最近,美国的研究人员报道,对黄斑变性病人投用一种含氧化剂和锌的补充药物,可推迟与年龄相关的黄斑变性的发展,并且能降低视力丧失的危险性。美国贝塞斯达美国国立眼科研究所的Emily chew对这种方法持积极态度。chew认为,尽管此种疗法不是一种可治愈黄斑变性的方法,不能适用于每个人,但该疗法肯定为许多以前根本没有接受任何治疗的病人提供了希望。关键是需要病人接受一次扩瞳检查,以便了解他们视网膜的真实情况,以及确定是否需要这种混合药物治疗。
Recently, US researchers reported that the administration of a supplemental drug containing oxidants and zinc to patients with macular degeneration may delay the development of age-related macular degeneration and reduce the risk of vision loss. Emily Chew of the National Eye Institute at Bethesda in the U.S. holds a positive attitude toward this approach. Although this treatment is not a cure for macular degeneration and can not be applied to everyone, chew believes that the treatment certainly offers hope to many patients who previously had no treatment. The key is to have the patient undergo a dilated pupil examination in order to understand the true condition of their retina and to determine if this combination therapy is needed.
