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.
