摘要：

Following the observation of comp sensory receptors concentrated within the palisade zone of the human conjunctiva, this study sought to measure limbal touch sensitivity using a Cochet-Bonnet aesthesiometer. Touch sensitivity was found to be significantly higher in the palisade zone compared with the adjacent conjunctiva. A comparison between temporal and inferior limbus showed a greater median sensitivity for the temporal zone. There was a significant reduction in touch sensitivity with age, but not with iris colour or contact lens wear. These data, showing a higher touch sensitivity for the palisade zone, provide indirect evidence for a role of complex nerve endings in mechanoreception.
