Methods: Twenty-seven eyes of 27 patients with essential tremor were included in this study. Twenty-seven eyes of 27 healthy volunteers served as controls. All eyes were examined with spectral domain optical coherence tomography (OCT) (Retinascan Advanced RS-3000; NIDEK, Gamagori, Japan) using image filling software program (NAVIS-EX, NIDEK, Tokyo, Japan). Results: No statistically significant difference was detected between ET patients and control group for overall (RNFL) and foveal retinal thickness parameters. [RNFL thickness (Average thickness p=0.86, superior average p=0.22, inferior average p=0.24, nasal average p=0.06, temporal average p=0.88), foveal retinal thickness p=0.63] There was no relationship between OCT parameters and age, gender and duration of ET (all p>0.05). Conclusion: We did not find altered RNFL and foveal thickness values in patients with ET compared to controls. Retinal thickness changes do not seem to be a potentially useful biomarker in ET patients.eninfo:eu-repo/semantics/closedAccessArticle2043633662-s2.0-84953257312Q4WOS:000367386600006Q4
