A group of eighteen patients was followed prospectively to document the development and natural history of collateral vessels. A second group of 42 patients was examined on a single occasion to provide a survey of the incidence and associations of collaterals. The time of appearance of collaterals varied between 2 and 8 months. The highest incidence of collaterals was in the macular vein occlusions. An increase in collateral vessel formation was seen where there was failure of recanalization of the occluded vein. No significance in the incidence of collaterals was seen in relation to age, site of obstruction, or hypertension. However, an increase in the incidence of collaterals was seen with time.
对一组18名患者进行前瞻性跟踪，以记录侧支血管的发展情况和自然病程。对另一组42名患者进行了一次检查，以调查侧支血管的发生率及其相关因素。侧支血管出现的时间在2至8个月之间。侧支血管发生率最高的是黄斑静脉阻塞。在阻塞静脉再通失败的情况下，可见侧支血管形成增加。侧支血管的发生率在年龄、阻塞部位或高血压方面无显著差异。然而，随着时间的推移，侧支血管的发生率有所增加。
