To investigate the prevalence of venous collaterals after branch and central retinal vein occlusion, assess the association of venous collaterals with other clinical features (including visual acuity), and determine if treatment with intravitreal corticosteroids influences the development of new venous collaterals.
Review of data from two multicenter randomized clinical trials in the Standard of Care versus COrticosteroid for REtinal Vein Occlusion (SCORE) Study.
Statistically significant associations of venous collaterals and visual acuity at baseline or at follow-up were not found. Treatment with intravitreal triamcinolone acetonide did not appear to influence the development of venous collaterals.
In contrast to some previous reports, development of venous collaterals did not demonstrate an independent association with visual acuity in eyes with branch retinal vein occlusion or central retinal vein occlusion in the SCORE Study. Intravitreal steroid effects do not appear to influence the development of venous collaterals.
调查分支静脉和中央视网膜静脉阻塞后静脉侧支的发生率,评估静脉侧支与其他临床特征(包括视力)的关系,并确定玻璃体内皮质类固醇治疗是否会影响新静脉侧支的形成。
对标准治疗与皮质类固醇治疗视网膜静脉阻塞的多中心随机临床试验(SCORE 研究)中的数据进行回顾。
未发现静脉侧支和基线或随访时视力之间存在统计学显著关联。玻璃体内曲安奈德治疗似乎并未影响静脉侧支的形成。
与一些先前的报告相反,在 SCORE 研究中,分支视网膜静脉阻塞或中央视网膜静脉阻塞眼的静脉侧支形成与视力之间并未显示出独立的关联。玻璃体内类固醇的作用似乎不会影响静脉侧支的形成。
