黄斑出血的病因诊断

Etiological diagnosis for macular hemorrhage

目的 :对不明原因的黄斑出血作进一步病因诊断。方法 :对 2 7例 (2 8只眼 )患者常规检查未发现明显原因的黄斑出血的眼底 ,眼底荧光血管造影和必要的吲哚青绿血管造影检查进行分析 ,判断引起黄斑出血的原因。结果 :16例 (17只眼 )为高度近视引起 ,平均年龄为 4 7 4岁 ,其中 2例发生脉络膜新生血管膜 ;9例 (9只眼 )为老年性黄斑变性 ,平均年龄为 6 2 7岁 ,其中脉络膜新生血管膜 7例 ,2只眼为黄斑地图样变性 ;1例 (1只眼 )黄斑部血管异常而引起出血 ;1例 (1只眼 )为脉络膜肿物。结论 :老年患者的不明原因的黄斑出血的发病原因以老年性黄斑变性较多见 ,而年轻患者以高度近视为主。

Objective:To make the correct etiological diagnosis of the macular hemorrhage.Methods:27 patients (28 eyes),aged 19～79 years (mean,50.7 years),with sudden onset of impairment of vision,were examined,including fluorescence angio graphy and indocyanine green angiography if necessary.Results:16 patients (17 eyes),mean age 47.4 years,were diagnosed as high myopia.Of whom,2 had choroidal neovascularization(CNV).9 patients(9 eyes),mean age 62.7 years,were induced by age-related macular degeneration,CNV was found in 7 of them,the other 2 had geographic atrophy;1patient was diagnosed as macular vessel abnormality,while 1 patient had choroidal tumor.Conclusion:Among the patients with macular hemorrhage of unknown cause,in the older patients,age-related macular degeneration was the main cause,whereas high myopia was the main cause for the younger patients.
