Self-Reported Visual Complaints in People with Parkinson’s Disease: A Systematic Review

“…a Difference in score or prevalence between the groups, b Weighted prevalence of complaints on the ICF functions ‘seeing functions’ (72.9%) and ‘difficulty with watching’ (78.2%), c Items that may to some extent have arisen from motor symptoms (e.g., bumping into objects and freezing in narrow spaces) were included in the analysis. Prevalence was 57% after removing these items, d Khedr et al (2012) [ 90 ] & Khedr et al (2013) [ 55 ], and Giorelli et al (2014) [ 65 ] & Giorelli et al (2014) [ 66 ] used the same group of people with PD and reported the same results. For this reason, results of only one of these studies was reported, e Results only account for the non-tremor group ( N = 12), f Results only account for the tremor group ( N = 13), g Weighted prevalence of complaints on size (17%) and shape perception (21%), h Weighted prevalence of reading related complaints: ‘letters disappear while reading’ (20% in patients and 5% in controls) and ‘read better with one eye closed’ (17% in patients and 6% in controls), i Weighted prevalence of the complaints freezing (60% in patients and 3% in controls) and difficulty at doorways (56% in patients and 3% in controls) [ 119 ].…”
