Anatomy & Education
Anatomy Overview
Understanding the anatomy of the eyelids, tear drainage system, and orbit is fundamental to oculoplastic surgery. Each guide below provides in-depth detail on the structures relevant to cosmetic and reconstructive procedures around the eye.
Eyelid Anatomy
Explore the layers, muscles, tendons, and structures of the upper and lower eyelids — including the levator complex, orbicularis oculi, tarsal plates, and canthal tendons.
