Abstract

PURPOSE

To study the subconjunctival silicone oil (SCSO) parameters associated with dellen formation following microincision vitrectomy (MIV).

PATIENTS AND METHODS

This was a case-control study of 20 eyes with SCSO following MIV. Ten of them suffered postoperative dellen formation. Dellen occurrence, their sizes, number of loci, and distance between SCSO and the limbus were recorded. The outcome after silicone-oil removal was evaluated.

RESULTS

The SCSO was at 3.1±1.2 mm from the limbus. All cases with dellen had SCSO within 2 mm of the limbus (<0.001). No other factors were found to be associated with dellen formation (age, =0.414; sex, =0.656; laterality, =1; indication for pars plana vitrectomy, =0.655; instrument gauge, =0.211; circumference involved by SCSO, =0.252). All the dellen healed after surgical evacuation of SCSO (<0.001), leaving scars.

CONCLUSION

Dellen can be associated with MIV secondary to SCSO near the limbus. Resolution with scarring occurred following SCSO evacuation. Therefore, SCSO should be evacuated as early as possible to avoid long-term peripheral corneal morbidity.

摘要

目的

研究与微切口玻璃体切除术（MIV）后睑裂斑形成相关的结膜下硅油（SCSO）参数。

患者与方法

这是一项对20只MIV术后使用SCSO的眼睛进行的病例对照研究。其中10只出现了术后睑裂斑形成。记录睑裂斑的发生情况、大小、位点数量以及SCSO与角膜缘之间的距离。评估硅油取出后的结果。

结果

SCSO距角膜缘3.1±1.2mm。所有出现睑裂斑的病例，其SCSO均在角膜缘2mm范围内（<0.001）。未发现其他因素与睑裂斑形成相关（年龄，P = 0.414；性别，P = 0.656；左右侧，P = 1；玻璃体切割术的适应证，P = 0.655；器械规格，P = 0.211；SCSO累及的范围，P = 0.252）。所有睑裂斑在手术清除SCSO后均愈合（<0.001），并留下瘢痕。
