I beg to move,
That leave be given to bring in a Bill to make provision about the detection, treatment and monitoring of glaucoma by optometrists in England; to make provision about the full integration of optometry and ophthalmology services for the purpose of glaucoma care in England; and for connected purposes.
I refer hon. Members to my entry in the Register of Members’ Financial Interests; I am a practising NHS optometrist. I also thank the Minister for Care for coming to the Chamber for this valuable debate.
As a practising optometrist of many years, one of the heartaches of the role is this: during a routine examination, I can detect a condition that will forever change the life of the person who is sitting in my chair, and the patient is blissfully unaware of it. That is exactly what glaucoma does—it changes lives quietly, and often without warning. Glaucoma is known as the thief of sight, and for a very good reason. It damages the optic nerve at the back of the eye, with each nerve fibre representing a different point in the visual field. Because the loss begins in the peripheral vision, people often do not realise that anything is wrong until it is too late.
If Members would like a glimpse of what an advanced glaucoma sufferer sees, may I ask them to cover one eye completely and, with the other eye, to look through an aperture created by their hands and touch their fingertips to their palms? As the condition progresses, the aperture gets smaller and smaller and smaller, until eventually nothing is left. Imagine trying to navigate a busy high street, to cross a road or simply to move safely around one’s own home.
This is not simply theoretical; let me give the House two brief but very real examples from my experience. I saw a woman who on two separate occasions was hit by a car from the side while driving her own car, before she finally came in for an eye test. She was unaware that there was a problem, because she could see number plates and road signs perfectly. What she could not see was the side of her vision eroding.
Another heartbreaking experience when a pensioner came to me with a handbag packed with what looked like her life savings. Cash in hand, she explained that she would spend whatever it took if I could just give her a pair of glasses that would allow her to see her two loves: her love of painting and her grandchildren. Unfortunately, no amount of money would be able to restore her sight, because glaucoma, as well as being silent, is usually irreversible.
Glaucoma is the leading cause of preventable blindness in the UK. Over 700,000 people are affected by it, and, even more concerningly, more than half of them are undiagnosed. That is 350,000 people walking and driving around, not knowing. It could be any one of us, or someone we love or work with. Indeed, a former Liberal Democrat Member of this House, Paul Tyler, was not diagnosed until a routine eye test.
