目的:探讨玻璃体切割术治疗玻璃体积血的临床效果。方法:采用玻璃体切割术治疗玻璃体积血患者21例21眼。观察玻璃体切割术后视力改善情况及分析导致玻璃体积血的原因。结果:本组21例患者中末次随访最佳矫正视力:数指/眼前～者4例,0.05～者12例,≥0.3者5例,脱盲率(视力≥0.05)81%,脱残率(视力≥0.3)24%;导致玻璃体出血的前三位病因分别是分支静脉阻塞、无脱离视网膜裂孔和糖尿病视网膜病变,三者共占76%。结论:玻璃体切割术治疗玻璃体积血安全有效,大部分患者术后视力可得到明显提高。

AIM:To analyze the clinical efffect of vitrectomy for vitreous hemorrhages.METHODS:Twenty-one cases(21 eyes)with vitreous hemorrhages underwent vitrectomy,their visual acuity was observed and the factors causing vitreous hemorrhages were analyzed.RESULTS:Of all the 21 cases,best-corrected visual acuity at last follow-up was:counting fingers-0.05 in 4 cases,≥0.05-0.3 in 12 cases,≥0.3 in 5 cases,off-blindness rate(visual acuity≥0.05)was 81%,off-disability rate(visual acuity≥0.3)was 24%.The first three leading causes of vitreous hemorrhage were branch vein occlusion,retinal breaks without detachment and diabetic retinopathy,accounting for 76% in all.CONCLUSION:Vitrectomy for vitreous hemorrhage is a safe and effective method,most patients can significantly improve their visual acuity after operation.
