We studied 187 patients attending special educational institutions in Saudi Arabia who were blind before the age of 14. All patients underwent complete ophthalmological evaluation. The visual acuity in 31% of the patients was no light perception and in 58% light perception to counting fingers at 3 feet (1 m). 70% were blind before age 2. Prior to 1962 acquired diseases led to blindness in 75% of the patients. From 1962 onwards genetically determined diseases accounted for 84% of childhood blindness. 56% of this group were the product of consanguineous marriages. On the other hand in the group who acquired blindness only 14% were from consanguineous marriages (p less than 0.0001). We here describe guidelines for the prevention of childhood blindness in Saudi Arabia.
我们研究了沙特阿拉伯特殊教育机构中187名14岁之前失明的患者。所有患者均接受了全面的眼科评估。31%的患者视力为无光感，58%的患者视力为光感至3英尺（1米）处能数指。70%的患者在2岁前失明。1962年以前，75%的患者因后天疾病导致失明。从1962年起，基因决定的疾病占儿童失明的84%。该组中56%为近亲结婚的产物。另一方面，在后天失明组中，只有14%来自近亲结婚（p<0.0001）。我们在此描述沙特阿拉伯预防儿童失明的指导方针。
