The study of early closure of macular hole after surgery is difficult with intraocular gas. Using silicone oil tamponade, which gives easy access to the fundus from the first postoperative day, the optical coherence tomography (OCT) has been used to make a fine analysis of the macula.
Our study included 13 eyes with macular hole which have undergone a vitrectomy with silicone oil tamponade. An OCT was performed before the surgery, on the first postoperative day (J1), 1 week (S1) and 1 month (M1) after surgery.
The hole closure was confirmed with OCT on the first postoperative day in 11/13 cases. One week after surgery, 12 holes were closed. An old larger hole did not close but its borders were flattened and loosed the cystic aspect.
OCT in macular hole surgery with silicone oil tamponade confirms that in the majority of the cases the hole closes within the first 24 hours. It seems that the hole closure could be speeded by internal limiting membrane peeling.
眼内注入气体时，研究黄斑裂孔术后的早期闭合情况存在困难。使用硅油填充，术后第一天即可方便地观察眼底，光学相干断层扫描（OCT）已被用于对黄斑进行精细分析。
我们的研究纳入了13只接受了硅油填充玻璃体切除术的黄斑裂孔眼。术前、术后第一天（J1）、术后1周（S1）和术后1个月（M1）均进行了OCT检查。
13例中有11例在术后第一天经OCT证实裂孔闭合。术后1周，12个裂孔闭合。一个较大的陈旧性裂孔未闭合，但其边缘变平，囊样外观消失。
硅油填充的黄斑裂孔手术中，OCT证实大多数情况下裂孔在术后24小时内闭合。似乎内界膜剥除可加速裂孔闭合。
