摘要
目的 应用增强深部成像的光学相干断层扫描(EDI-OCT)技术定量分析硅油取出术后黄斑中心凹下脉络膜厚度(SFCT)的变化.方法 27例硅油眼(观察组,A组)行硅油取出术,比较术前1天、术后1天、2周、1个月及3个月时术眼与对侧眼27眼(对照组,B组)的平均SFCT值.结果 A组在硅油取出术前后的所有时间点SFCT均明显大于B组(P<0.05);A组术后各时间点SFCT与术前比较差异有统计学意义(P<0.01),且术后1个月时SFCT显著高于其他时间点(P<0.01);B组SFCT变化无明显差异(P>0.05).结论 硅油取出术前后,术眼SFCT较非手术眼均明显增大,术后3个月内术眼黄斑中心凹下脉络膜呈增厚趋势,且术后1个月增厚最明显,术后3个月时呈下降趋势,但仍未降至术前水平.
Objective To observe the change of subfoveal choroidal thickness(SFCT)with enhanced depth imaging optical coherence tomography(EDI-OCT)after silicone oil removal.Methods 27 silicone oil-filled eyes(observation group,the group A)were treated with silicone oil removal,27 unaffected side eyes(compared group)were set as the group B.All of their average SFCT were compared preoperatively,1 day,2 weeks,1 month and 3 months after surgery.Results SFCT at each point of the group A was significantly higher than that of the group B(P<0.05).Sharp increase of SFCT after surgery in the group A had significant difference than the preoperative data and reached its peak at 1 month(P<0.01).Then the SFCT was decreasing at the 3rd month after operation(P<0.01).However,there was no statistical significance in data of the group B(P>0.05).Conclusion SFCT at each point of affected eyes is significantly higher than that of unaffected eyes before and after silicone oil removal.SFCT of operative eyes is increasing within 3 months especially in 1 month after surgery.However,there is decreasing trend of the data in affected eyes at the 3rd month after surgery,but it still not return to the level of preoperative SFCT.
