This study was designed to determine criteria of normality of peri-ungual capillaroscopy of the toes. The equipment used was a Leitz microscope fitted with a 150 W cold light lighting system. The study involved a population of 84 healthy individuals. Intra-judge and inter-judge concordance tests were carried out, indicating results to be reliable. Capillaroscopy of the hand (reference norms) and capillaroscopy of the feet (with the subject sitting with the legs hanging) were carried out in each case. Examination of the feet was perfectly possible in only 87% of cases. Results showed that the majority of criteria of normality of peri-ungual capillaroscopy of the hand were also found in the foot, whilst others were different (number of capillary loops per millimetre which was on average less, the number of minor dystrophic forms which could be very great, the length of capillary loops which were slightly shorter and background colour which was paler). Finally, certain were not found (peri-capillary haziness more frequent because of physiological oedema and frequent irregularity in the distribution of capillary loops). No major dystrophy was seen and traumatic hemorrhages were no more frequent in the foot than in the hand.
本研究旨在确定趾甲周毛细血管镜检查的正常标准。所用设备为配备150W冷光照明系统的徕卡显微镜。该研究涉及84名健康个体。进行了判断内和判断间一致性测试，结果表明结果可靠。每种情况下均进行了手部毛细血管镜检查（参考标准）和足部毛细血管镜检查（受试者坐着，双腿下垂）。仅在87%的病例中能够完美地检查足部。结果显示，手部甲周毛细血管镜检查的大多数正常标准在足部也能发现，而其他标准则不同（每毫米毛细血管袢数量平均较少、微小营养不良形态数量可能很多、毛细血管袢长度略短以及背景颜色较淡）。最后，某些情况在足部未发现（由于生理性水肿，毛细血管周围模糊更常见，且毛细血管袢分布频繁不规则）。未观察到严重营养不良，足部创伤性出血并不比手部更频繁。
