I wrote a long first post and at the end I mentioned that I'd been tested by a behavioural optometrist. I had the glasses last Saturday but have waited till now after using them to let everyone know how it went. Remember I had a hard hit to the back of the head, had a negative CT scan, diagnosed with concussion. My first post has a lot more detail of the symptoms I experienced if you want to cross reference with your own.
The report from the optometrist (who stressed that ABI was not her speciality) mentioned visual stress, photophobia, distortion of the visual field, pattern glare and visual disturbance was found and the cause is cortical hyperexcitability. (This is a general term and covers everything from migraine to parkinson's. She said you need to be tested by a specialist in ABI.)
Anyway, I put the glasses on and my vision settled immediately, everything stopped moving and the brightness reduced. After a few minutes I got a sharp pain through my right eye. I had to get used to the prescription and deep blue colour lenses, I felt out of sorts.
I went for a walk in the bright sun, had no issues at all, I could focus and see everything. It's an overwhelming feeling, a bit of normal. I walked for about 2 hours and began to feel that I was becoming aware of my surroundings in a dynamic 3D way, my hearing became directional rather than central and the sounds separate not coming in all together. I just crossed a road, I did'nt stop and look again and again and make a decision to cross, I just looked back and fore and gauged the elements of the scene and crossed before knowing it. My memory and concentration began working in unison with my vision and hearing.
This is in the first few hours, I had energy, I did'nt know what to do with it, it's an odd feeling. That night I closed my eyes and there were no flashing lights, yellow clouds or spiralling coloured globes just a dark black blue. I slept deep and well. Here's the next brilliant thing I've had tight muscle grip from my right eye across the whole side of my head and into my neck, and an area from my cheek through the ear area to the neck on the left side. This was gone when I woke up.
I looked about next morning, without my glasses and the patterns were moving as usual, the outside light was too bright, words scattered across the computer screen. I put the glasses on and it all stopped immediately. Since then energy levels have increased, the visual, hearing, memory and concentration have tightened become more cohesive.
The glasses don't work in fluorescent light, it's even worse.
I still have glitches where I forget what I'm talking about, but reduced to only 2 in 3 days, where the norm is aprox half a dozen per day.
My speech still slurs.
Future organising is as bad as before.
Today I began joking and teasing and was absorbed in a conversation and not separated from it trying to keep up, dealing with each sentence separately not seeing a bigger picture like before. I have had no daytime sleeps at all since the glasses, I have no fatigue any more (touching wood).
I still get a few moments where everything stops but I'm aware of my surroundings and not just blank for that period of time.
I am astonished by all this.
I did this as an experiment after reading about how the visual system is key to most functions in the brain. Other people have done this too, it's common in the US, and depending on the damage a person has after an accident or illness will depend on how the visual system affects it. Most of my symptoms seem to be improving a lot and some have had no improvement at all.
My injuries are minor in comparison to most other people on this site and are mainly visual in nature. I think anyone with a visual element could find some kind of improvement via this method.
The person who tested me, I found her independently, is a member of BABO, British association of Behavioural Optometrists. (I think I'm ok in mentioning this). This is private testing, I thought it was cheap.
I spoke to a member of Headway staff on the phone before the testing was done and was asked to report back the findings as this process in not commonly used in the UK.
Get informed if you think it may help.
