目的 探讨视网膜大动脉瘤的临床特征。 方法 对 15例视网膜大动脉瘤患者行荧光素眼底血管造影和眼科常规检查。 结果 视网膜大动脉瘤位于视网膜动脉第 1分支者 6例 ,第 2分支者 7例 ,第 3分支者 2例。瘤体位于颞上支动脉 4例 ,颞下支动脉 10例 ,颞侧上下支动脉均有者 1例。呈单个血管瘤者 13例 ,动脉瘤直径在 2 5 0～ 5 0 0μ m。 结论 荧光素眼底血管造影检查可有助于视网膜大动脉瘤的诊断 ,如果出血累及黄斑区时 ,可行光凝治疗
Objective To investigate the clinical features of retinal aneurysms. Methods Fifteen patients with retinal aneurysm underwent fundus fluorescein angiography and ophthalmology routine examination. Results The retinal artery aneurysm was located in the first branch of retinal artery in 6 cases, the second branch in 7 cases, the third branch in 2 cases. The tumor was located in 4 cases of superior temporal artery, 10 cases of inferior temporal artery, and 1 case of superior and inferior temporal artery. 13 cases were single hemangioma, aneurysm diameter in 250 ~ 5 0 0 m. Conclusion Fluorescein angiography can be helpful in the diagnosis of retinal aneurysm. If bleeding affects the macula, feasible photocoagulation
