What's the difference between strabismus & cranial nerve palsies that effect the eyes? Can cranial nerve palsies cause strabismus?

What's the difference between strabismus & cranial nerve palsies that effect the eyes? Can cranial nerve palsies cause strabismus?

Different patterns: Strabismus is the generic term for eye misalignment of any cause. If from childhood, the eyes are separated about the same in all positions. If from cranial palsy, the degree of separation goes from normal away from the action of the muscles, to a very wide difference in the direction of the action of that muscle. An ophthalmologist can usually readily make this distinction. ...Read more

Palsy (Definition)

...is a corruption of French "paralise" from Latinized Greek "paralysis." In the old days it meant any kind of persistent weakness. To this day Parkinson's disease is also called "paralysis agitans" which is a Latin translation of Dr. Parkinson's original name for it, the "shaking palsy." We've obviously reborrowed the full form "paralysis" into English as well; today ...Read more

"microsurgical reconstruction of the infraorbital nerves". Mozsary pg, middleton ra. Damaged nerve. 6 cases of full reocver in 7 patients. Possible ?!

"microsurgical reconstruction of the infraorbital nerves". Mozsary pg, middleton ra. Damaged nerve. 6 cases of full reocver in 7 patients. Possible ?!

Nerve Reconstruction: It depends on what the cause of the original nerve damage was. Ophthalmologists can do wonders these days, so i would certainly suggest making an appointment and get an opinion. The authors report on successful reconstruction in cases where the nerve was intact, but trapped by scar tissue. Your case may or may not be similar, so it is best to undergo a complete evaluation. ...Read more

Each peripheral nerve provides what innervation to peripheral structures.?

Each peripheral nerve provides what innervation to peripheral structures.?

Good question: I wish I could remember. When I have a question about that, I get out my old anatomy book from med school and look it up. The book is 1100 pages long. I refer to it frequently when I want to relearn what peripheral nerve innervates what structure. For laypeople I recommend Frank Netter's Atlas of Human Anatomy. It's available from Amazon. ...Read more

Optic nerve crushed, optic nerve transplant?

No recourse: A crushed optic nerve (how did this happen to you?) causes permanent changes which will alter the vision sometimes severely. There is currently no treatment known for this and a transplant is not possible. A discussion with a neuro-ophthalmologist would be helpful in this situation. ...Read more

How is third nerve palsy diagnosed?

How is third nerve palsy diagnosed?

History and exam: Typically the diagnosis of a third nerve palsy is made by a history of double vision and then a clinical exam that demonstrates and abnormality of the opening of the eyelid (ptosis), the pupillary size (bigger) and/or the eye movement. Imaging may be useful for uncovering the cause, but the diagnosis is made clinically. ...Read more

Nerve (Definition)

The brain and spinal cord communicates with what is occurring in the internal organs and limbs by nerve fibers where are like electrical wires with insulation (myelin) and the "copper" (axon). Within brain and spinal cord these nerves connect to other nerves via synapses on both axons and dendrites. A nerve can carry information regarding sensations, and ...Read more
