Hi there. I was very interested to read your post about DVLA and field test results etc. it so difficult to get info as everyone is unique. Hope you're doing well.
My 20yr old son is post TBI (11 months) from a terrible life-threatening car crash that fractured his skull and broke his neck. His brain has reacted amazingly, everyone is astounded by his recovery.
He recovered really quickly from all his injuries and is cognitive functioning to the same high standard as before and we are so very lucky to only have some sight impairment as a long lasting side effect from his life threatening injuries but with no problems in daily life and cycles to work each day!
We have Specsavers Esterman tests results. His left side scotoma blind spot is to the left of his central vision (he has normal central vision 20/20 acuity it exceeds 30 degrees) It is ONLY evident when he fixates ? Just short of the left 50 degrees peripheral for DVLA criteria a crescent shape cloudy section but he can see it.
They keep calling it a Homonymous hemianopsia but yet he has perfect central vision daily and on Esterman tests beyond 30 degrees, so his other Ophthalmologist calls is an occipital scotoma as when fixates forward that is ONLY when it is evident but he can see people/objects at his left at 9 and 10o’clock peripheral.
We spoke to DVLA and he can apply as an Exceptional Case at 12 months (September 2018) He has passed 5 out of the 6 DVLA field criteria for appeal and we are building up his ‘clinical adaptation and functions’ include evidence of safe working in his management job in a busy warehouse, cycling to work, GoKarting (pole position!) and we are applying for off-road driving assessment with RDAC end of August as proof his sight is working unless out in Esterman space helmet and made to stare/fixates for a while. (we understand completely DVLA may see this ‘stare/fixates’ could be apparent if looking to the right at interesting people or other cars!)
I would love to have your advice and am happy to give my email firstname.lastname@example.org
Thank in advance

'SHOULD HAVE GONE TO SPECSAVERS '
(A blind miracle or just a massive cover up!)
After being a passenger in a terrible car accident in 1995 age 22 which resulted in my left eye being removed i finally built up the courage in 2003 to learn to drive.
Although I had held a provisional driving licence for 13yrs and have never experienced any sight problems i decided to have a routine eye test performed in my remaining eye before I started learning to drive again.
My eye test showed that although I had perfect vision I had a profound field loss otherwise known as tunnel vision and although I was not aware of this I had to inform DVLA that I had been told by my optician that I was unfit to drive.
I was referred to hospital for further tests which showed entirely different results but unfortunately mistakes were made between specialists and my driving licence was revoked .
I have always maintained that my eyesight has been absolutely fine despite being told i had a profound field of vision loss!
The psychological impact that being told by a specialist that you are nearly completely blind one day and then told by another specialist month’s later your sight is fine was the worst and scariest feeling I have ever had.
With 2 contradicting diagnosis on my eyesight and after being sent to various specialists who could find nothing to explain any field loss I decided to fight for my licence and over the next 10 years despite letters from my GP supporting my application DVLA refused to give it back.
In 2013 My daughter complained she had trouble seeing the board at school, I panicked thinking she may have this mystery condition with her sight also and booked us both in for an eye test at my opticians.
The optician could find nothing wrong with my daughter's sight. My eye test showed to be perfect also and I questioned the optician as to why they had told me in 2003 that I had profound peripheral damage yet my eye sight was today better than normal .
The optician explained that the normal eye test wasn't as extensive and the peripheral damage would only show up on an esterman test. After a short discussion I was put forward to register as partially sighted and the optician sent off my field test results from 2003 to the hospital and GP .
The optometrist at hospital looked at the charts supplied by my optician and decided that my profound peripheral damage was so bad that I should be put forward for registration.
Yet again my heart fell into my stomach after being told that I had this vision loss that I was not aware of and I was sent for an electrical test or EEG . The results came back from the test and they couldn't find any explanation for the field loss but never the less i was registered partially sighted .
By this time I was so frustrated I can't explain the feelings I had .
After 10 frustrating years battling with DVLA to get my licence back trying to prove my eyesight was fine and being sent here, there and everywhere for further field tests from various machines i finally gave up and accepted defeat.
In 2015 I had another esterman test at my opticians and although i wasn't told the result I just carried on with my life planning my immanent blindness .
In October 2017 at my annual eye test I was told yet again that I had perfect vision and my peripheral vision was fine , my husband questioned this with the optician and was told yet again that although the periphery was good that it wasn't as extensive a test as the esterman field test , my husband requested we had a test on the esterman machine and the results were outstanding showing no field loss what so ever.
My husband Michael has recently completed training as an ocularist and we both now run our own clinic 'Lynch ocular prosthetics' in Lytham St Anne's manufacturing and fitting artificial eyes In association with John pacey Lowrie ltd.
During clinical training in ocularistry with renowned ocularist John Pacey Lowrie my husband has met many people who drive with only one eye and after extensively researching the internet found that errors with a machine used for field testing was found to be faulty between 2010 to 2015.
Confused and happy these findings I reluctantly reapplied for my provisional licence. I received a letter from DVLA 5 weeks later saying my charts weren't acceptable as they didn't meet the requirements. Luckily this time my husband had researched these machines and learned how to interpret the results so he was expecting this reply from DVLA and we booked into Specsavers opticians for a binocular driving field test .
I took the text which is strangely enough is for a person with 2 eyes . I passed the test with flying colours which means I have a field as good as if not better than a person with both eyes and meet the criteria for driving.
I also consulted with a specialist ophthalmologist who informed me that the machines used in 2003 was not a very reliable model and the results from that machine were unreliable as a diagnostic reference.
I explained that I had found information regarding faulty machines used before 2015 but the specialist told me there was nothing wrong with the machines software but that various machines were very difficult for some clients to operate and this was discovered by Specsavers in 2015 who resolved the problem by scrapping these machines and replacing them with better ones.
For this reason I believe there has been a massive cover up and the implications of owning up to this would open the flood gates to DVLA . This is why no one can get to the bottom of the mystery of the machines.
Before Specsavers took over the contract for DVLA it was covered by various independent opticians who all had different machines producing different results which made it very difficult for DVLA to interpret the information presented and has resulted in people losing their driving licence.
By using the same easy to follow model of machine across the board Specsavers resolved the problem .
The staff in Specsavers are extremely competent and polite and the optician was informative and professional explaining the test and results .
I officially have perfect vision and although it has been very traumatic and frustrating over the past 14yrs I have no regrets because the circumstances have ultimately led to my husband and I to be working together in a job which we both feel extremely passionate about .
When you only have one eye and being told you have defects in that eye is devastating so it is paramount that you get second opinions and the best care.
I would certainty recommend booking into Specsavers if you have any doubt about eyesight and driving.
I have performed 4 field of vision test in 4 months since re-applying for my driving license in October 2017 and have also submitted a statement from a specialist ophthalmologist confirming that results from my initial tests in 2003 were classically unreliable as a diagnostic reference. I have also been taken off the partially sighted register after showing all my evidence to my GP.
DVLA are almost impossible to deal with when applying or following up any queries regarding your driving licence and you cannot speak to any medical advisors but only telephone operator's .
