Using a slit-lamp biomicroscope mounted Cochet-Bonnet aesthesiometer, the touch sensitivity of the eyelid margin and palpebral conjunctiva was determined for both upper and lower lids in 30 subjects. Thresholds for the occlusal surface of the lid, the marginal angle and the middle of the tarsus were measured centrally. A significantly higher touch sensitivity was found for the marginal zone compared with the occlusal surface, and tarsal conjunctival sensitivity was substantially the lowest. The occlusal and marginal zones of the lower lid displayed a significantly higher touch sensitivity than the upper lid but the tarsal sensitivity of the two lids was similar. The sharp peaking of sensitivity at the leading edge of each eyelid provides a mechanism for the detection of superficial foreign bodies and presumably augments the protective role of the cornea. A large inter-subject variation in marginal touch sensitivity was found which may explain individual variation in contact lens adaptation.
使用安装了科谢 - 博内眼压计的裂隙灯生物显微镜，对30名受试者的上下眼睑睑缘和睑结膜的触觉敏感性进行了测定。在中央测量眼睑咬合面、边缘角和睑板中部的阈值。发现边缘区的触觉敏感性明显高于咬合面，睑结膜敏感性基本最低。下眼睑的咬合区和边缘区显示出比上眼睑明显更高的触觉敏感性，但两个眼睑的睑板敏感性相似。每个眼睑前缘的敏感性急剧峰值为检测浅表异物提供了一种机制，并且可能增强了角膜的保护作用。发现边缘触觉敏感性存在较大的个体间差异，这可能解释了隐形眼镜适应性的个体差异。
