Palmar dermatoglyphs were studied in 38 patients with lens dislocation. The patients were distributed into three groups: Marfan syndrome, mild Marfan syndrome, isolated lens dislocation. Marked arachnodacytyly was observed in the first group. In these patients increase in finger length was positively correlated with the ridge count. Moderate increase in finger length and ridge count was observed in the second group. The relative finger length was lower in patients with isolated lens dislocation than in unaffected persons, though the ridge count did not differ from the control. The relations noted between the finger length and ridge count in Marfan syndrome are in agreement with the suggestion that these two parameters are determined by common cause, namely, the morphogenetic gradient in digital primordia.
对38例晶状体脱位患者的手掌皮纹进行了研究。患者分为三组：马凡综合征、轻度马凡综合征、孤立性晶状体脱位。在第一组中观察到明显的蜘蛛指样畸形。在这些患者中，手指长度的增加与嵴纹计数呈正相关。在第二组中观察到手指长度和嵴纹计数有中度增加。孤立性晶状体脱位患者的相对手指长度低于未受影响者，尽管嵴纹计数与对照组无差异。马凡综合征中手指长度与嵴纹计数之间的关系与这两个参数由共同原因即指原基中的形态发生梯度决定的观点一致。
