If you drive and you have been diagnosed with glaucoma in both eyes, then this will reduce your field of vision. It is not just about what your visual acuity is. i.e. The lowest line on the chart you can read when corrected with a spectacle prescription. The issue is how far to the right/left up and down can you see when looking straight ahead. This is called your visual field. The law says that you must tell the DVLA (Driver and Vehicle Licensing Authority). The DVLA may require you to take another Visual Field test which satisfies their specific fitness to drive criteria tests. Many people are given an extended licence to allow them to continue to drive for a further period before being recalled to be monitored again.
Some people have to have their driving licence revoked because they could become a danger to themselves and others. In our experience, many patients initially resent this and are in denial of the reality of the facts. They soon accept a change in lifestyle and recognise that taxis and public transport works out less than running a car and often family and friends will support them where they can.
