重视瞳孔检查在神经眼科疾病诊断中的作用

瞳孔对光反射能够反映视路传入通路和瞳孔传出神经(交感和副交感神经)的功能状况,而临床七瞳孔在生理和病理状态下的变化常被忽视,正确掌握常规简捷的瞳孔检查方法,可以帮助我们捕捉到异常的瞳孔光反应,有助于疾病的临床早期诊断.在瞳孔检查时,特别需注意排除影响检查结果的各种因素,恰当地运用瞳孔药敏试验有助于正确地选择神经电生理和神经影像学检查,为神经眼科疾患的确诊提供有效的临床证据.

Pay attention to application of pupil reaction testing in assessment of neuro-ophthalmologic disorders

The pupillary light reaction represents the functions of either the afferent visual pathway or the pupillary efferent innervations (parasympathetic and sympathetic).Physiologic and pathologic changes of pupil were usually ignored by the physicians.A correct pupil renction testing will be of benefit to catch the abnormal pupil reaction as well as the early diagnosis of neuro-ophthalmologic disorders.A precise pupil reaction test is hardly performed because of the variation of individual,illumination and the instantaneous change of pupil.The proper pharmacologic testing is helpful for ehoosing the right neuro-electrophysiological and neuro-image examinations,and also may be of instuction value on the diagnosis of neuro-ophthalmologic diseases.
