Materials and Methods
Subjects were taken from an ongoing longitudinal study of glaucomatous progression at Discoveries in Sight Laboratories, Devers Eye Institute, Portland, Oregon. Subjects with early glaucoma and suspected glaucoma were recruited and have been followed annually for up to 10 years. Detailed inclusion and exclusion criteria, including clinical characteristics, are tangential to this study but have been described elsewhere.12, 13, 14 The study adheres to the tenets of the Declaration of Helsinki and
Results
Figure 2 shows histograms of the raw scores for each test. Table 1 summarizes the raw scores for each of the 7 tests and the by-subject ranks for the 7 tests. IOP was the highest-rated test, followed by HRT and FDT. SWAP received the lowest average score, with 48 subjects ranking SWAP as their least favorite or joint least favorite test. Table 2 shows the 7 tests in order of mean rank, along with P values from pairwise comparisons of ranks.
Discussion
The patient's opinion of a particular test is not the only factor when choosing which tests to perform. The expected clinical utility of the results will generally be the primary consideration. However, the patient's experience is an important factor to consider. For some patients, it is possible that it may affect their willingness to return for follow-up visits and the frequency of visits they will tolerate. In a disease such as glaucoma, which generally progresses slowly, this may be

Previous research has explored participants, experiences of visual field assessment8,26,27; however, the novel focus of our study was to enquire directly about willingness to vary test duration, number of tests per visit, and visit frequency and to ask people to priority rank areas for future perimetric development and potential translation into practice. Regarding visual field test frequency, a variety of recommendations appear in the literature designed to improve early detection of visual field progression within the first 2 years of initial diagnosis and for monitoring thereafter.11,12,38,39
