Introduction to superior orbital fissure syndrome

Superior orbital fissure syndrome is an eye disease. Eyes are the windows to the human soul. If there are some problems with them, they should be given more attention. If we lose our eyes, we lose our light, our colors, and so many beautiful things. Therefore, we need to know more about eye diseases. Superior orbital fissure syndrome is one of them. Let us learn about it together.

The superior orbital fissure is located on the outside of the optic nerve in the orbit, at the junction of the superior and lateral orbital walls, and is composed of the greater and lesser wings of the sphenoid bone. This connects the middle cranial fossa to the orbit. The posterior end of the superior orbital fissure merges with the inferior orbital fissure. The III, IV, VI cranial nerves, the ophthalmic branch of the V cranial nerve, the superior ophthalmic vein, the orbital branch of the middle meningeal artery, and the sympathetic nerves pass through this fissure. If there is a lesion in the orbit or orbit that involves the superior orbital fissure, superior orbital fissure syndrome may occur. The oculomotor, trochlear and abducens nerves on the same side of the lesion are paralyzed, resulting in complete ophthalmoplegia, manifested as ptosis, fixed eyeballs, various movement disorders, mydriasis, and loss of response to light and accommodation.

The cause is still not fully understood. But there are various reasons as follows.

(1) Non-specific orbital inflammation affects the superior orbital fissure or inflammatory granulomatous tissue compresses the superior orbital fissure. Orbital soft tissue inflammation secondary to extraocular muscle surgery or paranasal sinusitis may spread to the superior orbital fissure meninges and cavernous sinuses, and central nervous system infection may spread to the superior orbital fissure.

(2) Intraocular or intracranial tumors involving the superior orbital fissure, such as uncus tumors.

(3) Traumatic zygomatic bone fracture, edema, and hemorrhage compress the superior orbital fissure.

The following preventive treatment measures need to be kept in mind:

1. Avoid excessive visual fatigue. You should use your eyes in moderation without feeling tired, and pay attention to correct eye posture, distance, and whether the light source is sufficient. After using your eyes for about an hour, let your eyes relax for a while, such as closing your eyes, walking around, looking at the sky or into the distance, etc., so that your eyes can get a rest. Try not to read or work in dim environments for long periods of time.

2. Avoid excessive emotional excitement, keep a good mood, ensure smooth circulation of qi and blood throughout the body, and improve the body's resistance to disease.

Eye diseases, in addition to being caused by external injuries, are basically caused by not getting better protection in daily life. In life, as long as we are not suffering from insomnia, we need to use our eyes. Therefore, we need to learn more about how to give our eyes enough rest and how to protect our eyes. Once we feel eye discomfort, we should seek medical attention in time. Protecting our eyes is to protect the windows of our soul.
