Abstract

Ocular dimensions and lens refractive properties were studied in enucleated eyes from 5-day old chicken (Gallus domesticus). Measurements were made in frozen hemisections and in fresh eyes sectioned through a para-equatorial plane. In these specimens, lens properties were examined after systematical removal of the vitreal mass. This procedure caused significant changes in lens diameter and refractive properties. Our data indicate that avian lens shape could be controlled by vitreal pressure and/or scleral support.

摘要

对5日龄家鸡（Gallus domesticus）摘除的眼球进行了眼尺寸和晶状体屈光特性研究。在冷冻半切标本以及沿赤道旁平面剖切的新鲜眼球中进行测量。在这些标本中，在系统移除玻璃体团块后检查晶状体特性。此操作导致晶状体直径和屈光特性发生显著变化。我们的数据表明，禽类晶状体形状可能受玻璃体压力和/或巩膜支撑的控制。
