一般认为植物神经功能紊乱是引起美尼尔氏病的病因,但还缺少有力的证据。有作者报道美尼尔氏病发作时患侧瞳孔扩大,认为这是交感神经活动亢进或副交感神经麻痹所引起,并认为是美尼尔氏病患侧植物神经功能紊乱的证据。为对此问题进一步探讨,作者们通过自制的双眼红外线瞳孔测量仪,利用结膜囊内滴入乙酰甲胆硷试验,观测了16例正常人、71例美尼尔氏病患者、5例迷路炎和4例前庭神经炎患者的瞳孔变化。试验在暗室进行。被检查者先仰卧休息10分钟,然后拍摄试验前的瞳孔图象5张;再于照明下,
Generally believed that autonomic dysfunction is the cause of Meniere’s disease, but there is still no strong evidence. Some authors report the expansion of the ipsilateral pupil at the time of onset of Meniere’s disease, which is believed to be caused by hyperactivity of sympathetic or parasympathetic nerve paralysis and is believed to be evidence of autonomic dysfunction in the affected side of Meniere’s disease. To further explore this issue, the authors through the homemade binocular infrared pupil measuring instrument, the use of conjunctival hydrocolloid methacholine dropping test observed 16 normal subjects, 71 cases of Meniere’s disease, 5 cases of labyrinthitis And 4 cases of vestibular neuritis in patients with pupil changes. Test in a dark room. The examinee first supine rest for 10 minutes, and then shot before the test pupil image 5; then in the lighting,
