Tractional retinoschisis and tractional retinal detachment are both complications of proliferative diabetic retinopathy. The two conditions are frequently confused because they are similar in diagnostic features. We determined the respective incidence of tractional retinoschisis and tractional retinal detachment in 200 eyes with tractional elevations of the retina in patients with diabetes. In 39 eyes, the diagnosis was unequivocally tractional retinoschisis because the retinal elevation maintained its concave contour despite the development of retinal holes. In 65 eyes, tractional retinal detachment was diagnosed with equal certainty, either because pigment lines were present or because the elevation, after a retinal hole developed, rapidly became convex and extended to the ora serrata. The remaining 96 eyes, in which retinal holes or pigment lines were absent, were classified by other features that had been tested for significance in the already diagnosed eyes. On that basis, the diagnosis was retinoschisis in 46 eyes and retinal detachment in 50 eyes.
牵拉性视网膜劈裂症和牵拉性视网膜脱离均为增殖性糖尿病视网膜病变的并发症。这两种情况常被混淆，因为它们在诊断特征上相似。我们确定了200例糖尿病患者视网膜有牵拉性抬高的眼中牵拉性视网膜劈裂症和牵拉性视网膜脱离各自的发生率。在39只眼中，诊断明确为牵拉性视网膜劈裂症，因为尽管出现了视网膜裂孔，但视网膜抬高仍保持其凹面轮廓。在65只眼中，同样明确诊断为牵拉性视网膜脱离，这要么是因为存在色素线，要么是因为在视网膜裂孔形成后，抬高迅速变为凸面并延伸至锯齿缘。其余96只眼既没有视网膜裂孔也没有色素线，根据在已确诊的眼中经检验具有显著性的其他特征进行分类。在此基础上，46只眼诊断为视网膜劈裂症，50只眼诊断为视网膜脱离。
