研究目的: |
本研究旨在基于大样本回顾性纵向临床数据,构建一个实用、精准、高效的儿童青少年屈光状态预测模型。 1. 基线精准预测(Static Mode): 在首诊无历史数据场景下,利用IOL-Master生物测量参数(AL、K、ACD等)结合大样本人群固定效应,实现对小瞳/睫状肌麻痹后屈光度(包括不同药物)的范围预测; 2. 动态修正与校准(Dynamic Mode): 在复查场景下,模型通过自动整合个体的纵向随访数据(如眼轴增长速率、瞳距增长等),对个体预测结果进行个性化校准。 3. 临床转化: 最终将该核心算法封装为眼部生物测量设备的内置程序或临床桌面测算软件,替代传统图表以及人工计算,为临床提供全病程、即时响应的无创辅助诊断工具。 |

Objectives of Study: |
This study aims to construct a practical, accurate, and efficient prediction model for the refractive status of children and adolescents, based on large-scale retrospective longitudinal clinical data. The specific objectives are as follows: 1. Baseline Precise Prediction (Static Mode): In initial visit scenarios where historical data is unavailable, the model utilizes IOL-Master biometric parameters (e.g., AL, K, ACD) combined with population-based fixed effects to predict the range of refractive error under both non-cycloplegic and cycloplegic conditions (accounting for various mydriatic agents).2. Dynamic Correction and Calibration (Dynamic Mode): In follow-up scenarios, the model automatically integrates individual longitudinal follow-up data (such as the rate of axial length elongation and interpupillary distance growth) to perform personalized calibration of the prediction results.3. Clinical Application: Ultimately, the core algorithm will be encapsulated as a built-in program for ocular biometry devices or as clinical desktop software. This seeks to replace traditional charts and manual calculations, providing clinicians with a non-invasive auxiliary diagnostic tool that offers real-time responses throughout the entire clinical course. |

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
Data will be de-identified immediately upon extraction. Direct personal identifiers, such as patient names and hospitalization numbers, will be masked, and only research codes will be retained. Multiple visit records for the same patient across different time points will be linked via a unique patient ID to establish a longitudinal data chain. All data will be stored on a dedicated, encrypted computer within the department, with access restricted solely to authorized research personnel. |
