非外伤非增生性糖尿病视网膜病变玻璃体积血原因分析

目的：探讨非外伤非增生性糖尿病视网膜病变玻璃体积血的原因。

方法：对2009-07/2013-06在我科住院的46例46眼玻璃体积血病例资料进行回顾性病因分析。

结果：本组中视网膜静脉阻塞(RVO)所致玻璃体积血最多，为16眼(34.8%)，其次为视网膜裂孔及孔源性视网膜脱离(RH/RD)8眼(17.4%)，渗出型年龄相关性黄斑变性(EAMD)8眼(17.4%)，再次为玻璃体后脱离(PVD)4眼(8.7%)，其它少见原因为视网膜大动脉瘤3眼(6.5%)、高血压视网膜病变及视网膜静脉周围炎各2眼(4.3%)，特发性息肉样脉络膜血管病变、脉络膜上腔出血、葡萄膜炎各1眼(2.2%)。

结论：视网膜静脉阻塞、视网膜裂孔及孔源性视网膜脱离、年龄相关性黄斑变性是非外伤非增生性糖尿病视网膜病变玻璃体积血的主要原因。

Etiological factors in non-traumatic non-proliferative diabetic retinopathy vitreous hemorrhage

AIM: To analyze the etiological factors in non-traumatic nonproliferative diabetic retinopathy vitreous hemorrhage.

METHODS: The etiological factor in a total of 46 patients(46 eyes)with follow-up records from July 2009 to June 2013 in our department were analyzed retrospectively.

RESULTS:Retinal vein occlusion(RVO)was the principal cause(16 eyes, 34.8%), the second were retinal hole or retinal detachment(RH/RD)and exudative age-related macular degeneration(EAMD)(8 eyes, 17.4%), the third was posterior vitreous detachment(PVD)(4 eyes, 8.7%). The other rare causes were retinal macroaneurysm(3 eyes, 6.5%), hypertension(2 eyes, 4.3%), Eales' disease(2 eyes, 4.3%), polypoidal choroidal vaseulopathy(PCV)(1 eye, 2.2%), suprachoroidal hemorrhage(SCH)(1 eye, 2.2%), uveitis(1 eye, 2.2%).

CONCLUSION: Retinal vein occlusion, retinal hole or retinal detachment, and exudative age-related macular degeneration are frequent causes of non-traumatic non-proliferative diabetic retinopathy vitreous hemorrhage.
