OBJECTIVE
No method of grading visual field (VF) defects has been widely accepted throughout the glaucoma community. The SCHEIE (Systematic Classification of Humphrey visual fields-Easy Interpretation and Evaluation) grading system for glaucomatous visual fields was created to convey qualitative and quantitative information regarding visual field defects in an objective, reproducible, and easily applicable manner for research purposes.
METHODS
The SCHEIE grading system is composed of a qualitative and quantitative score. The qualitative score consists of designation in one or more of the following categories: normal, central scotoma, paracentral scotoma, paracentral crescent, temporal quadrant, nasal quadrant, peripheral arcuate defect, expansive arcuate, or altitudinal defect. The quantitative component incorporates the Humphrey visual field index (VFI), location of visual defects for superior and inferior hemifields, and blind spot involvement. Accuracy and speed at grading using the qualitative and quantitative components was calculated for non-physician graders.
RESULTS
Graders had a median accuracy of 96.67% for their qualitative scores and a median accuracy of 98.75% for their quantitative scores. Graders took a mean of 56 seconds per visual field to assign a qualitative score and 20 seconds per visual field to assign a quantitative score.
CONCLUSION
The SCHEIE grading system is a reproducible tool that combines qualitative and quantitative measurements to grade glaucomatous visual field defects. The system aims to standardize clinical staging and to make specific visual field defects more easily identifiable. Specific patterns of visual field loss may also be associated with genetic variants in future genetic analysis.

SCHEIE 视野分级系统。
目的 目前尚无一种对视野 (VF) 缺陷进行分级的方法已被青光眼界广泛接受。 SCHEIE(汉弗莱视野系统分类 - 简易解释和评估)青光眼视野分级系统旨在以客观、可重复且易于应用的方式传达有关视野缺陷的定性和定量信息,以用于研究目的。方法 SCHEIE 评分系统由定性评分和定量评分组成。定性评分由以下一种或多种类别组成:正常、中央暗点、旁中央暗点、旁中央新月形、颞象限、鼻象限、外周弓形缺损、扩张性弓形或高度缺损。定量部分包括汉弗莱视野指数 (VFI)、上半视野和下半视野的视觉缺陷位置以及盲点参与情况。计算非医师分级人员使用定性和定量成分进行分级的准确性和速度。结果 评分者的定性分数的中位准确度为 96.67%,定量分数的中位准确度为 98.75%。评分者平均每个视野需要 56 秒来分配定性分数,每个视野平均需要 20 秒来分配定量分数。结论 SCHEIE 分级系统是一种可重复的工具,结合定性和定量测量来对青光眼视野缺陷进行分级。该系统旨在标准化临床分期,并使特定的视野缺陷更容易识别。视野丧失的特定模式也可能与未来遗传分析中的遗传变异有关。
