Summary
A traumatic brain injury led to internuclear ophthalmoplegia in a young man. This rare condition, often caused by trauma, showed significant improvement over time.
Area of Science:
- Neuroscience
- Ophthalmology
- Trauma Surgery
Background:
- A 23-year-old male sustained a closed head injury from a fall, resulting in a C-7 burst fracture.
- A halo and halo vest were applied 9 hours post-injury for spinal stabilization.
Observation:
- The patient developed diplopia 21 hours after the accident.
- Neuro-ophthalmology evaluation revealed unilateral internuclear ophthalmoplegia.
- Brain MRI showed a small infarct in the inferior midbrain.
Findings:
- The patient experienced 90% improvement in internuclear ophthalmoplegia by 9.5 weeks.
- Literature review indicates traumatic internuclear ophthalmoplegia predominantly affects males (83.33%) with a mean age of 31.7.
- Common causes include motor vehicle accidents (41.79%) and blunt trauma (16.42%).
Implications:
- This case highlights a rare complication of head trauma and spinal injury.
- Early diagnosis and management are crucial for visual recovery.
- Further research into the mechanisms and treatment of traumatic internuclear ophthalmoplegia is warranted.

01:14Cranial Nerves: Types Part I
Cranial nerves are responsible for transmitting motor and sensory information between the brain and various parts of the body. There are twelve pairs of cranial nerves, with the first six being essential in sensory perception, motor control, and autonomic functions related to the head and neck.
Olfactory Nerve (Cranial Nerve I)
The olfactory nerve, or cranial nerve I, is unique as it is purely sensory and dedicated to the sense of smell. This nerve originates in the olfactory epithelium of the...

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...
