Abstract:
Here, we report a rare case of bilateral medial rectus palsy following closed head injury. An adult male had an accidental fall which rendered him unconscious. This was followed by diplopia and restricted ocular motility. He received supportive medical therapy. He was examined for systemic medical and ophthalmic findings. Routine laboratory tests and imaging techniques were employed as per the symptoms. Diffusion-weighted imaging on magnetic resonance imaging proved it to be a rare presentation of small bilateral midbrain infarct. He recovered fully after 8 months.

Muscles that Move the Head
The bilateral sternocleidomastoid, or SCM, and the suprahyoid and infrahyoid muscles are significant head flexors. The SCM muscles originate at the sternum and clavicle and attach to the mastoid process of the temporal bone. The SCM contracts bilaterally to bend the head forward, whereas...

Veins of Head and Neck
On the other hand, the vertebral veins, unlike their arterial counterparts, are not primarily responsible for brain drainage. Instead, they drain the cervical vertebrae, spinal cord, and some small...
Burn Injuries
The damage results in the death of skin cells, which can lead to a massive loss of fluid. Dehydration, electrolyte imbalance, and renal and circulatory failure follow, which can be fatal. Burn patients are treated with intravenous fluids to offset...
