The medical records of 90 patients with a clinical diagnosis of retinal vein occlusion (RVO) who were seen at two referral hospitals in Saudi Arabia were reviewed. Sixty-eight (75.6%) were men. Central RVO was present in 50 patients (55.6%); branch RVO, in 35 patients (38.9%); and hemiretinal occlusion, in five patients (5.6%). Arterial hypertension was present in 43 patients (47.8%); diabetes mellitus, in 28 patients (31%); and preexisting glaucoma, in 26 patients (28.9%). The date of onset of RVO was available in 61 patients. Eighteen attacks (29.5%) had occurred during the month of Ramadan. The Student's t test of paired samples indicated that the incidence of RVO during the month of Ramadan was significantly higher than that of the other months of the Gregorian year. These findings suggest that dehydration may play a role in the pathogenesis of RVO.
对沙特阿拉伯两家转诊医院临床诊断为视网膜静脉阻塞（RVO）的90例患者的病历进行了回顾。其中68例（75.6%）为男性。50例患者（55.6%）为中央视网膜静脉阻塞；35例患者（38.9%）为分支视网膜静脉阻塞；5例患者（5.6%）为半侧视网膜阻塞。43例患者（47.8%）有动脉高血压；28例患者（31%）有糖尿病；26例患者（28.9%）有既往青光眼病史。61例患者有视网膜静脉阻塞的发病日期。18次发作（29.5%）发生在斋月期间。配对样本的t检验表明，斋月期间视网膜静脉阻塞的发生率明显高于公历年份的其他月份。这些发现提示脱水可能在视网膜静脉阻塞的发病机制中起作用。
