【摘要】：目的评估特发性黄斑前膜经23G微创玻璃体切割术后视功能及黄斑区结构的变化。方法回顾性分析了28例(28眼)于我院行23G微创玻璃体切割术+内界膜剥除术+玻璃体注射2mg曲安奈德的黄斑前膜患者临床资料,术前术后行最佳矫正视力、眼压、眼底照相、眼底OCT检查,术后随访半年。结果 25例25眼患者视力提高,3例3眼视力未见提高;最佳矫正视力由术前的0.17±0.10提高至术后的0.37±0.22(P0.05)。黄斑中心凹厚度也由术前的(498.07±116.95)μm降至术后的(329.46±111.15)μm,差异有统计学意义(t=7.730,P0.05)。线性相关分析发现术后最佳矫正视力的好坏与术后黄斑中心凹厚度呈明显的线性相关(r=0.413,P=0.029)。大部分患者在随访期内黄斑中心凹黄斑厚度未能降至正常。结论黄斑前膜剥除术可以很好地改善患者的视功能,明显改善黄斑中心凹结构,但是大部分患者黄斑中心凹厚度未能完全恢复正常。
[Abstract]:Objective to evaluate the changes of visual function and macular area structure after 23 G minimally invasive vitrectomy of idiopathic anterior macular membrane. Methods the clinical data of 28 patients (28 eyes) with macular membrane treated by 23 G minimally invasive vitrectomy with 2mg triamcinolone acetonide were retrospectively analyzed. The best corrected visual acuity, intraocular pressure and fundus photography were performed before and after operation. The fundus OCT was followed up for half a year after operation. Results the visual acuity of 25 cases (25 eyes) was improved, 3 cases (3 eyes) had no improvement, and the best corrected visual acuity (BCVA) increased from 0.17 卤0.10 before operation to 0.37 卤0.22 after operation (P0.05). The thickness of macular fovea also decreased from (498.07 卤116.95) 渭 m before operation to (329.46 卤111.15) 渭 m after operation, and the difference was statistically significant (P 0.05). Linear correlation analysis showed that there was a significant linear correlation between the postoperative best corrected visual acuity and the thickness of macular fovea (r = 0.413 P0. 029). The macular foveal macular thickness did not decrease to normal in most patients during the follow-up period. Conclusion anterior macular membrane excision can improve the visual function and the structure of fovea of macular, but the thickness of fovea in most patients can not return to normal completely.
