蓝黄和自动视野检查法在原发性开角型青光眼诊断中的对比研究

目的 对比蓝黄视野检查法(Blueon Yellow Perimetry,BYP)和自动视野检查法(Standard Automatic Perimerty,SAP)在原发性开角型青光眼(Primary Open Angle Glaucoma,POAG)诊断中的应用.方法 选择POAG患者72例120只眼,男性46例76只眼,女性26例44只眼,左50只眼,右70只眼,年龄16～79岁,平均(43.87±17.53)岁,应用HUMPHERY750Ⅱ-i电脑自动视野计的标准检测程序和蓝黄视野榆测程序分别进行SAP和BYP的检测.结果 POAG早期SAP和BYP检测中,BYP更能在视野缺损深度和缺损范围上反映青光眼的视功能损害程度.POAG进展期BYP检测出部分SAP所不能检测出的缺损部位,检测到的缺损深度和SAP相同.POAG晚期的SAP和BYP检测到相同的缺损范围和缺损深度.视野指数中异常阈值点数最能反映POAG早期视野损害.结论 BYP比SAP更加适用于POAG的早期视野损害的筛查,在视功能出现广泛的受损时,BYP反映视野缺损的能力与SAP相当.

Comparison between Blue on Yellow Perimetry and Standard Automatic Perimerty in diagnosis of Primary Open Angle Glaucoma

Objective To evaluate application of Blue on Yellow Perimetry(BYP)and Standard Au-tomatic Perimerty(SAP)in the diagnosis of primary open angle glaucoma(POAG)patients.Methods A total of 72 patients (120 eyes)diagnosed POAG were enrolled for SAP and BYP examination.There were 26 females (44 eyes)and 46 males (76 eyes).50 left eyes, 70 Right eyes.Mean (SD)age of the patients was 43.87(17.53) years(range, 16-79 years).All patients were both examined blue on yellow with FASTPAC and SAP with SITA Standard strategy separately,using the Humphrey Field Analyzer 750 Ⅱ-i and Program 30-2.Results In the early period POAG patients,BYP compared SAP with the scope of defect was usually increased,deeper and wider.In the moderate POAG patients,BYP could detect some defects that SAP could not,and showed the same defect depth as SAP.In the advanced period the ability of BYP to reflect the visual field damage is as same as SAP.In visual field index for the diagnosis of contributions,the defect points are with the best diagnos-tic value.Conclusions BYP should be more suitable for the screening of POAG suspected.When extensive vi-sual field damage occurred, the diagnostic capability of BYP was equal to SAP.
