To evaluate, in an experimental study, an interactive, computer-based teaching procedure for kinetic perimetry that incorporates an evaluation system for scoring examination technique.
K-Train was developed and based on the original user interface of the new semi-automated kinetic perimetry (SKP) feature of the OCTOPUS 101 perimeter (HAAG-STREIT, Koeniz, Switzerland). The trainer creates a 3D individual "hill of vision" for a specific pathology and the trainee can individually select target characteristics and independently define origin, end and direction of each kinetic stimulus with the help of vectors. Quality of the perimetric examination can be quantitatively assessed by the ratio of intersection area and union area of the trainee's result and the related trainer-defined original isopter. This ratio and other parameters are used to define a score of "perimetric quality". The general acceptance of K-Train was assessed in 30 participants in two perimetric courses. The success rate was examined by comparing the scores before and after a perimetric training session.
The K-Train course was graded by the participants with an average score of 1.35 (range 1-3) in a scoring system ranging from 1=excellent to 6=unsatisfactory. The average perimetric quality score increased from 48 before to 59 (max. 100) after the training (27 trainees) indicating that K-Train was able to achieve and also verify a considerable success rate.
The acceptance of K-Train, a computer-based, interactive tool that allows for certification, education and quality control of kinetic perimetry, is high. K-Train is capable of improving a trainee's individual performance in kinetic perimetry and of verifying this by an appropriate scoring system.
在一项实验研究中评估一种基于计算机的交互式动态视野检查教学程序，该程序包含一个用于对检查技术进行评分的评估系统。
K-Train是在OCTOPUS 101视野计（瑞士科尼茨的HAAG-STREIT公司）新的半自动动态视野检查（SKP）功能的原始用户界面基础上开发的。培训师为特定病理情况创建一个三维个体“视野山丘”，学员可以借助向量单独选择目标特征，并独立定义每个动态刺激的起始点、终点和方向。通过学员结果与培训师定义的相关原始等视线的交集面积与并集面积之比，可以定量评估视野检查的质量。该比例和其他参数用于定义“视野质量”分数。在两个视野检查课程中，对30名参与者评估了K-Train的总体接受度。通过比较视野训练前后的分数来检验成功率。
在1（优秀）至6（不满意）的评分系统中，参与者对K-Train课程的平均评分为1.35（范围为1 - 3）。训练后（27名学员），平均视野质量分数从之前的48分提高到59分（满分100分），表明K-Train能够实现并验证相当高的成功率。
K-Train作为一种基于计算机的交互式工具，可用于动态视野检查的认证、教育和质量控制，其接受度很高。K-Train能够提高学员在动态视野检查中的个人表现，并通过适当的评分系统进行验证。
