Resumo

Introdução: A toxoplasmose é uma doença causada pelo protozoário intracelular obrigatório, toxoplasma gondii. É uma zoonose cosmopolita e distribuída mundialmente, o ciclo biológico é complexo, e tem três formas importantes: oocisto, taquizoíto e bradizoíto. O felídeo doméstico e silvestre é o hospedeiro definitivo . A contaminação ao homem ocorre através do contato direto com as fezes contaminadas , e a ingestão dos oocistos através da manipulação de alimentos e a forma congênita. Apresenta um quadro clínico variado, desde a infecção assintomática até  manifestações clínicas. Quanto a manifestação ocular,  a uveíte pode ser observada, porém a lesão mais frequente e de alta morbidade é a coriorretinite,  atribuída em até 60% dos pacientes. Objetivo: Neste contexto, sabendo que a toxoplasmose ocular é uma zoonose, este estudo tem como objetivo realizar uma revisão sobre os aspectos gerais como: etiologia, epidemiologia, manifestação ocular, diagnóstico , tratamento e prevenção. Material e Métodos:  Tratou-se de uma pesquisa bibliográfica descritiva para atender os objetivos propostos. Foram analisados leituras de periódicos, revistas, trabalhos e artigos eletrônicos indexados sobre o tema Resultados: Tendo em vista que a  toxoplasmose ocular na população é atribuída a diversos fatores , a hipótese  inicial é devido a intensidade de exposição. Há uma estimativa que 70% a 90% dos pacientes com toxoplasmose congênita e de 10% a 12% de pacientes com infecção pós-natal desenvolvem a doença ocular sempre em forma de retinocoroidite. As características clínicas são : retinitite acometendo a coroide e vítreo e são observados infiltrados de células inflamatórias aderidas a face posterior da córnea . O diagnóstico é feito pelas  manifestações clínicas e laboratoriais. O tratamento é o uso da antibioticoterapia e corticoide. Conclusão: A toxoplasmose ocular tem caráter zoonótico e a forma ocular pode  acarretar a perda da acuidade visual se não tratado. Espera-se que o conhecimento do ciclo biológico , formas profiláticas como : lavagem das mãos após manipulação das fezes do gato doméstico e não ingestão de carnes cruas  , possa diminuir a infecção na forma congênita e que esse levantamento bibliográfico possa contribuir  e abrir novos outros estudos para esclarecer melhores formas de  tratamentos e abordagens para uma maior atenção e assistência a esses pacientes.
