蓝/黄自动化视野检测原发性开角型青光眼

目的 :探讨蓝 /黄 (B/ Y)自动化视野在早期开角型青光眼 (POAG)患者视敏度检测中的敏感性和应用价值。方法 :以 Humphry- 75 0视野机对 31例 (4 5眼 )早期 POAG患者作常规白色 (W/ W)视野和蓝 /黄视野 (B/ Y)检测。结果 :B/ Y视野出现的光敏度异常下降点数较 W/ W视野多 (B/ Y视野为 11.5 778± 5 .4 334,W/ W视野为10 .86 6 7± 5 .332 6 ,t=2 .973,P<0 .0 1)。B/ Y视野的 GHT指标的异常程度比 W/ W视野明显 (χ2 =7.111,P<0 .0 1) ,其中两种视野 GHT均为临界或异常者 30例 ,均正常者 6例 ,B/ Y视野 GHT临界或异常而 W/ W视野正常者 9例 ,W/ W视野 GHT临界或异常的病例 B/ Y视野 GHT均有异常。W/ W和 B/ Y视野的 MD指标两组间差异无显著性 (χ2 =3.2 73,P>0 .0 5 )。结论 :B/ Y视野检查在检测早期 POAG中较 W/ W视野灵敏度高。

Blue-on-yellow perimetry in patients with primary open-angle glaucoma

OBJECTIVE: To investigate the early changes of the blue-on-yellow (B/Y) perimetry in patients with early primary open-angle glaucoma(POAG). METHODS: Thirty-one cases (45 eyes) of POAG underwent the central 30 degrees field examination of B/Y as well as routine white-on-white (W/W). RESULT: No significant difference of mean index deficiency (MD) between B/Y and W/W perimetry was detected (P>0.05). However, there were marked changes in index GHT (glaucoma hemisphere test) and more defect points in B/Y visual field than those in W/W (P<0.01). CONCLUSION: B/Y perimetry might be more sensitive than W/W perimetry a potentially more and valuable method in detection of early POAG lesion.
