We prospectively studied 29 consecutive eyes with proliferative diabetic retinopathy that showed media clear enough to enable characterization of vitreoretinal relationships by biomicroscopy. Vitreoretinal relationships were also determined by contact B-scan ultrasound. With both techniques, these relationships were documented by photographs and drawings. Biomicroscopy showed complete posterior vitreous detachment (PVD) in 4 eyes (14%), partial PVD in 18 (62%), and no PVD in 7 (24%). Ultrasound examination revealed complete PVD in 4 eyes (14%), partial PVD in 19 (66%), and no PVD in 6 (21%). The results we obtained using ultrasound agreed significantly with those obtained by biomicroscopy [Cohen's kappa = 0.93, 95% confidence interval = (0.80, 1.06)]. Ultrasound detected vitreous changes more easily than biomicroscopy when mild media opacities were present and when the equatorial areas of the globe were examined. Results suggest that ultrasound is adequate to determine vitreoretinal relationships in eyes with clear media and that it is a good alternative to biomicroscopy in eyes with significant media opacities.
我们对29例患有增殖性糖尿病视网膜病变的连续病例进行了前瞻性研究，这些病例的眼内介质足够清晰，能够通过生物显微镜对玻璃体视网膜关系进行特征描述。还通过接触式B超超声检查来确定玻璃体视网膜关系。两种技术均通过照片和绘图记录这些关系。生物显微镜检查显示，4只眼（14%）出现完全性玻璃体后脱离（PVD），18只眼（62%）出现部分性PVD，7只眼（24%）未出现PVD。超声检查显示，4只眼（14%）出现完全性PVD，19只眼（66%）出现部分性PVD，6只眼（21%）未出现PVD。我们使用超声获得的结果与通过生物显微镜获得的结果显著一致[科恩kappa系数 = 0.93，95%置信区间 = (0.80, 1.06)]。当存在轻度介质混浊以及检查眼球赤道区域时，超声比生物显微镜更容易检测到玻璃体变化。结果表明，超声足以确定介质清晰的眼中的玻璃体视网膜关系，并且在介质混浊明显的眼中，它是生物显微镜的良好替代方法。
