Oct shows nerve tissue thinning. No visual field loss. 1 dr. Said 30% optic nerve damage & 2 others say not that much. Can percentage be relied on?
Need to follow: Patients can lose nerve fiber layer before it produces visual field or visual acuity is affected. You need to be followed over time looking at all parameters: visual acuity, intraocular pressure, nerve appearance, oct and visual field an past medical history.

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
Diagnosed w/glaucoma. Opthomologist said no peripheral vision loss. No optic nerve damage but the nerve tissue has thinned. How serious is that?
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?
I would definitely recommend close follow-up with a physician to do careful examination of your eyes and head/neck. ...Read more

? optic neuritis: The description is partial, but sounds like you may have optic neuritis, and pain occurs when one moves the eye. This absolutely needs to be treated with steroids, which will speed recovery. Hopefully, you are in contact with a good ophthalmologist, but you may well need neurological consultation, as, in many cases, this is the first sign of a chronic neurological disorder. ...Read more
VER: A very nice test can be done to measure the optic nerve conduction velocity. This is the visual evoked response or ver. A p100 can be measured that can be compared with the normal range for the laboratory where the testing is done. Delays in conduction can be seen in a variety of disorders, most common with the diagnosis of multiple sclerosis. ...Read more
No: Cholesterol is part of normal metabolism-your body actually makes the stuff. We are concerned about blood levels due to deposition in vascular lining. The optic nerve does have a blood supply and might have some changes similar to cholesterol elsewhere in the body. How did you discover cholesterol on your optic nerve? Recheck with your ophthalmologist and see if you heard this properly? ...Read more

Go back to your doc: Unfortunately, I have never heard the term of metabolic waste on an optic nerve. I think that's why it's taking so long to get an answer. I think you may have an optic nerve condition and the ophthalmologist tried to explain it to you in layman terms and the description was misunderstood somehow. I suggest you go back to the ophthalmologist and have him/ her explain it again. Sorry not good help. ...Read more
