视网膜静脉阻塞继发黄斑部浆液性视网膜脱离临床观察

Clinical observation on serosity macular detachment secondary to retinal vein occlusion

目的观察视网膜静脉阻塞(retinal vein occlusion,RVO)继发黄斑部浆液性视网膜脱离的发病情况和临床特点。方法收集2005年5月至2006年4月在我院就诊的96例(97眼)视网膜中央静脉阻塞和视网膜分支静脉阻塞患者,对其眼底荧光血管造影和光学相干断层扫描检查的结果进行分析。结果97眼中有48眼继发黄斑部浆液性视网膜脱离,黄斑部脱离高度为66～937μm,平均(293.21±56.26)μm,脱离范围大多局限于中心凹。4眼严重者脱离可达近下方血管弓处,脱离边缘可见视网膜下积血。在RVO继发黄斑囊样水肿患者中,同时继发黄斑部浆液性视网膜脱离的占53.03%.结论RVO继发黄斑部浆液性视网膜脱离的发病率远高于以往报道,是引起RVO患者视力下降的主要原因之一,治疗中应给予充分的重视。

Objective To observe the incidence and clinical features of serosity macular detachment secondary to retina vein occlusion （RVO）. Methods Ninety-six consecutive patients （ 97 eyes ） with central retinal vein occlusion or branch retinal vein occlusion from May,2005 to April,2006 in our hospital were collected. All the eases accepted fimdus fluorescein angiography and optical coherence tomography examination,and the results were analyzed by software. Results Serosity macular detachment ocurred in 48 eyes of 97 eyes （ 49.48% ）, in which the range of the retina thickness was 66 ～ 937μm with an average of （ 293.21 ± 56.26 ）μm. In most eases, the detachment area was confined to the central fovea of macula, and which in 4 serious cases with subretinal hemorrhage reached the inferior vascular arcus at the margins, Among the cystoid macular edema associated with RVO eases,53.03% was involved in serosity macular detachment, Conclusion The incidence of serosity macular detachment secondary to RVO is higher than that in previously reported, which appears to be one of the major factors leading to vision descending. More attention should be given to the patients involved in this condition.
