Diplopia Is Frequent and Associated with Motor and Non-Motor Severity in Parkinson's Disease: Results from the COPPADIS Cohort at 2-Year Follow-Up. Diagnostics (Basel). 2021 Dec 17;11(12):2380.2075-4418https://hdl.handle.net/10668/27953Diplopia is relatively common in Parkinson's disease (PD) but is still understudied. Our aim was to analyze the frequency of diplopia in PD patients from a multicenter Spanish cohort, to compare the frequency with a control group, and to identify factors associated with it. PD patients who were recruited from January 2016 to November 2017 (baseline visit; V0) and evaluated again at a 2-year ± 30 days follow-up (V2) from 35 centers of Spain from the COPPADIS cohort were included in this longitudinal prospective study. The patients and controls were classified as "with diplopia" or "without diplopia" according to item 15 of the Non-Motor Symptoms Scale (NMSS) at V0, V1 (1-year ± 15 days), and V2 for the patients and at V0 and V2 for the controls. The frequency of diplopia in the PD patients was 13.6% (94/691) at V0 (1.9% in controls [4/206]; p Diplopia represents a frequent symptom in PD patients and is associated with motor and non-motor severity.enAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/PIGDParkinson’s diseaseTremorchangesmotorphenotypeHumansProspective StudiesParkinson DiseaseFollow-Up StudiesDiplopiaSpainControl Groupsresearch article34943619open accessDiplopíaPacientesEspañaGrupos controlEstudios prospectivosEnfermedad de ParkinsonOrganización Mundial de la Salud10.3390/diagnostics11122380PMC8700703https://www.mdpi.com/2075-4418/11/12/2380/pdf?version=1639744054https://pmc.ncbi.nlm.nih.gov/articles/PMC8700703/pdf
