Studies show that 50% of children with multiple disabilities have some visual impairment, and 4% of all children are diagnosed with strabismus. The strabismus is an eye disability associated with handling capacity of the eye, defined as any deviation from perfect ocular alignment. Besides of aesthetic aspect, the child may report blurred or double vision . Ophthalmological cases not diagnosed correctly are reasons for many school abandonments. The Ministry of Education of Brazil points to the visually impaired as a challenge to the educators of children, particularly in literacy process. The traditional eye examination for diagnosis of strabismus can be accomplished by inducing the eye movements through the doctor s instructions to the patient. This procedure can be played through the computer aided analysis of images captured on video. This paper presents a proposal for distributed system to assist health professionals in remote diagnosis of visual impairment associated with motor abilities of the eye, such as strabismus. It is hoped through this proposal to contribute improving the rates of school learning for children, allowing better diagnosis and, consequently, the student accompaniment / A vis?o ? um dos cinco sentidos do corpo humano e, em crian?as, ? respons?vel por at? 80% da percep??o do mundo ao redor. Estudos revelam que 50% das crian?as com m?ltiplas defici?ncias possuem alguma defici?ncia visual, sendo que 4% de todas as crian?as s?o diagnosticadas com estrabismo. O estrabismo ? uma defici?ncia ocular associada ? capacidade de movimenta??o dos olhos, caracterizada por qualquer desvio no alinhamento ocular perfeito. Al?m do aspecto est?tico, a crian?a pode relatar vista emba?ada ou dupla . Problemas oftalmol?gicos n?o diagnosticados corretamente s?o motivos de muitos abandonos da escola. O Minist?rio da Educa??o do Brasil aponta as defici?ncias visuais como um grande desafio aos educadores de crian?as, principalmente no processo de alfabetiza??o. O exame oftalmol?gico tradicional para diagn?stico do estrabismo pode ser realizado induzindo os movimentos oculares atrav?s de instru??es do m?dico ao paciente. Esse procedimento pode ser reproduzido com aux?lio computacional atrav?s da an?lise de imagens capturadas em v?deo. Este trabalho apresenta uma proposta de sistema de teleoftalmologia para auxiliar profissionais da sa?de no diagn?stico a dist?ncia de defici?ncias visuais associadas ? capacidade motora dos olhos, como o estrabismo. Espera-se atrav?s deste trabalho contribuir diretamente para a melhoria dos ?ndices do aprendizado escolar infantil, permitindo melhores condi??es de diagn?stico e, consequentemente, acompanhamento do aluno
