Abstract(s)
Este trabalho é o culminar de seis meses de trabalho e relata três casos clínicos compreendidos na vasta área da optometria que foram trabalhados durante o estágio.
O primeiro diz respeito a uma patologia, nomeadamente o glaucoma. Esta é uma doença que é considerada uma das principais causas de cegueira no mundo. Afeta as células do nervo óptico, impedindo que a imagem formada pela retina possa chegar ao cérebro. Caracteriza-se por alterações na papila do disco óptico e dos campos visuais, estando geralmente acompanhadas por pressão intraocular elevada. É geralmente assintomático e, por essa razão, detectado tardiamente. A avaliação da visão binocular é uma importante área da Optometria. Caso não esteja totalmente funcional pode provocar sintomas que afetam o normal funcionamento da visão e bem estar. A insuficiência de convergência é um problema de visão binocular que se caracteriza pela incapacidade de obter e/ou manter uma adequada convergência sem esforço, ou seja, pela dificuldade em manter o alinhamento binocular a uma distância próxima. A contactologia é um dos ramos da Optometria. O terceiro caso refere-se a uma adaptação de lentes de contacto hidrófilas, como uma solução alternativa e bem conseguida, à utilização de compensação em lentes oftálmicas em pacientes com astigmatismo. Seguidamente, apresentar-se-á um estudo sobre cada uma destas temáticas.
This work is the culmination of six months of work and reports three clinical cases comprised in the vast area of optometry that were worked during the internship. The first concerns a pathology, namely glaucoma. This is a disease that is considered one of the leading causes of blindness in the world. It affects the cells of the optic nerve, preventing the image formed by the retina from reaching the brain. It is characterized by alterations in the optic disc and visual fields, being generally accompanied by elevated intraocular pressure. It is usually asymptomatic and, for this reason, lately detected. The evaluation of binocular vision is an important area of optometry. If not fully functional, it may cause symptoms that affect normal vision and well-being. The convergence insufficiency is a binocular vision problem that is characterized by the inability to obtain and/or maintain an adequate and effortless convergence, that is, by the difficulty in maintaining the binocular alignment at a close distance. Contact lenses adaptation is one of the branches of Optometry. The third case concerns an adaptation of hydrophilic contact lenses, as an alternative and well-achieved solution, to the use of compensation in ophthalmic lenses in patients with astigmatism. Then, a study will be presented on each of these themes.
