摘要
目的:运用光学相干断层扫描术(OCT)回顾性分析高度近视白内障超声乳化摘除联合人工晶状体植入术后BCVA<0.3组和BCVA≥0.3组黄斑中心凹视网膜厚度,分析其与术后视力的相关性。方法:本研究为回顾性临床研究,共纳入行白内障超声乳化摘除联合人工晶状体植入的高度近视白内障患者70例70眼,于术后1wk;1,3mo进行随访,记录最佳校正视力(BCVA),并根据术后1wk BCVA分为BCVA<0.3组和BCVA≥0.3组,两组患者于术后1,3mo行OCT检查,测量黄斑中心凹视网膜厚度。采用相关分析研究术后BCVA恢复情况及其与黄斑中心凹视网膜厚度的相关性。结果:患者术前,术后1wk;1,3mo的BCVA<0.05的眼的比分别为30%,14%,11%,7%。BCVA<0.3组术后1,3mo的黄斑中心凹视网膜厚度均较BCVA≥0.3组明显增加,两组术后3mo黄斑中心凹视网膜厚度均较术后1mo明显降低(P<0.01)。术后3mo BCVA和OCT检查黄斑中心凹视网膜厚度之间存在统计学上显著相关(r=-0.716,P<0.05)。结论:在本研究中,术后所有患者在3mo的随访时间内视力得到一定程度的提高,且术后OCT检查黄斑中心凹视网膜厚度与术后视力的恢复情况相关。
AIM ： To retrospectively evaluate central foveal thickness in highly myopic eyes with best correct visual acuity（ BCVA） or ≥ 0. 3 after phacoem ulsification（ Phaco） using optical coherence tomography（ OCT） and to investigate correlation between post- operative BCVA and central foveal thickness. METHODS： In this retrospective clinical study, we consecutively recruited 70 low highly myopic cataract subjects（ 70 eyes） underwent Phaco. Postoperative visits w ere performed at 1w k,1 and 3 o. Postoperative BCVA ere recorded and further divided into 2 groups with BCVA and ≥ than 0. 3. Central foveal thickness was easured by OCT 1 and 3mo after surgery. Chi-square test was used to compare preoperative and postoperative BCVA. Pearsion＇s correlation was used to evaluate relationship between postoperative BCVA and central foveal thickness.RESULTS： The ratio of BCVA0. 05 was 30%,14%,11%and 7% respectively for per-operation,1w k,1 and 3m o post- operation. After surgery, the central foveal thickness was significantly increased in group with BCVA0. 3 com paring to group w ith BCVA ≥0. 3. Three m onth post-operation,central foveal thickness was significantly decreased in both groups com paring to that in 1m o post-operation（ P 0. 01）. There has significant correlation betw een 3m o postoperative BCVA and central foveal thickness（ r =-0. 716,P〈0. 05）.CONCLUSION： In this study,BCVA is improved after3 mo follow up. There has significant correlation betw een postoperative BCVA and central foveal thickness.
