Corneal sensitivity has been studied in cluster headache (n = 38) and controls (n = 16). The patients were studied either during remission (n = 20), interparoxysmally in a bout (n = 17), or during attacks (spontaneously occurring attacks (n = 5) and nitroglycerin-provoked attacks (n = 6). For the measurements, a Cochet-Bonnet esthesiometer was utilized. This esthesiometer has a 6 cm long, adjustable nylon monofilament, which can be reduced in length by 0.5 cm at a time, the length of the filament determining the pressure exerted onto the corneal surface. All controls sensed the pressure at 6.0 cm filament length. In 5 cluster headache patients (remission, n = 4; cluster period, n = 1) a slight reduction in corneal sensitivity was found. No statistical difference was, however, found between any of the groups tested, and there was no asymmetry as far as averages were concerned.
对丛集性头痛患者（n = 38）和对照组（n = 16）的角膜敏感性进行了研究。对患者的研究分别在缓解期（n = 20）、发作间期（n = 17）或发作期间（自发发作（n = 5）和硝酸甘油诱发发作（n = 6））进行。测量时使用了科谢-博内眼压计。这种眼压计有一根6厘米长的可调节尼龙单丝，每次可缩短0.5厘米，单丝的长度决定施加在角膜表面的压力。所有对照组在单丝长度为6.0厘米时都能感觉到压力。在5例丛集性头痛患者中（缓解期，n = 4；丛集期，n = 1）发现角膜敏感性略有降低。然而，在任何测试组之间均未发现统计学差异，就平均值而言也没有不对称性。
