方法：回顾性分析2011-03/2015-03因玻璃体积血在我院行玻璃体切割的原发性高血压患者83例83眼，根据术中所见，其中有28眼玻璃体积血由视网膜中央静脉阻塞引起，术后随访9～36(平均22.4)mo。检查记录患者手术前后最佳矫正视力、术后并发症情况，并进行统计分析。

结果：视网膜中央静脉阻塞玻璃体积血合并原发性高血压发生率为33.7%； 术后最佳矫正视力3.3～4.5，术后最佳矫正视力提高24眼(86%)，视力不变4眼(14%)，无视力下降患者，手术前后视力相比差异有统计学意义(P<0.05)； 术后发生黄斑水肿5眼，发生率18%； 所有患者术后均没有发生视网膜脱离及复发玻璃体积血。

结论：手术治疗合并原发性高血压的视网膜中央静脉阻塞玻璃体积血疗效好，可减少并发症，提高视力。

METHODS: Totally 83 eyes of 83 consecutive primary hypertension patients with vitreous hemorrhage underwent vitrectomy were included. In 28 eyes of 28 patients, vitreous hemorrhage was caused by central retinal vein occlusion. All patients were followed up for 9-36mo, meanly 22.4mo. Main outcome measures included the best corrected visual acuity, intraoperative and postoperative complications,and the data were statistically analyzed and compared.

RESULTS: The incidence of vitreous hemorrhage in primary hypertension complicated with central retinal vein occlusion was 33.7%. The best corrected visual acuity increased in 24 eyes(86%), unchanged in 4 eyes(14%), there was a significant statistical difference between pre-operation and post-operation(P<0.05). There were 5 eyes(18%)with macular edema after the surgery.There were no serious complications in and after the surgery in all 28 eyes.

CONCLUSION: Vitrectomy is a safe and effective treatment for vitreous hemorrhage in primary hypertension complicated with central retinal vein occlusion.
