¹ = 0.042 for preperimetric glaucoma versus dry AMD and  = 0.002 for healthy subjects versus dry AMD. For question 2, the scores awarded for the possible options are as follows: 1, very dissatisfied, 2, rather dissatisfied, 3, fairly satisfied, and 4, very satisfied. For the rest of the questions, the scores for possible answers are as follows: 1, very great difficulty, 2, great difficulty, 3, some difficulties, and 4, no difficulties. Thus, a higher score represents better patient-perceived outcomes.
