The oral administration of 400 mg/day for one month of zinc sulphate, when compared with placebo, provoked normal plasma zinc level in treated patients, principally men in their forties, with bilateral, retrobulbar, axial, optic neuropathy related to excessive smoking and consumption of ordinary wine and/or beer and/or spirits. Treatment significantly improved visual capacity (measured with Friedmann analyser) of the central scotoma area (5 degrees).
与安慰剂相比，每天口服400毫克硫酸锌，持续一个月，可使接受治疗的患者（主要是四十多岁的男性）的血浆锌水平恢复正常，这些患者患有与过度吸烟以及饮用普通葡萄酒和/或啤酒和/或烈酒相关的双侧、球后、轴性视神经病变。治疗显著改善了中心暗点区域（5度）的视力（用弗里德曼分析仪测量）。
