Amblyopia results from degradation of the retinal image during a sensitive period of visual development. Amblyopia is the most common cause of visual loss in children. Because of the failure in detection and in treatment, amblyopia is still an important cause of visual loss in adults. Results from recent randomised trials in amblyopia should change our approach to screening and treatment. Based on the current evidence, if a single screening session is used, screening at school entry could be the most efficient screening moment. Between researchers, however, there still exists a lot of controversy on the benefit of visual screening.
弱视是由于视觉发育敏感期视网膜图像退化所致。弱视是儿童视力丧失的最常见原因。由于检测和治疗方面的不足，弱视仍是成人视力丧失的一个重要原因。近期弱视随机试验的结果应会改变我们的筛查和治疗方法。根据目前的证据，如果只进行一次筛查，入学时筛查可能是最有效的筛查时机。然而，研究人员之间对于视力筛查的益处仍存在诸多争议。
