They do, however, have quite distinct differences which will be further elucidated.
Second wave migrates more posteriorly to form the iris stroma and pupillary membrane.
Third wave migrates later between the epithelium and endothelium of the cornea to form the keratocytes of the stroma. By the fourth month of gestation the primordium of the trabecular meshwork is recognizable as a triangular mass of cells lying between the corneal endothelium and the stroma. The ocular component is typically bilateral and frequently associated with glaucoma. Correctopia is usually towards the major iris strand and iris atrophy 180 from it. The zone of differentiation between the corneal and anterior chamber angle endothelium is abnormally anterior and is associated with excessive basement membrane deposition which results in the prominent, anteriorly displaced Schwalbe's line.
