Optic Nerve Transection: A Model of Adult Neuron Apoptosis in the Central Nervous System
Published on: May 12, 2011
Summary
This case study details an intraorbital schwannoma, a rare tumor originating from the fifth cranial nerve. The primary symptom was exophthalmos (proptosis), necessitating discussion of diagnostic imaging and surgical options.
Area of Science:
- Ophthalmology
- Neurosurgery
- Oncology
Background:
- Intraorbital schwannomas are rare tumors arising from the Schwann cells of cranial nerves.
- The fifth cranial nerve (trigeminal nerve) is a common origin for intraorbital schwannomas.
Observation:
- A case presented with significant exophthalmos (11 mm protrusion) and restricted ocular motility.
- The tumor caused globe displacement, impacting visual function and appearance.
Findings:
- Exophthalmos is identified as the cardinal clinical manifestation of intraorbital schwannoma.
- Radiological modalities, including MRI and CT, are crucial for diagnosis and surgical planning.
Implications:
- Early diagnosis and appropriate management are essential for preserving vision and ocular function.
- Surgical intervention requires careful consideration of anatomical structures and potential complications.

01:27Cranial Bones: Lateral View
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

01:25Glaucoma: Overview
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...
01:17Accessory Structures of the Eye
Optical perception, or vision, is an extraordinary sense dependent on converting light signals received via the ocular organs. These organs, known as eyes, are securely positioned within the bony cavities of the skull, called orbits. The orbits serve a dual purpose: a protective shield for the ocular globes and a stable attachment point for the soft ocular tissues. The eye's external protective mechanisms include the eyelids, which are edged with lashes that act as a barrier against foreign...
