Sir,
We read with interest the comments of Dr de Jong and his colleague on 'Visual field defects in adults secondary to preterm delivery'.
I can confirm that Case 1 had both a central 24/2 Humphrey visual field and the standard DVLA binocular Esterman visual field test. As you mention, Case 1 passed her driving test without being aware of any field defect. With regard to Case 2, I am unable to trace any disc photographs. I was in touch with the DVLA and their ophthalmological advisers regarding Case 1 and can report that her driving licence was returned to her approximately 6 months ago, after a great deal of negotiation.
We hope that the recent modifications in field standards proposed by the DVLA, dated 7.7.02, will reduce the risk of peremptory loss of licence and livelihood in the future.
