Blue-on-yellow perimetry and macular threshold perimetry in the diagnosis of early primary glaucoma / 中华眼底病杂志

ABSTRACT

ObjectiveTo evaluate the diagnosis of blue-on-yellow perimetry and macular threshold perimetry in early primary glaucoma. MethodsHumphrey Ⅱ-750 automatic perimetry was used to test 60 eyes of 60 cases in normal control group and 63 eyes of 63 cases in early primary glaucoma group with white-on-white perimetry (W/W), blue-on-yellow perimetry (B/Y), and macular threshold perimetry (MTP). The results of the visual field defects detected by the three perimetries were compared and analyzed.ResultsThe differences of mean sensibility of W/W, B/Y and MTP between the two groups had statistical significance [t=-3.01, P=0.005 4 (W/W); t=-2.95, P=0.006 3 (B/Y); t=-2.59,P=0.015 0 (MTP)]. In the diagnosis of early primary glaucoma, the sensitivity of MTP was the highest (83%), B/Y was the second (65%), and W/W was the lowest (48%). When B/Y and MTP were combined, the sensitivity was improved to 94% using parallel testing, and the specificity was improved to 87% using serial testing. ConclusionsB/Y and MTP are valuable in diagnosis of early primary glaucoma, and the sensitivity and specificity of the diagnosis can be improved when B/Y and MTP are combined.
