Enucleated human eyes were banded with metal and silicone bands to produce reductions in their diameter of 2 mm and 4 mm. The ocular rigidity produced by each banding material at each diameter was measured in the pressure range of 10 mmHg to 40 mmHg. Metal bands produced mild reductions in ocular rigidity that were significantly (P less than 0.05 to 0.01) lower than the control ocular rigidities in some pressure ranges. Silicone bands produced large reductions in ocular rigidity that were significantly (P less than 0.01) lower than ocular rigidities observed in metal-banded or control conditions in all pressure ranges. The influence of the elastic silicone banding material on ocular rigidity was greater than the influence of altered shape and wall stress that occurred with metal banding.
将摘除的人眼用金属带和硅胶带绑扎，使其直径分别减小2毫米和4毫米。在10毫米汞柱至40毫米汞柱的压力范围内，测量每种绑扎材料在每种直径下产生的眼内硬度。金属带使眼内硬度略有降低，在某些压力范围内显著低于对照眼内硬度（P小于0.05至0.01）。硅胶带使眼内硬度大幅降低，在所有压力范围内均显著低于金属带绑扎或对照条件下观察到的眼内硬度（P小于0.01）。弹性硅胶绑扎材料对眼内硬度的影响大于金属绑扎时形状改变和壁应力产生的影响。
