Accurate assessment of eyelid position and movement is vital in planning the surgical correction of ptosis. Conventional measurements taken using a millimeter ruler are considered the gold standard, although in young children this can be a difficult procedure. The authors have designed ptosis assessment spectacles with a measuring millimeter scale marked on the center of the lens to facilitate accurate assessment of eyelid position and function in children. The purpose of the study was to assess the accuracy and reproducibility of eyelid measurement using these ptosis assessment spectacles.
Fifty-two children aged 2-12 years were recruited in this study. Each child underwent 2 sets of measurements. The first was undertaken by an ophthalmologist in the conventional manner using a ruler, and the second set made with ptosis assessment spectacles. On each occasion the palpebral aperture, skin crease, and levator function were recorded in millimeters. A verbal analog scale was used to assess parent satisfaction with each method.
Clinically acceptable reproducibility was shown with the ruler and the spectacles for all measurements: palpebral aperture, skin crease, and levator function. Parents significantly preferred the glasses for measurement, as compared with the ruler (p < 0.05).
The spectacles are as accurate as conventional methods of measurement, but are easier to use. Children tolerate these spectacles well, and most parents preferred them to the ruler.
准确评估眼睑位置和运动对于上睑下垂的手术矫正至关重要。传统的测量方法是使用毫米尺进行，但对于幼儿来说，这可能是一项困难的操作。作者设计了带有毫米刻度标记的上睑下垂评估眼镜，以方便准确评估儿童的眼睑位置和功能。本研究的目的是评估使用这些上睑下垂评估眼镜进行眼睑测量的准确性和可重复性。
本研究纳入了 52 名 2-12 岁的儿童。每个孩子都进行了 2 组测量。第一组由眼科医生使用尺子进行传统测量，第二组使用上睑下垂评估眼镜进行测量。每次测量都记录了眼睑孔径、皮肤皱褶和提上睑肌功能的毫米数。使用口头模拟量表评估家长对每种方法的满意度。
尺子和眼镜在所有测量项目（眼睑孔径、皮肤皱褶和提上睑肌功能）上均表现出可接受的临床重复性。与尺子相比，家长明显更喜欢眼镜进行测量（p < 0.05）。
眼镜与传统测量方法一样准确，但更易于使用。儿童对这些眼镜的耐受性良好，大多数家长更喜欢使用眼镜而不是尺子。
