HGV medical and glaucoma!

Glaucoma is a condition in which the pressure inside the eyeballs becomes raised. The reason why glaucoma matters is that it very, very slowly causes a person to lose their peripheral vision and because it happened so slowly people often don’t notice that they are gradually losing the edges of their vision.
So it’s obviously very important for DVLA to know about this. They are not so much worried about the diagnosis of glaucoma, but what worries them is the loss of peripheral vision. You wouldn’t be likely to lose your licence just because of having glaucoma (although you don’t know you have it at the moment anyway), but you could lose your licence if your visual field is impaired.
The rules are quite complicated but you can read them yourself in the DVLA publication “Assessing fitness to drive - A guide for medical professionals”. You can easily find this if you Google the name. You need to go to pages 88-89 of the current version (May 2016) which explains all about the precise visual field requirements and how many individual dots you are allowed to miss on the test.
Did the optician say whether you met the DVLA group 2 standard or whether you failed it? If she said you don’t meet the DVLA group 2 (HGV) standard on the visual field test then you should stop driving lorries until DVLA make their decision. If she said that you haven’t failed the standard then you can relax, and if DVLA agree with the optician then there’s no reason why they should take away your licence for the visual fields.
They may send you for another more detailed visual field test before they decide.
Hope this helps.
