A 21-year-old myope presented with decreased vision and corneal edema following vitreoretinal surgery for retinal detachment. While intraocular pressure (IOP) measurement with Goldmann applanation tonometer (GAT) was low, the digital tonometry indicated raised pressures. An interface fluid syndrome (IFS) was suspected and confirmed by clinical exam and optical coherence tomography. A tonopen used to measure IOP through the peripheral cornea revealed elevated IOP which was the cause of the interface fluid. Treatment with IOP-lowering agents resulted in complete resolution of the interface fluid. This case is being reported to highlight the fact that IFS should be suspected when there is LASIK flap edema and IOP readings using GAT are low and that GAT is not an optimal method to measure IOP in this condition. Alternative methods like tonopen or Schiotz tonometry can be used.
一名 21 岁的近视患者在接受视网膜脱离的玻璃体视网膜手术后出现视力下降和角膜水肿。虽然 Goldmann 压平眼压计（GAT）测量的眼压较低，但数字眼压计显示眼压升高。怀疑存在界面液综合征（IFS），并通过临床检查和光学相干断层扫描得到证实。使用眼压计通过周边角膜测量眼压，结果显示眼压升高，这是界面液的原因。通过降低眼压的药物治疗，界面液完全消退。本病例报告旨在强调当 LASIK 瓣水肿且 GAT 眼压读数较低时，应怀疑存在 IFS，并且 GAT 不是这种情况下测量眼压的最佳方法。可以使用眼压计或 Schiotz 眼压计等替代方法。
