摘要
目的观察糖尿病视网膜病变（DR）患者在晶状体超声乳化术后黄斑中心区视网膜及中心凹下脉络膜厚度的改变。方法非增生性糖尿病视网膜病变患者行晶状体超声乳化术39例（39眼）为DR组，再根据是否合并临床有意义的黄斑水肿（ME），分为ME＋组和ME-组。选择同期无DR者的超声乳化术为对照组。以OCT观察术前和术后1个月黄斑中心区（半径500μm内）的视网膜厚度和中心凹下脉络膜厚度的变化。结果DR组中ME-组24眼，ME＋组15眼，对照组30例（30眼），超声乳化术中及术后均无严重并发症。术后3个组黄斑中心区视网膜厚度均较术前增厚（P=0．002，0．007，0．001），而术后中心凹下脉络膜厚度则均无明显改变（P=0．058，0．264，0．514）。结论超声乳化术后DR患者和非DR者黄斑中心区视网膜均较术前增厚，同时中心凹下脉络膜厚度均无明显改变。
Objective To observe the changes of central macular retinal thickness （CMRT） and subfoveal choroidal thickness （SFCT） after phacoemulsification in eyes with non proliferative diabetic retinopathy （DR）. Methods Thirty-nine eyes of 39 patients of cataract with DR and 30 eyes of 30 patients of cataract without diabetes were enrolled. The DR patients were divided into ME ＋ group and ME-group according to evidence of clinically significant macular edema. All cases were examined by optical coherence tomography before cataract surgery and repeated 1 month after surgery. The changes of CMRT （r 〈 500 I^m） and SFCT were observed. Results DR groups included 24 eyes of ME - group and 15 eyes of ME ＋ group. No complication occurred during or after operation. After surgery the CMRT in three groups were more than those before surgery （P =0. 002, 0. 007, 0. 001 ） , but no significant change was verified for SFCT in all groups （ P = 0. 058, 0. 264, 0. 514 ）. Conclusion The CMRT of DR or non DR patients is more after phacoemusification than before surgery. There is no change in SFCT after surgery.
