Purpose: Observing the features of electro-activities at macular region in age-related macular degeneration (AMD), and evaluating the sensitivities of local electroretinogram (LERG).

• 目的:观察老年黄斑变性(AMD)对视网膜黄斑部电活动影响特征,并对局部视网膜电图(LERG)的敏感性作出评价。 方法:对80例AMD患者99只眼进行了黄斑区三个范围局部视网膜电图(LERG)测定,并与患者的视力及相应检测范围病损面积进行了对比研究。
