Summary
Eye development in the human embryo begins approximately at 22 days into gestational development and continues through the 10th gestational week. Rudimentary ocular organs are formed by both the mesoderm and ectoderm layers of the blastoderm. The retina, ciliary body, optic nerves, and iris are derived from neuroepithelium. The lens, eyelid, and corneal epithelium are formed from surface ectoderm. The sclera, vasculature, ocular muscles, vitreous, and corneal endothelium and stroma develop from the extracellular mesenchyme (Table 25.1) [1, 2].
