摘要:目的 分析視網膜中央動脈阻塞(central retinal artery occlusion,CRAO)患者的凝血功能情況,推測血栓形成是否是CRAO發病的主要危險因素。方法 回顧性研究將CRAO患者作為病變組,與之年齡、性別相匹配的普通人群作為對照組,進行凝血功能檢查,將統計結果進行t檢驗,評價凝血功能差異是否有統計學意義及臨床意義。結果 60例病變組與60例對照組凝血功能進行比較:49例男性病變組與49例男性對照組凝血功能進行比較,PT活動度、國際標準化比值、纖維蛋白原三項檢查,差異具有統計學意義(P<0.05),卻無臨床意義。11例女性病變組和11例女性對照組凝血功能檢查,PT活動度和纖維蛋白原兩項,差異具有統計學意義(P<0.05),卻無臨床意義。結論 CRAO患者與普通人群相比,凝血功能檢查結果差異無臨床意義。CRAO患者無明顯血栓形成傾向,進一步推測血栓形成不是CRAO的主要病因。

Abstract:Objective To analyze the central retinal artery occlusion(central retinal artery occlusion,CRAO)the blood coagulation function of patients, whether that thrombosis is a major risk factor for the onset of CRAO.Methods A retrospective study of CRAO patients as the disease group,with age and sex matched normal people as control group,coagulation function examination,statistics the results of t test,the difference of coagulation function and clinical significance of evaluation of whether there is statistical significance.Results 60 cases of disease group and 60 cases of control group were compared with blood coagulation function:49 cases of male disease group and 49 cases of male control group blood coagulation function were compared,PT activity,international normalized ratio,fibrinogen three check,the difference was statistically significant(P<0.05),but no clinical significance.11 cases of female disease group and 11 cases of female control group coagulation tests,PT activity and fibrinogen of two,the difference was statistically significant(P<0.05),but no clinical significance.Conclusion The CRAO patients compared with the general population,coagulation function test results showed no clinical significance.CRAO patients had no tendency to thrombosis,further speculation that thrombosis is not the main cause of CRAO.

視網膜中央動脈阻塞(central retinal artery occlusion,CRAO)是眼科致盲性急癥之一,預后差。病因仍不是十分明確,尚無公認有效的治療方法。普遍認為該病的發生與栓子栓塞、血栓形成、血管炎癥、動脈痙攣、外傷等因素有關,栓子栓塞和血栓形成是最為重要的兩個因素。病因是治療的前提,哪個因素更為重要,備受關注。栓子栓塞在國際上已被多次討論,血栓形成報告較少,臨床用于篩查是否有血栓形成、凝血機制是否正常的三項指標為:凝血酶原時間(prothrombin time,PT)、活化部分凝血活酶時間(activated partial thromboplatin time,APTT)和纖維蛋白原(Fibrinogen,FIB)。由于該病發病率較低,文獻國內尚無視網膜中央動脈阻塞患者凝血分析的報告。本研究對60例患者和60例對照組進行凝血分析,為治療提供依據。
