A random sample of 9548 Palestinian Arabs living in the West Bank and Gaza Strip was identified, and 9054 (95.7%) were examined. Particular attention was directed to reduced visual acuity (VA) and its cause and to trachoma. Low visual acuity was defined as less than 6/18 in both eyes and binocular blindness as a VA less than 3/60 in both eyes. The overall incidence of low VA was 6.8% and of binocular blindness 1.7%. The three principal causes of blindness in order of frequency were cataract, trachoma, and corneal leucoma. These three conditions accounted for 66.7% of binocular blindness. Trachoma was present in 2568 (28.4%) of the 9054 people examined.
在约旦河西岸和加沙地带生活的9548名巴勒斯坦阿拉伯人被随机抽取为样本，其中9054人（95.7%）接受了检查。特别关注了视力下降（VA）及其原因以及沙眼。低视力被定义为双眼视力低于6/18，双眼盲被定义为双眼视力低于3/60。低视力的总体发病率为6.8%，双眼盲的发病率为1.7%。按频率排序，导致失明的三个主要原因是白内障、沙眼和角膜白斑。这三种情况占双眼盲的66.7%。在接受检查的9054人中，有2568人（28.4%）患有沙眼。
