To describe features of vitreomacular traction syndrome (VMT) on three-dimensional (3D) spectral-domain optical coherence tomography (SD OCT).
Eighteen eyes of 18 patients with VMT were diagnosed by SD OCT. SD OCT images were obtained and retrospectively analyzed. These VMT cases were defined as focal type or broad type by the region of the vitreous attachment to the macula. The relationship between the logMAR best corrected visual acuity (BCVA) and the retinal thickness of macular fovea was evaluated by linear regression analysis.
SD OCT provided detailed 3D images of VMT and revealed information about the extent of vitreomacular traction. Focal VMT was seen in 14 eyes. Broad VMT was seen in four eyes. Eight cases had concurrent epiretinal membrane in the areas surrounding the fovea. Two cases had concurrent full thickness macular hole and two cases had concurrent lamellar macular hole. LogMAR BCVA correlated with the retinal thickness of macular fovea (r = 0.616, P = 0.007, linear regression analysis).
SD OCT allows good visualization of the architectural morphology of the vitreous and retina in vitreomacular traction syndrome. It is useful and irreplaceable for the diagnosis and follow-up of VMT.
描述三维(3D)光谱域光学相干断层扫描(SD OCT)下玻璃体黄斑牵拉综合征(VMT)的特征。
18例VMT患者的18只眼通过SD OCT进行诊断。获取SD OCT图像并进行回顾性分析。根据玻璃体与黄斑的附着区域,将这些VMT病例定义为局灶型或广泛型。通过线性回归分析评估logMAR最佳矫正视力(BCVA)与黄斑中心凹视网膜厚度之间的关系。
SD OCT提供了VMT的详细3D图像,并揭示了玻璃体黄斑牵拉的程度信息。14只眼为局灶性VMT。4只眼为广泛性VMT。8例在黄斑中心凹周围区域并发视网膜前膜。2例并发全层黄斑裂孔,2例并发板层黄斑裂孔。LogMAR BCVA与黄斑中心凹视网膜厚度相关(r = 0.616,P = 0.007,线性回归分析)。
SD OCT能很好地显示玻璃体黄斑牵拉综合征中玻璃体和视网膜的结构形态。它对VMT的诊断和随访有用且不可替代。
