Conclusion This study provides a descriptive catalogue of vision-specific PRO instruments , to inform the choice of an appropriate measure of patient-reported outcomes in a glaucoma context
Purpose To identify  vision Patient-Reported Outcomes instruments relevant to glaucoma and assess their content validity .
The relationship between visual disability and visual field in patients with glaucoma.
PURPOSE To evaluate the relationship between visual disability and the remaining visual field in glaucoma patients . DESIGN Prospect i ve noncomparative survey . PARTICIPANTS One hundred forty-seven Japanese patients with glaucoma were examined . METHODS Using a previously developed question naire , we assessed the relationship between visual disability indices and both the visual field examined using program 30 - 2 of the Humphrey Field Analyzer and visual acuity . MAIN OUTCOME MEASURES Pearson 's correlation coefficients between visual disability indices and the 22 visual field and 2 visual acuity measurements were calculated . Multiple regression analysis with stepwise variable selection identified factors significantly contributing to visual disability . RESULTS We identified a significant correlation between visual disability and both the visual field and visual acuity measurements collected . Of the factors examined , retinal sensitivity in the lower hemifield within 5 degrees of the fixation and visual acuity in the better eye significantly contributed to all the item and total disability indices ( DIs ) , measurements of the degree of visual disability as evaluated by the question naire ; visual acuity in the worse eye contributed to two of the seven item DIs , as well as the total DI . The R value for total DI ( R = 0.87 , P < 0.0001 ) indicated that approximately 76 % of the visual disability could be explained by these factors . CONCLUSIONS The Japanese glaucoma patients ' visual disability is explained primarily by retinal sensitivity in the lower hemifield within 5 degrees of the fixation and visual acuity in the better eye and secondarily by visual acuity in the worse eye
