Eye expert on leading causes of irreversible sight loss in warning to Portsmouth residents

Age-related macular degeneration (AMD) is one of the leading causes of irreversible sight loss in Portsmouth, particularly among people aged 55 and over.

Yet despite its prevalence, many people remain unaware of what AMD is, how quickly it can progress, or the early warning signs to look out for.

To mark AMD Awareness Month this February, Optical Express is encouraging people to prioritise regular eye examinations and to take gradual changes in vision seriously, rather than dismissing them as a normal part of ageing.

Dr Stephen Hannan, Clinical Services Director at Optical Express, explains that AMD often develops gradually, which means changes can go unnoticed in the early stages. Symptoms may include blurred or darkened areas in the centre of vision, straight lines appearing distorted, difficulty seeing fine details, and colours appearing less vivid.

He said: “AMD affects the macula, which is the central part of the retina responsible for sharp, detailed vision and colour perception. When the macula starts to deteriorate, small yellow deposits known as drusen form beneath the retina. This means it can become increasingly difficult to see clearly straight ahead, making everyday activities such as reading, driving or recognising faces more challenging over time.

“Because there’s no pain or dramatic vision loss, many people don’t realise they’re experiencing AMD until it progresses to the later stages and starts to interfere with daily life.

“As AMD advances, damage to the macula becomes more pronounced and can’t be restored, which is why routine eye examinations are so crucial in identifying minor changes before significant vision loss occurs.”

AMD has had a life-changing impact on more than 700,000 people in the UK¹, including Dame Judi Dench, who has spoken openly about how the condition has affected her ability to recognise faces, watch TV and read.

A number of clinical and lifestyle factors are known to influence the development and progression of AMD. Smoking remains the most significant modifiable risk factor, while research also shows that poor diet and prolonged UV exposure can negatively affect retinal health.

Addressing these risks, alongside routine eye examinations, plays an important role in protecting long-term vision and preventing significant sight loss. Optical Express is encouraging people, particularly those aged 55 and over, to use AMD Awareness Month as a reminder to prioritise their eye health and seek professional advice if they notice any changes to their vision.

Dr Hannan added: “Not all AMD progresses in the same way, but early detection allows us to monitor changes closely and, in some cases, begin treatment that can help preserve remaining vision. It’s important people understand that sight loss from AMD isn’t an inevitable part of ageing – it’s a medical condition that needs proper assessment and ongoing care.

“Routine eye examinations allow us to detect early changes in the eye, often before patients are aware of symptoms. The earlier we can identify AMD, the better our chances of slowing its progression, making a significant difference to long-term visual outcomes.”
