Forty patients with a history of alcohol abuse were treated with a 2% solution of methacholine to determine the prevalence of iridic parasympathetic denervation. Three (8%) of the alcoholics showed iris constriction of 1.0 mm or more, compared with three (8%) control subjects. In contrast, damage to the iridic parasympathetic nerve supply occurs in approximately 80% of patients with diabetes mellitus as determined by the same pharmacological technique.
对40名有酗酒史的患者使用2%的乙酰甲胆碱溶液进行治疗，以确定虹膜副交感神经去神经支配的患病率。与3名（8%）对照受试者相比，3名（8%）酗酒者出现了1.0毫米或更大程度的虹膜收缩。相比之下，采用相同药理学技术测定，约80%的糖尿病患者存在虹膜副交感神经供应受损。
