目的分析白细胞计数和眼部以外的炎症与视网膜动脉阻塞之间的关系。方法对９４例视网膜中央或分支分动脉阻塞患者进行回顾性分析。将患者分为伴有炎症组和不伴有炎症组，并设立年龄和性别配对的对照组。结果５４例（５８％）伴有炎症性疾病，其中只有１４例（２６％）炎症直接侵犯眼部。白细胞计数在２组视网膜动脉阻塞组中均显著高于对照组（Ｐ＜０．０５）。结论眼部以外组织的炎症可能是视网膜动脉阻塞的诱发因素之一。白细胞计数在视网膜动脉阻塞患者中的升高可能是对视网膜缺血性损害的炎症性反应
Objective To analyze the relationship between white blood cell count and inflammation outside the eye and retinal artery occlusion. Methods A retrospective analysis was performed on 94 patients with central retinal detachment or sub-arterial occlusion. The patients were divided into the group with inflammation and without inflammation, and the control group with age and gender matched. Results Fifty-four (58%) patients had an inflammatory disease, of which only 14 (26%) had direct inflammation of the eye. Leukocyte count was significantly higher in the two groups of retinal artery occlusion group than in the control group (P <0.05). Conclusion Inflammation outside the ocular tissues may be one of the inducing factors of retinal artery occlusion. Elevated white blood cell counts in patients with retinal artery occlusion may be an inflammatory response to retinal ischemic damage
