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。
Objective To explore the role of computer vision in evaluating the curative effect of anterior ischemic optic neuropathy. Methods Sixty eyes (84 eyes) of patients with anterior ischemic optic neuropathy were examined with visual acuity and visual field before and after treatment. Results One month after the drug treatment, 24 eyes (28.6%) were cured, 16 eyes (19.0%) were effective, 8 eyes (9.5%) effective and 36 eyes (43.0%) ineffective; No improvement but the scope of visual field defect reduced by more than 40%, the patient’s symptoms improved, the sensitivity of the original visual field defect rose, the average photosensitivity (MS) was significantly increased, the average defect (MD), loss of variance (LV) decreased significantly before and after treatment There was statistical significance (P <0.05). Conclusion Computer vision is an important index to evaluate the curative effect of anterior ischemic optic neuropathy. The change of visual field is more clear than the change of visual acuity.
