From A. Wills, London, UK
You report uncertainty over the UK's supply of medicines in the event of a no-deal Brexit (19 January, p 5). A family member has glaucoma and uses prescribed eye drops to control it. Without drops, eye pressure rises and puts pressure on the optic nerve. Permanent blindness can result.
Is the UK Department of Health stocking up on glaucoma drops? Apart from the tragic personal cost of those who would go blind, it would be expensive to take care of the needs of the many people who could lose their sight, and who are now able to work, drive and run their homes without needing other help from the authorities.
