The aim of this study was to detect clinical factors predictive of loss of visual acuity after treatment in order to develop a predictive model to help identify patients at risk of visual loss.
This was a retrospective review of patients who underwent interventional radiotherapy (brachytherapy) with Ru plaque for primary uveal melanoma. A predictive nomogram for visual acuity loss at 3 years from treatment was developed.
A total of 152 patients were selected for the study. The actuarial probability of conservation of 20/40 vision or better was 0.74 at 1 year, 0.59 at 3 years, and 0.54 at 5 years after treatment. Factors positively correlated with loss of visual acuity included: age at start of treatment (p=0.004) and longitudinal basal diameter (p=0.057), while distance of the posterior margin of the tumor from the foveola was inversely correlated (p=0.0007).
We identified risk factors affecting visual function and developed a predictive model and decision support tool (AVATAR nomogram).
本研究旨在发现治疗后视力丧失的预测因素,以制定预测模型,帮助识别有视力丧失风险的患者。
这是对接受放射性碘 125 粒子近距离放疗(腔内近距离放疗)治疗原发性脉络膜黑色素瘤的患者进行的回顾性研究。制定了治疗后 3 年视力丧失的预测列线图。
共选择了 152 名患者进行研究。治疗后 1 年、3 年和 5 年时,20/40 或更好视力保留的累积概率分别为 0.74、0.59 和 0.54。与视力丧失正相关的因素包括:治疗开始时的年龄(p=0.004)和纵向基底直径(p=0.057),而肿瘤后极距黄斑的距离呈负相关(p=0.0007)。
我们确定了影响视觉功能的危险因素,并制定了预测模型和决策支持工具(AVATAR 列线图)。
