u00e2nica compar\u00e1vel \u00e0 das abordagens convencionais, reduzindo simultaneamente os encargos para o doente. No caso de doen\u00e7a mais avan\u00e7ada, s\u00e3o discutidos protocolos de CXL acelerado de alta flu\u00eancia que fornecem energia total acrescida ao longo de tempos de tratamento mais curtos, como forma de obter um endurecimento da c\u00f3rnea equivalente ao de Dresden.<\/p>\n

<\/p>\n

<\/p>\n

Uma mensagem central do artigo \u00e9 a mudan\u00e7a da interven\u00e7\u00e3o tardia para o tratamento imediato ap\u00f3s o diagn\u00f3stico do ceratocone pedi\u00e1trico. Esta mudan\u00e7a reflecte a evid\u00eancia acumulada de que esperar pela progress\u00e3o documentada em doentes jovens resulta frequentemente em perda visual evit\u00e1vel. O segundo consenso global sobre o ceratocone, referido na discuss\u00e3o, apoia esta estrat\u00e9gia proactiva, sendo que a maioria dos especialistas em c\u00f3rnea recomenda agora o CXL precoce em crian\u00e7as.<\/p>\n

<\/p>\n

<\/p>\n

A contribui\u00e7\u00e3o na Cataract & Refractive Surgery Today ilustra a forma como a gest\u00e3o do ceratocone passou de protocolos uniformes para uma sele\u00e7\u00e3o de tratamento optimizada e individualizada com base na idade, fase da doen\u00e7a e carater\u00edsticas da c\u00f3rnea.<\/p>\n
