Summary
A stroke caused sudden vision loss and double vision due to left carotid artery thrombus. This led to ophthalmic artery occlusion and oculomotor nerve palsy.
Area of Science:
- Neurology
- Vascular Neurology
- Ophthalmology
Background:
- A 54-year-year-old male with a history of stroke, epilepsy, and substance abuse presented with acute visual symptoms.
- Risk factors included tobacco and marijuana smoking, and alcohol abuse.
Observation:
- The patient experienced acute left visual loss and diplopia.
- Examination revealed reduced left visual acuity and left oculomotor nerve palsy.
Findings:
- CT angiography showed extensive thrombus occluding the left common and internal carotid arteries, extending to the left ophthalmic artery.
- This resulted in ophthalmic artery occlusion causing visual loss.
- Occlusion of the inferolateral trunk of the internal carotid artery led to oculomotor nerve palsy.
Implications:
- This case highlights acute visual loss as a symptom of ophthalmic artery occlusion.
- It also demonstrates oculomotor nerve palsy secondary to internal carotid artery occlusion.
- The findings underscore the importance of vascular imaging in patients with acute visual disturbances and neurological deficits.

02:00Internal Energy
36.7K
The total of all possible kinds of energy present in a substance is called the internal energy (U), sometimes symbolized as E. Suppose a system with initial internal energy, Uinitial, undergoes a change in energy (transfer of work or heat), and the final internal energy of the system is Ufinal. Change in internal energy equals the difference between Ufinal and Uinitial.

01:29Internal Energy

The internal energy of a thermodynamic system is the sum of the kinetic and potential energies of all the molecules or entities in the system. The kinetic energy of an individual molecule includes contributions due to its rotation and vibration, as well as its translational energy. The potential energy is associated only with the interactions between one molecule and the other molecules of the system. Neither the system's location nor its motion is of any consequence as far as the internal...

Many cellular signals are hydrophilic and therefore cannot pass through the plasma membrane. However, small or hydrophobic signaling molecules can cross the hydrophobic core of the plasma membrane and bind to internal, or intracellular, receptors that reside within the cell. Many mammalian steroid hormones use this mechanism of cell signaling, as does nitric oxide (NO) gas.

4.0K
The cranial and spinal meninges are complex protective structures surrounding the central nervous system (CNS), consisting of the brain and spinal cord. These meninges consist of the dura mater, the arachnoid mater, and the pia mater. They protect the CNS, provide structural support, and aid in circulating cerebrospinal fluid (CSF).
Cranial Meninges
These meningeal layers cover the cranium. The dura mater is the outermost layer of cranial meninges. It is a thick and durable membrane of dense...

5.2K
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...

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. While the first six innervate the head and neck, the latter six nerves innervate the head and neck, as well as organs and tissues in the thoracic and abdominal cavities. They facilitate communication, expression, and autonomic control within the human body.
