Vertical corneal striae distributed across the posterior cornea are one of the objective signs of clinically unacceptable corneal swelling (greater than 6%) resulting from contact lens wear. This study reports that corneal striae are repeatable both in configuration and location with different levels of hypoxia. In most instances entoptic phenomena result from the presence of these lines. The results suggest that the healthy, avascular, transparent cornea has certain localised areas in its anatomical structure which may give rise to bundles of collagen fibres being made visible objectively and subjectively during conditions of corneal swelling.
分布于角膜后部的垂直角膜条纹是因佩戴隐形眼镜导致临床上不可接受的角膜肿胀（大于6%）的客观体征之一。本研究报告称，在不同程度的缺氧情况下，角膜条纹在形态和位置上都是可重复的。在大多数情况下，视内现象是由这些条纹的存在引起的。结果表明，健康、无血管、透明的角膜在其解剖结构中有某些局部区域，在角膜肿胀的情况下，这些区域可能会使胶原纤维束在客观和主观上都变得可见。
