Eyes initially form laterally from the paired ectodermic optic placodes and migrate medially in the human embryo. In other animals such as birds and lizards, the eyes do not migrate and develop laterally on the head. The optic placodes become prominent at approximately Stage 14 of development.

Introduction

Eyes are an important sensory organ shared across many different species and allow organisms to gather useful visual information from their environment.

Research history

Development

Eyes initially form laterally from the paired ectodermic optic placodes and migrate medially in the human embryo. In other animals such as birds and lizards, the eyes do not migrate and develop laterally on the head. The optic placodes become prominent at approximately Stage 14 of development and contribute the lens to the eye.

Lens

The lens has its origin from the optic placode, which develops on the ectodermic surface of the embryo and migrates both medially and inwards into the embryo.
