Abstract

Aim. To find out the influence of learning effect on various reliability parameters and global indices of standard automated perimetry in cases of primary open angle glaucoma. Method. Thirty eyes of 30 patients of Primary Open Angle Glaucoma constituted material for this prospective observational study. All the patients underwent standard automated perimetry three times on three different days within one week on G program of Octopus Visual Field Analyzer. The details of reliability indices, global indices, and test duration were compiled and analyzed. Result. A male preponderance was observed with a mean age of 53.43 years. The mean false positive was found to be 11.13, 6.07, and 2.40 on visit 1, visit 2, and visit 3, respectively. The mean false negative was found to be 13.73, 9.33, and 6.30 on visit 1, visit 2, and visit 3, respectively. The mean fixation loss was found to be 7.53, 3.83, and 1.60 on visit 1, visit 2, and visit 3, respectively. The mean deviation was found to be -10.14, -5.75, and -3.11 on visit 1, visit 2, and visit 3, respectively. The pattern standard deviation was found to be 5.58, 4.63, and 4.35 on visit 1, visit 2, and visit 3, respectively. The mean test duration was found to be 7.68, 6.21, & 5.51 minutes for visit 1, visit 2 and visit 3, respectively. All the values were statistically highly significant except for the pattern standard deviation. Conclusion. At least three standard automated perimetry tests should be performed for all glaucoma patients in order to obtain a base line perimetry chart.

学习效果对原发性开角型青光眼患者标准自动视野的可靠性参数和总体指标的影响。
目标了解学习效应对原发性开角型青光眼患者标准自动视野的各种可靠性参数和总体指标的影响。方法30例原发性开角型青光眼患者的30只眼睛构成了这项前瞻性观察性研究的材料。所有患者在一周内的三天内使用Octopus视野分析仪的G程序进行三次标准自动视野测量。对可靠性指标、全局指标和测试持续时间的详细信息进行了汇编和分析。后果男性占优势,平均年龄53.43岁。访视1、访视2和访视3的平均假阳性分别为11.13、6.07和2.40。访视1、访视2和访视3的平均假阴性分别为13.73、9.33和6.30。访视1、访视2和访视3的平均固定损失分别为7.53、3.83和1.60。访视1、访视2和访视3的平均偏差分别为-10.14、-5.75和-3.11。访视1、访视2和访视3的模式标准差分别为5.58、4.63和4.35。访视1、访视2和访视3的平均测试持续时间分别为7.68、6.21和5.51分钟。除模式标准差外,所有值均具有统计学高度显著性。结论所有青光眼患者应至少进行三次标准的自动视野检查,以获得基线视野图。
