BACKGROUND
Biomicroscopy, B-scan ultrasound imaging, and SD-OCT are all modalities used to characterize a posterior vitreous detachment (PVD). Our objective is to assess the precision of the diagnosis of PVD by SS-OCT.
METHODS
This prospective observational study examines ninety-five eyes of forty-nine patients with biomicroscopy, B-scan ultrasound, and SS-OCT for the presence or absence of a complete PVD. All SS-OCT images were reviewed by two retina specialists (RWSC, ZM). All three diagnostic methods were evaluated for agreement by Cohen's kappa statistic.
RESULTS
The inter-rater reliability between retina specialists reading the SS-OCT images was 97.9% (κ = 0.957). Agreement on PVD status between SS-OCT and biomicroscopy was 85.3% (κ = 0.711). Agreement between SS-OCT and B-scan ultrasound was 83.2% (κ = 0.667). Agreement between B-scan ultrasound and biomicroscopy was 87.4% (κ = 0.743).
CONCLUSION
For the diagnosis of complete PVD, SS-OCT allows for high accuracy and agreement between graders.
背景
生物显微镜检查、B 超超声成像和 SD-OCT 都是用于描述玻璃体后脱离（PVD）的方法。我们的目的是评估 SS-OCT 诊断 PVD 的准确性。
方法
这项前瞻性观察性研究对 49 例患者的 95 只眼睛进行了生物显微镜检查、B 超超声检查和 SS-OCT 检查，以确定是否存在完全性 PVD。所有 SS-OCT 图像均由两名视网膜专家（RWSC、ZM）进行评估。采用 Cohen's kappa 统计量评估这三种诊断方法的一致性。
结果
阅读 SS-OCT 图像的视网膜专家之间的评分者间可靠性为 97.9%（κ = 0.957）。SS-OCT 与生物显微镜检查在 PVD 状态上的一致性为 85.3%（κ = 0.711）。SS-OCT 与 B 超超声检查之间的一致性为 83.2%（κ = 0.667）。B 超超声检查与生物显微镜检查之间的一致性为 87.4%（κ = 0.743）。
结论
对于完全性 PVD 的诊断，SS-OCT 具有较高的准确性，且分级者之间的一致性良好。
