Eyeball in a Section of the Skull, Lateral View

Description

Seen in lateral profile within a skull section, the ocular globe (bulbus oculi) occupies the anterior orbit, with the cornea and sclera forming the anterior and outer contour and the posterior pole directed toward the orbital apex. The optic nerve exits the posterior aspect of the eyeball and courses posteriorly toward the optic canal, while the rectus muscles form a muscular cone around it, inserting anterior to the equator of the globe. Superior and inferior oblique muscles arc around the globe to reach the posterior-lateral sclera, contrasting with the straighter medial and lateral rectus paths along the orbital walls. Bony landmarks of the orbit frame the scene, including the orbital rim and the medial and lateral walls that define the confined surgical corridor. A lateral orbital view clarifies relationships that drive common clinical problems. Trauma to the orbit frequently produces blowout fractures of the orbital floor (maxilla) with inferior rectus entrapment, vertical diplopia, and restricted upgaze, and this spatial layout makes the mechanism intuitive. The same perspective helps when teaching optic neuropathy and compressive lesions at the orbital apex, where swelling or mass effect can compromise the optic nerve and the motor nerves to the extraocular muscles within a tight bony funnel. Orientation matters. Small shifts explain big symptoms. Use this artwork for gross anatomy and neuroanatomy teaching on the orbit, extraocular muscle actions, and optic nerve course, or for ophthalmology and maxillofacial publications discussing diplopia after fracture repair, strabismus surgery planning, or orbital decompression approaches. It also suits patient-facing surgical consent materials that need accurate localization of the globe relative to the orbit and optic nerve.
