Unfortunately yes: Retinal detachment often disrupts the supply of blood to the retina. This can result in loss of pressure control, glaucoma and optic nerve damage. Rd surgery often involves a vitrectomy, removal of the vitreous humor from the eye. Optic nerve damage can result from such surgery. Caught and appropriately treated early, rd should not result in damage to the optic nerve. ...Read more
No repair: Unfortunately, vision loss due to damage to the optic nerve from glaucoma is not considered reversible. This is part of the reason that screening for glaucoma is an important public health issue -- treatment to prevent or decrease progression is well established, but there is not treatment to reverse vision loss from glaucoma. ...Read moreSee 3 more doctor answers
Can the ilioinguinal nerve and genital branch of genitofemoral nerve be evaluated by MRI for any problems?
Here are some...: Why do you raise this Q? Any concern after a surgery should be evaluated with detailed history to specify the features of symptoms with clear sequence of events + properly physical exam so to define what you felt & concerned after surgery is related with surgery itself or just lingering effect of healing process.

Yes: Optic nerve can be seen on ct, especially with contrast. Depending on the space between the imaging sections, one may see only part of the optic nerve. Mri can be a better imaging study of the nerve, which is soft tissue. Ct is better for examining bony structures. ...Read moreSee 2 more doctor answers

Spinal cord: The spinal cord is a long, thin, tubular bundle of nervous tissue and support cells that extends from the brain down to the space between the first and second lumbar vertebrae. Nerves branch off the SC that innervate other body regions/parts. Depending on the extent of the injury and the time frame at which the injury is tended to will depend on the ability for the area to heal, if at all. ...Read more

Report visual fields: If the chiasm was affected then, you'd have lost visual fields in BOTH eyes. If you had visual field loss only in one eye then, it is more likely that the problem is in front of or beyond the chiasm which could be then, an optic nerve or one set of optic radiations. ...Read more
If during surgery a wrong nerve, say the ilioinguinal nerve is excised by mistake, can the surgeon perform microsurgery and connect the nerve again?
Different items: Papilledema is a sign of increased intracranial pressure of any etiology, and can be due to tumor, hydrocephalus, brain hemorrhage, infections. Swelling of the optic nerve can be due to optic neuritis or other inflammatory problems. Spinal fluid leaks can be due to trauma over skull such as cribiform plate fracture.

Visual cable: The optic nerve, the head of which is described in the back of the eye by your ophthalmologist as the disc, is the cable carrying visual information into the brain where it ends up in the occipital lobe and interpreted as vision. It contains over 1.2 million fibers as well as supporting elements.A truly amazing nerve. ...Read moreSee 3 more doctor answers

If there is a sudden change in the vision, which is a hallmark of optic nerve dysfunction, see your ophthalmologist right away. ...Read more
Tilted: Most optic nerves enter the eye straight on, like a cable pushed into a styrofoam ball perpendicular to the surface. In some eyes, the optic nerve enters at an angle, leading to a tilted appearance. This occurs most commonly in nearsighted people (myopes). ...Read moreSee 2 more doctor answers
Possible glaucoma: You would not know about this unless your eye was evaluated by a doctor .. Optic nerve thinning, also termed cupping, can be due to elevated pressure inside the eye which is termed glaucoma. I assume the doctor who discovered this was an ophthalmologist (I hope) who would initiate a work up to see if this is the cause. You should be seeing, for this, an ophthalmologist. ...Read more
Nonspecific: Hi! Lots of things to consider; what symptoms prompted you to get the scan? Any change in vision? Sinus pain or congestion? Bone pain elsewhere in your body? Headaches? Fever?
