研究目的: |
本研究旨在开发并验证一种基于多模态数据融合的深度学习模型,准确预测儿童散瞳后屈光度,并评估模型在眼球发育过程中的预测稳定性。具体目标包括:构建整合非散瞳验光度数、年龄、性别等临床信息的基线预测模型;基于眼轴长度、角膜曲率、前房深度、晶状体厚度等生物测量参数,特别是利用SRK/T公式计算的晶状体前表面曲率半径等特征,构建生物测量增强模型,量化晶状体调节作用对预测精度的贡献;开发基于卷积神经网络的眼底影像特征提取模块,自动识别豹纹状眼底、视盘椭圆度等形态学特征,构建多模态融合模型,识别屈光度与眼底结构不匹配的高危儿童;在具有1年随访数据的儿童队列中验证模型的纵向预测稳定性;通过可解释性分析揭示各类特征的相对重要性,最终建立适用于临床门诊、学校筛查和流行病学研究的儿童散瞳屈光度预测系统。 |

Objectives of Study: |
This study aims to develop and validate a deep learning model based on multimodal data fusion for the accurate prediction of cycloplegic refractive error in children, and to evaluate the predictive stability of the model during ocular development. The specific objectives are as follows: to construct a baseline prediction model integrating clinical information such as non-cycloplegic refractive values, age, and gender; to establish a biometric-enhanced model using ocular biometric parameters including axial length, corneal curvature, anterior chamber depth, and lens thickness, particularly incorporating features such as the anterior lens surface curvature radius calculated via the SRK/T formula, so as to quantify the contribution of lens accommodation to prediction accuracy; to develop a convolutional neural network-based fundus image feature extraction module to automatically identify morphological characteristics such as tessellated fundus and optic disc ellipticity, and construct a multimodal fusion model to screen high-risk children with mismatched refractive status and fundus structure; to validate the longitudinal predictive stability of the model in a pediatric cohort with 1-year follow-up data; to reveal the relative importance of various features through interpretability analysis, and ultimately establish a prediction system for cycloplegic refractive error in children applicable to clinical outpatient settings, school screening, and epidemiological research. |
