为评价全视野暗视敏感度（ｗｈｏｌｅ－ｆｉｅｌｄｓｃｏｔｏｐｉｃｓｅｎｓｉｔｉｖｉｔｙ，ＷＳＳ）测定对原发性开角型青光眼（ｐｒｉｍａｒｙｏｐｅｎ－ａｎｇｌｅｇｌａｕｃｏｍａ，ＰＯＡＧ）的早期诊断价值，经过３０分钟暗适应后，对１６例（１７只眼）早期ＰＯＡＧ，１２例（１４只眼）进展期ＰＯＡＧ，２５例（３２只眼）可疑ＰＯＡＧ及１５例（２０只眼）年龄匹配的正常人进行ＷＳＳ阈值测定。结果：这四组的平均ＷＳＳ阈值差异均具有显著性，分别为６．２４±２．４６ｄＢ，７．７９±２．１９ｄＢ，３．６３±２．４６ｄＢ，１．８５±１．６９ｄＢ。在可疑ＰＯＡＧ组中，随着危险因素的增加，ＷＳＳ阈值有上升趋势。ＷＳＳ阈值与ＰＯＡＧ患者的眼压最高水平值呈正相关（ｒ＝０．７６６，Ｐ＜０．００１）。结论：ＷＳＳ测定在青光眼的筛选中具有潜在性价值。
To assess the value of whole-field prediction sensitivity (WSS) in the early diagnosis of primary open angle glaucoma (POAG), after 30 minutes dark adaptation, 16 patients (17 eyes ) WSS thresholds were determined for early POAG, 12 (14 eyes) advanced POAG, 25 (32 eyes) suspicious POAG and 15 (20 eyes) age-matched normal subjects. Results: The mean WSS threshold differences among the four groups were significant, which were 6.24 ± 2.46dB, 7.79 ± 2.19dB, 3.63 ± 2.46dB and 1.85 ± 1.69dB, respectively. In the suspected POAG group, the WSS threshold increased with the increase of risk factors. The WSS threshold was positively correlated with the highest intraocular pressure in patients with POAG (r = 0.766, P <0.001). Conclusion: The WSS assay has potential value in the screening of glaucoma.
