目的探讨红通道眼底成像在检测视网膜中央静脉阻塞(CRVO)眼缺血状态中的作用。对42眼CRVO患者行超宽视野(UWF)眼底成像。缺血组21只眼，非缺血组21只眼。11只缺血眼出现红斑。使用ImageJ软件将UWF图像分割为红色和绿色通道。当蒙面评分者检查时，彩色和红色通道图像被用来预测缺血的存在或不存在。分别计算A组(42只眼)、B组(32只眼)和C组(31只眼)的UWF图像检测缺血的敏感性和特异性。此外，使用线性混合模型来研究图像类型与每组预测精度之间的关系。A组与B组眼底彩色成像的灵敏度差异无统计学意义，而红通道成像的灵敏度A组与B组比较差异有统计学意义(P=0.031)。在A组和B组，预测的准确性与图像类型无关，但在C组，预测的准确性与图像类型显著相关(p=0.026)。与彩色眼底图像相比，UWF红色通道成像能够更准确地检测缺血状态，尤其是在非红斑性CRVO眼。
To examine the usefulness of red channel fundus imaging to detect the ischemic status in eyes with central retinal vein occlusion (CRVO). Ultra-widefield (UWF) fundus images were obtained from 42 eyes with CRVO. Twenty-one eyes were ischemic, and 21 eyes were non-ischemic. Rubeosis was found in 11 ischemic eyes. UWF images were split into red and green channels using ImageJ software. Both the color and red channel images were used to predict the presence or absence of ischemia when examined by masked graders. The sensitivity and specificity of UWF imagings for the detection of ischemia were calculated in Group A (total 42 eyes), Group B (32 eyes excluding non-rubeotic ischemic CRVO) and Group C (31 eyes excluding rubeotic ischemic CRVO), respectively. Moreover, a linear mixed model was conducted to investigate the relationship between the type of images and the accuracy of prediction in each group. No significant difference in the sensitivity of color fundus imaging was seen between Group A and Group B. By contrast, a significant difference in the sensitivity of red channel imaging was seen between Group A and Group B (p = 0.031). The accuracies of the predictions were not associated with the type of image in Group A and Group B, but were significantly associated in Group C (p = 0.026). UWF red channel imaging enabled more accurate detection of the ischemic status, compared with color fundus images, especially in non-rubeotic CRVO eyes.
