Electrode test eyes, help needed

[TearsForFears24]

Shameless posting for traffic as in a tailspin. Long story short, I went for a routine eye test/scan a couple of months ago. The scan observed a thin optic nerve and I missed spots in the visual field exam. No pattern to the spots I missed. Was referred by the optician to the glaucoma clinic. Repeated the visual field last week and saw the consultant today who done another scan. He said I was still missing spots on the visual field, and the scan showed a change in the colour of the optic disc. Apparently it should be pink but mine has parts where it is yellow. He didn't seem massively concerned and stated it's not gluacoma but is referring me to a different clinic where they use electrodes to test the optic nerve. He wasn't very forthcoming about potential diagnoses but said it wasn't anything to worry about. When asked what could cause changes to the nerve he kind of shrugged and said something about excess alcohol, head injury, drug use etc. None of which apply to me.
I'm utterly terrified and sick to my stomach about the possibility of progressive vision loss. Unsure how he is confident it's "nothing serious" when there's clearly something going on. It's basically a love long phobia of mine to go blind so I'm really in a tizz. If anyone who has been in a similar situation could share their story that would be greatly appreciated. Or if there's any optometrists/opthalmologists that could advise?

Hopeful bump

I've had those tests done. In my case my consultant (and everyone else seen since 2009) can see something wrong but no one can decide what.

The electrode tests are uncomfortable but not painful.

Thank you so much for the reply @TigerRag. Did they mention anything about your optic nerves or what could be the possible causes of abnormalities? Do you have any vision issues?

I have a condition called Nystagmus which means my eyes shake. I was told at 19 (I was born with it) that it was optic atrophy.

They now think there's a neurological cause

This is a fairly comprehensive list:

Conditions that can be mistaken for glaucoma include compressive or infiltrative lesions of the optic nerve, previous ischemic optic neuropathy (both arteritic and non-arteritic), congenital and hereditary optic neuropathies, post-traumatic optic neuropathy and inflammatory and demyelinating optic neuritis. Most cases in the compressive category—intracranial mass lesions that cause optic nerve or chiasmal compression—will be pituitary adenomas, craniopharyngiomas, suprasellar aneurysms or meningiomas.

So, it's quite a big list! Which is why the consultant was being non-committal, it might be something, but equally might not be. They're doing exactly the right thing. Hope you get some answers soon.

Thank you for the reply @underneaththeash . Is it possible that this is an incidental find and it is my physiological baseline? Most of the things in that list seem quite scary! My biggest fear is that it's something that can't be treated

Absolutely!
Now that our testing equipment has become a lot more advanced, we pick up stuff that wasn’t noticed previously.

@TearsForFears24 I am in an eye tailspin as well. What was the outcome for you? Hope you are ok xx

Hey @PurpleJam2234, I've sent you a pm
