Validity of digital measurement of visual acuity and contrast sensitivity in Parkinson’s disease
VA and CS can be measured with SSS in PD with moderate comparability to reference eye charts (dependent on cpd for CS), and digital outcomes may provide clinically meaningful outcomes to use in PD trials. A range of human, technological and protocol factors may impact validity of VA and CS measurement via SSS, which should be further examined in future studies.
