Further observation was made of 100 cases of occlusion amblyopia (form vision deprivation amblyopia) in order to study the symptomatology and the results of treatment by intensive occlusion of the sound eye. The occlusion was classified into three categories: (1) Short-term total occlusion after entropion or other minor lid surgery, (2) Long-term total occlusion lasting more than 2 weeks as a consequence of unilateral congenital or traumatic cataract, (3) Long-term incomplete occlusion as in the case of a small punctate posterior pole cataract or a linear scar of the corneal endothelium. Ocular deviations, fixation pattern, and retinal correspondence were examined. The visual evoked response (VER) was studied with reference to the recovery of visual acuity after treatment. Th occurrence of amblyopia and the recovery of visual acuity were analysed in relation to the age at the time of occlusion and the age at the time of treatment in order to clarify the critical or sensitive period in the development of visual system in humans.
为了研究症状学以及健眼密集遮盖法的治疗效果，对100例遮盖性弱视（形觉剥夺性弱视）患者进行了进一步观察。遮盖分为三类：（1）睑内翻或其他轻微眼睑手术后的短期完全遮盖；（2）单侧先天性或外伤性白内障导致的持续超过2周的长期完全遮盖；（3）小的点状后极白内障或角膜内皮线性瘢痕情况下的长期不完全遮盖。检查了眼位偏斜、注视模式和视网膜对应情况。参照治疗后视力的恢复情况研究了视觉诱发电位（VER）。分析弱视的发生和视力的恢复与遮盖时的年龄以及治疗时的年龄的关系，以阐明人类视觉系统发育中的关键期或敏感期。
