摘　　要：目的 :评价蓝 /黄视野计 (blue on yellowperimetry ,B/Y)又叫短波视野计short wavelengthperimetry与标准白色视野计 (white on whiteperimetry ,W /W )检测早期青光眼的敏感性。方法 :采用瑞士产Octopus 10 1型全自动视野计对早期原发性开角型青光眼 17例 3 4只眼 ,对照组正常人 8例 16只眼 ,进行B/Y及W /W检测 ,视野检测采用tG2 测试程序 ,将中心 3 0°视野内全视网膜光敏感度均值及各象限光敏感度均值 (dB)进行比较分析。结果 :两种视野计检测正常人B/Y较W /W检测全视网膜光敏感度均值低 ,两者相差 3 96dB ,差异有显著意义 (t =5 11,P <0 0 0 1) ,对应各象限视网膜光敏感度均值比较 ,差异均有显著意义 (P <0 0 0 1) ,早期开角型青光眼B/Y较W /W检测全视网膜光敏感度均值差为 5 3 4dB ,差异有显著意义 (t =5 87,P <0 0 0 1) ,对应各象限视网膜光敏感度均值差 5dB以上 ,差异有显著性 (P <0 0 0 1) ,视网膜光敏感度均值依次为鼻下 >颞下 >鼻上 >颞上 ,以B/Y检测出的缺损面积大且深 ,按矫正偏差图 (cor rectedprobability)计算P <2以上缺损点数 ,显示B/Y检测结果大于W /W检测结果 ,前者为后者的 2 2 3倍 ,差异有显著意义( χ2 =13 0 4,P <0 0 0 5 ) ,早期开角型青光眼组 3 4只眼B/Y检测视野?Objective:To assess the value of blue-on-yellow perimetry in the diagnosis of early primary open angle glaucoma (POAG). Methods:34 eyes of 17 patients with early POAG and a group of 8 normal persons (16 eyes) were examined both by the blue-on-yellow (B/Y) perimetry and standard white-on-white (W/W) perimetry.The mean light sensitivities (MS) of the central 30° and in each quadrant were analyzed. Results:In controls,the difference of MS either in central 30° or in each corresponding quadrant between perimetries was significant (P<0 001).MS was higher than that in B/Y.In POAG,MS of full-field retina or the corresponding quadrant in W/W was higher than that in B/Y (P<0 001).MS in four quadrants were different,it was lowered in the order:inferior nasal quadrant,inferior temporal,superior nasal and superior temporal.The defects in B/Y perimetry were larger and deeper than that in W/W perimetry.With the parameter of corrected deviation point,the positive patients who had defected points were significantly higher in B/Y perimetry (70 59%,24/34) than that in W/W perimetry (41 18%,14/34) (χ 2=13 04,P<0 005). Conclusions:A good coincidence is demonstrated between B/Y and W/W perimetries both in normal and in early POAG groups.B/Y perimetry is more sensitive in detecting early defects than W/W perimetry.The positive rate of visual field defect is higher and the defects are larger and deeper in B/Y perimetry than that in W/W perimetry.It is suggested that B/Y perimetry can be applied in diagnosing early glaucoma.
