To evaluate possible advantages of spectral domain optical coherence tomography (SD-OCT) in epiretinal membranes.
Patients with idiopathic epiretinal membranes (ERMs) were examined before and after vitreoretinal surgery. Cirrus SD high-definition (HD)-OCT was compared with Stratus time domain OCT to find correlations with visual acuity (VA) and metamorphopsia.
Five consecutive patients were enrolled. With Cirrus HD-OCT, it was possible to differentiate between the ERM and the retinal surface in all patients. In areas where the ERM was adherent, this differentiation was severely limited with Stratus OCT. We found no significant correlations between Cirrus OCT and Stratus OCT for retinal thickness and VA. However, we found a relationship between metamorphopsia and topographic maps of the internal limiting membrane.
Cirrus HD-OCT improved the preoperative evaluation of ERMs, offered a topographic reconstruction of the vitreomacular interface, and improved identification of retinal structures.
评估频域光学相干断层扫描(SD - OCT)在视网膜前膜中的潜在优势。
对特发性视网膜前膜(ERM)患者在玻璃体视网膜手术前后进行检查。将Cirrus SD高清(HD) - OCT与Stratus时域OCT进行比较,以寻找与视力(VA)和视物变形的相关性。
连续纳入5例患者。使用Cirrus HD - OCT,在所有患者中均能区分ERM与视网膜表面。在ERM粘连的区域,Stratus OCT严重限制了这种区分。我们发现Cirrus OCT与Stratus OCT在视网膜厚度和VA方面无显著相关性。然而,我们发现视物变形与内界膜地形图之间存在关联。
Cirrus HD - OCT改善了ERM的术前评估,提供了玻璃体黄斑界面的地形图重建,并改善了视网膜结构的识别。
