Summary:It was investigated whether essential tremor (ET) patients would exhibit visual impairments. Studies published in the following databases were reviewed: PubMed, BIREME, CINAHL, Web of Science, PsycINFO, SciELO, SCOPUS, and ELSEVIER, from inception to January 05th, 2017. Two independent reviewers performed screening, data extraction, and assessment of the data. The NIH assessment tools used to assess study quality. Out of 132 references, 12 were selected according to the eligibility criteria. Results indicated that ET patients have lower visual sensitivity when compared to control groups. There was no significant evidence for color vision impairment. Despite the findings for heterogeneity, visual impairments in ET patients were observed, and these may be one of the main non-motor clinical characteristics. KEYWORDS: tremor, essential tremor, visual perception, vision Investigou-se a relacao entre percepcao visual e tremor essencial (TE). Realizou-se uma revisao dos estudos publicados sobre o tema nas bases de dados PubMed, BIREME, CINAHL, Web of Science, PsycINFO, SciELO, SCOPUS e ELSEVIER desde a origem ate 05 de janeiro de 2017. A triagem, extracao de dados e avaliacao foram realizadas por dois revisores. Para avaliar a qualidade dos estudos utilizou-se as diretrizes do National Institutes of Health (NIH). De 132 estudos potencialmente elegiveis, 12 foram selecionados de acordo com os criterios de elegibilidade. Os resultados indicaram que pessoas com TE apresentam baixa sensibilidade visual quando comparados com individuos saudaveis, apesar de nao apresentarem prejuizos na visao de cores. Apesar da heterogeneidade dos dados, observamos que existem prejuizos visuais em pessoas com TE e estes podem ser uma das principais caracteristicas clinicas nao-motoras.
