使用 E1 Bayadi-Kajiura 透镜研究了患有获得性视网膜劈裂病的50只眼(34名病人)。发现患有本病的眼,其部份性玻璃体后脱离的患病率明显多于正常眼(P<0.001)。所有有部份性玻璃体后脱离的眼均见到在劈裂区有玻璃体粘连。然而,完全性玻璃体后脱离的患病率在劈裂眼比对照眼低(P<0.05)。虽然引起获得性视网膜劈裂症的因素尚未清楚,本研究显示了部分性玻璃体后脱离伴玻璃体粘连在视网膜劈裂症的病因中的重要性。 Fifty eyes (34 patients) with acquired retinal splitting disease were studied using an E1 Bayadi-Kajiura lens. The prevalence of partial posterior vitreous detachment was significantly higher in eyes with this disease than in normal eyes (P <0.001). All eyes with partial posterior vitreous detachment showed vitreous adhesions in the cleavage zone. However, the prevalence of complete posterior vitreous detachment was lower in the splitting eyes than in the control eyes (P <0.05). Although the factors that cause acquired retinopathy are not clear, this study shows the importance of partial posterior vitreous detachment with vitreous adhesions in the etiology of retinoschisis.
