计算机视野检查在前部缺血性视神经病变疗效评价中的作用

目的探讨计算机视野检查在前部缺血性视神经病变疗效评价中的作用。方法对前部缺血性视神经病变患者60例（84眼）治疗前后均采用对数视力表和计算机视野计分别做视力及视野检测，并进行分析。结果经药物治疗1个月后，治愈24眼（28．6％）、显效16眼（19．0％）、有效8眼（9．5％）、无效36眼（43．0％）；治疗无效的36眼中有24眼视力无提高但视野缺损范围缩小40％以上，患者自觉症状好转，原视野缺损处光敏度回升，平均光敏度（MS）明显提高，平均缺损（MD）、丢失方差（LV）明显下降，治疗前后差异有统计学意义（P〈0．05）。结论计算机视野是评价前部缺血性视神经病变疗效的一个重要指标，视野的改变比视力的变化更能明确治疗效果。

Analysis value of computerized visual-field examination during treatment of anterior ischemic optic neuropathy

Objective To explore the analysis value of computerized visual-field examination during treatment of anterior ischemic optic neuropathy （AION）. Methods 60 patients （84 eyes） with AION were observed. Visual acuity and visual field were measured with logarithmic visual acuity chart and perimeter before and after therapy. Results After 1 month of medication, 24 cases（28.6% ） were cured , and the therapy was obviously effective in 16 （ 19.0% ） , effective in 8（9.5% ）, and ineffective in 36（43.0%）. The visual acuity of 24 among these ineffective 36 cases was not increased, but the percentage of the visual field defect decreased by more than 40%. The symptoms of the patients were relieved. The visual sensitivity was elevated in the defect area of the visual field. The mean sensitivity was obviously improved, and the mean defect and loss variance were decreased significantly. Conclusions Computerized visual-field examination plays an important role in evaluating treatment effect of AION. The change of perimetry is more explicit than that of visual acuity in treatment evaluation.
