This review clarifies human orbital development from embryo to fetus, detailing the complex cellular interactions and signaling pathways that govern its formation. Understanding orbital morphogenesis is key to identifying links with congenital orbital diseases.
Area of Science:
- Developmental Biology
- Ophthalmology
- Embryology
Background:
- Orbital development is a complex process.
- Understanding its early stages is crucial for identifying disease links.
Purpose of the Study:
- To review current data on orbital development.
- To clarify controversies in early orbital morphogenesis.
- To detail orbital structure formation from embryo to fetus.
Main Methods:
- Extensive review of major studies on human orbital morphogenesis.
- Analysis of embryologic and fetal development of orbital structures.
- Inclusion of molecular biologic studies on signaling pathways.
Main Results:
- Orbital morphogenesis involves sequential, regulated events.
- Complex interactions between optic vesicles, neuroectoderm, neural crest cells, and mesoderm drive orbit formation.
- Development requires contributions from multiple cell populations.
Conclusions:
- Orbital development is a collaborative process involving diverse cell populations.
- Understanding orbital ontogenesis is vital for linking embryology to orbital disease.
