METHODS: A total of 63 eyes of 63 patients with idiopathic Parkinson''s disease were evaluated using a three-dimensional protocol of swept-source optical coherence tomography. The following layers were analyzed: full retinal thickness, retinal nerve fiber layer, ganglion cell layer, and choroid. The coefficient of variation was calculated for every measurement. RESULTS: In the macular area, the mean coefficients of variation of retinal thickness, ganglion cell layer + thickness, and choroidal thickness were 0.40%, 0.84%, and 2.09%, respectively. Regarding the peripapillary area, the mean coefficient of variation of the retinal nerve fiber layer thickness was 2.78. The inferior quadrant showed the highest reproducibility (coefficient of variation= 1.62%), whereas the superonasal sector showed the lowest reproducibility (coefficient of variation= 8.76%). CONCLUSIONS: Swept-source optical coherence tomography provides highly reproducible measurements of retinal and choroidal thickness in both the macular and peripapillary areas. The reproducibility is higher in measurements of retinal thickness versus choroidal thickness. info:eu-repo/semantics/openAccess by https://creativecommons.org/licenses/by/4.0/deed.es 0.872 2020 OPHTHALMOLOGY 60 / 62 = 0.968 2020 Q4 T3 0.602 2020 Ophthalmology 2020 Q2 Medicine (miscellaneous) 2020 Q2 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Garcia-Martin, Elena Universidad de Zaragoza (orcid)0000-0001-6258-2489 Orduna, Elvira Universidad de Zaragoza (orcid)0000-0003-2710-1875 Vilades, Elisa Alarcia, Raquel Rodrigo, María J.
