A comprehensive assessment of visual functioning at an early age is important not only for identifying and defining visual impairment but also for planning personalized rehabilitation programs based on the visual diagnosis. Since existing tools to evaluate visual functioning present some important limitations (e.g., they are based on qualitative reports, they do not take into account environmental adaptations of visual testing or they have not been formally validated as clinical instruments), the present work has the main aim to propose a new clinical tool () to detect and define visual disorders at an early age.
The Visual Function Score was administered to one hundred visually impaired children (age range 4 months to 17.75 years old) in the form of a professional-reported protocol for a total of 51 items, each of which is assigned a score from 1 to 9 (or from 0 to 9 in some specific cases). The VFS produces three sub-scores and a global score (from 0 to 100), resulting in a quantitative evaluation of visual functioning.
The VFS can detect the well-known differences between different types of visual impairment (cerebral, oculomotor, and peripheral or grouped as central and peripheral) and takes into account different environments in the definition of a quantitative score of visual functioning.
Overall, the use of a quantitative tool to evaluate visual functions and functional vision such as the VFS would be fundamental to monitor the progresses of patients over time in response to rehabilitation interventions.
早期对视觉功能进行全面评估不仅对于识别和界定视力障碍很重要，而且对于根据视觉诊断制定个性化康复计划也很重要。由于现有的评估视觉功能的工具存在一些重要局限性（例如，它们基于定性报告，未考虑视觉测试的环境适应性，或者未被正式验证为临床工具），因此本研究的主要目的是提出一种新的临床工具（），用于在早期检测和界定视觉障碍。
对100名视力障碍儿童（年龄范围为4个月至17.75岁）采用专业报告方案的形式进行视觉功能评分，共51项，每项的评分从1到9（在某些特定情况下为0到9）。视觉功能评分产生三个子评分和一个总评分（从0到100），从而对视觉功能进行定量评估。
视觉功能评分可以检测出不同类型视力障碍（大脑性、动眼性和周边性或分为中枢性和周边性）之间的已知差异，并在定义视觉功能定量评分时考虑不同环境。
总体而言，使用像视觉功能评分这样的定量工具来评估视觉功能和功能性视力对于监测患者随时间推移对康复干预的反应进展至关重要。
