Abstract

The iris is derived from interaction between neural crest tissue and the adjacent neuroectoderm of the optic cup. Developmental anomalies of the equine iris are common, and include congenital miosis, iris cysts, various manifestations of iris hypoplasia, heterochromia, and persistent pupillary membrane remnants. They may be found alone or in combination with other ocular defects.

摘要

虹膜由神经嵴组织与视杯相邻的神经外胚层相互作用发育而来。马的虹膜发育异常很常见，包括先天性瞳孔缩小、虹膜囊肿、虹膜发育不全的各种表现、异色症以及持续性瞳孔膜残余。它们可能单独出现，也可能与其他眼部缺陷同时存在。
