The choroid is the middle, vascular coat of the eye which resides between the sclera and the retina. Early in development the choroid fissure is a groove that extends along the ventral aspect of the optic stalk. In effect, it is a continuation of the invagination that forms the optic cup during early development in amniotes. For a period of time this groove extends to the closing lips of the optic cup. During development it is through the choroid fissure that the retinal vessels enter and leave the eye. While optic neural components (e.g. axons arising from retinal ganglion cells in the sensory retina) do not lie in the groove that is the choroid fissure, they do extend through the portions of the optic stalk that form the walls of the fissure. These axons will form the optic nerve. The fissure is eventually sealed when the lips of the optic cup, as well as the edges of the groove in the optic stalk, fuse. Failure of this fissure to close results in coloboma iridis.

• 眼胞が陥入して眼杯となり、同じく水晶体板も陥入して水晶体胞となる。眼胞の陥入は腹側縁でもおこり、眼杯裂を形成する。眼杯裂から硝子体動脈が侵入し眼球部に到達する。第7週頃に眼杯裂の両端(眼杯裂唇)が癒合する。眼杯の前方は閉鎖せず将来の瞳孔となる。
