Study Notes
Eye Development
- The eyes are derived from the neural ectoderm during development.
- The development of the eye becomes evident at approximately 22-23 days' gestation.
- The optic grooves eventually develop into the optic vesicles.
- The optic vesicle converts into the optic cup at approximately 25-26 days' gestation.
- The ventral part of the optic stalk develops into the optic nerve during development.
