A new screening technique for neonatal jaundice is proposed exploiting the yellow discoloration in the sclera. It involves taking digital photographs of newborn infants' eyes (n = 110) and processing the pixel colour values of the sclera to predict the total serum bilirubin (TSB) levels. This technique has linear and rank correlation coefficients of 0.75 and 0.72 (both p<0.01) with the measured TSB. The mean difference ( ± SD) is 0.00 ± 41.60 µmol/l. The receiver operating characteristic curve shows that this technique can identify subjects with TSB above 205 µmol/l with sensitivity of 1.00 and specificity of 0.50, showing its potential as a screening device.
一种利用巩膜黄染现象的新生儿黄疸筛查新技术被提出来了。该技术包括对110名新生儿的眼睛进行数码拍照,并处理巩膜的像素颜色值以预测总血清胆红素(TSB)水平。这项技术与测得的TSB的线性相关系数和秩相关系数分别为0.75和0.72(两者p<0.01)。平均差值(±标准差)为0.00±41.60µmol/l。受试者工作特征曲线表明,该技术能够以1.00的灵敏度和0.50的特异性识别TSB高于205µmol/l的受试者,显示出其作为一种筛查设备的潜力。
