Tìm hiểu về khiếm khuyết ở Đồng tử - Iris coloboma

This video shows an iris coloboma defect in the eye. As you can see here, the iris muscle hasn’t completely formed in the infero-nasal portion of the globe. This gives the normally round pupil a “keyhole” appearance. If you look closely, you can even see the edge of the lens … which you can’t normally see. The left eye’s lens has a divot in it (a lens coloboma).
