Choroidal neovascularization ( cnv ) secondary to age - related macular degeneration ( amd ) also involves the abnormal rapid growth of vascular tissues . the photosensitizing drug administered will bind specifically to the abnormal vessel 由于老年黄斑退化会引致脉络膜新增不正常的血管，而光动力疗法所用的感光药物正好协助把不正常的血管堵塞。
In - situ diagnostics will permit us to arrest some diseases before clinical symptoms even appear . much earlier diagnoses will be possible for diabetes , alzheimer s , age - related macular degeneration , glaucoma and cataracts 原位诊断可以使我们甚至在临床症状出现之前就抑制某些疾病的发生，让更早期地诊断出糖尿病、阿尔滋海默症、老年性黄斑变性、青光眼、白内障成为可能。
Although other factors , such as diet may contribute to these findings , physical activity is known to reduce systemic inflammation and endothelial dysfunction , both hypothesized to have a role in the pathogenesis of age - related macular degeneration 尽管节食等因素对这些结果可能有影响，但有人根据体育活动已知可以减轻全身炎症和内皮功能障碍，推测其对于年龄相关黄斑变性的发病也有作用。
Cardiovascular disease and age - related macular degeneration may share common risk factors , such as weight , blood pressure , systemic inflammation , and endothelial dysfunction , they noted , and physical activity is known to improve the heart - risk profile 研究人员指出，心血管疾病和年龄相关性黄斑变性可能有共同的危险因子，比如体重、血压、全身炎症以及血管内皮功能障碍等，而体育活动能在总体上改善心脏病的危险因素。
Cigarette smoking is an important risk factor for cardiovascular , respiratory , and malignant diseases . there is also a strong association between smoking and a number of common eye diseases , which include dysthyroid eye disease , age - related macular degeneration , glaucoma , and cataract 吸烟不但会引致心血管病呼吸系统病和癌症，而且跟多种眼疾都有关系，这包括因甲状腺功能过盛所引致的眼疾老年黄斑退化白内障青光眼等。

As patients may be asymptomatic at the early stage of disease , and early treatment can minimize further vision loss , so it is important for elders to have reg ular eye examination age - related macular degeneration can result in permanent vision loss ; thus elders should seek medical attention promptly if they notice problems in central vision or color vision 定期的眼睛检查:定期的眼睛检查是发现老年性黄斑点退化的唯一方法，因患者可能没有自觉症状，而及早治疗可防止视力进一步减低，所以定期的眼睛检查对长者尤为重要老年性黄斑点退化是可引致视力永久丧失的眼疾，所以长者如果出现中心视力色觉或其他视力问题，应尽快求医，早作检查。
Dark green leafy vegetables such as broccoli , spinach , collards , turnip greens and yellow vegetables and fruits such as apricots are rich in biochemical substances that protect vision from one of the major factors in age - related macular degeneration , say richard bone , professor of physics , and john landrum , associate professor of chemistry , in the latest issue of the journal methods in enzymology 物理教授理察柏恩及化学副教授约翰兰卓姆最近在酵素学方法期刊上发表指出，深绿色叶子的蔬菜，像花椰菜菠菜芥蓝大头菜，还有黄色的蔬菜和水果，像是杏桃，都含有一些丰富的生化物质，这些生化物质是对抗中老年视斑性退化的一个主要因素。
