非超声乳化小切口白内障术后糖尿病视网膜病变的激光治疗

Laser photocoagulation for diabetic retinopathy after small incision nonphacoemulsification extraction

目的:探讨非超声乳化小切口白内障摘除人工晶状体植入术后糖尿病视网膜病变激光治疗的时机及效果。方法:对41例68眼行非超声乳化小切口白内障摘除人工晶状体植入术后的糖尿病视网膜病变患者在眼底荧光血管造影(FFA)指导下早期予以激光光凝。结果:光凝治疗后41例68眼术后随访均满1a,其中视力提高19眼(28%);视力不变40眼(59%);视力下降9眼(13%),总有效率为87%。由于先处理已存在的黄斑水肿,未见全视网膜光凝术后黄斑水肿加重。结论:适时的白内障非超声乳化摘除人工晶状体植入术后合理及时的进行激光光凝,能有效的控制糖尿病视网膜病变的进展,稳定视力。FFA是进行正确有效激光重要参考依据。

·AIM：To evaluate the results of laser photocoagulation for diabetic retinopathy after small incision nonphacoemulsification extraction combined with intraocular lens implantation and to determine the time for the laser photocoagulation.·METHODS：According to the results of fundus fluorescein angiography（FFA）,totally 68 eyes of 41 cases were treated with the laser photocoagulation earlier after nonphacoemulsification extraction combined with intraocular lens implantation.·RESULTS：After one year＇s follow-up,visual acuity was improved in 19 eyes（28%）,remained stable in 40 eyes（59%）and decreased in 9 eyes（13%）.The total effective rate was 87%.Because the macular edema was treated first,no one was found bad after photocoagulation.·CONCLUSION：Reasonable laser photocoagulation is preferable for diabetic retinopathy patients after nonphacoemulsification extraction.It can control or delay the advance of diabetic retinopathy,and steady the visual acuities in future.FFA is a very important reference for photocoagulation.·
