PURPOSE
To compare the specificity of diagnosing posterior vitreous detachment (PVD) using preoperative optical coherence tomography (OCT) versus intraoperative triamcinolone acetonide (TA) staining in patients undergoing vitrectomy.
PATIENTS AND METHODS
This retrospective cohort study included patients undergoing pars plana vitrectomy for diverse retinal pathologies. Intraoperatively, surgeons evaluated the posterior hyaloid status with TA staining and compared it with preoperative OCT findings.
RESULTS
One hundred six patients underwent intraoperative assessments of posterior hyaloid status, with 72% (76/106) of the eyes showing positive staining. Sixty-two patients had also undergone preoperative OCT. Of the patients diagnosed with PVD on preoperative OCT, 50% (15/30) showed positive TA staining intraoperatively. The sensitivity of preoperative OCT assessment was 83.3%, and its specificity was 65.9%.
CONCLUSION
Preoperative OCT imaging is associated with lower sensitivity and specificity for diagnosing PVD when compared to intraoperative TA staining.
目的
比较在接受玻璃体切除术的患者中，术前光学相干断层扫描（OCT）与术中曲安奈德（TA）染色诊断玻璃体后脱离（PVD）的特异性。
患者与方法
这项回顾性队列研究纳入了因各种视网膜病变接受玻璃体切除术的患者。术中，外科医生通过TA染色评估玻璃体后皮质状态，并将其与术前OCT检查结果进行比较。
结果
106例患者接受了术中玻璃体后皮质状态评估，其中72%（76/106）的眼睛染色呈阳性。62例患者也进行了术前OCT检查。在术前OCT诊断为PVD的患者中，50%（15/30）术中TA染色呈阳性。术前OCT评估的敏感性为83.3%，特异性为65.9%。
结论
与术中TA染色相比，术前OCT成像诊断PVD的敏感性和特异性较低。
