As we get older our senses start to deteriorate, so how do we keep our senses sharp as we age, and how can we slow down the effects of age-related vision loss? Let us look at one condition, in particular, glaucoma.
Glaucoma is a leading cause of irreversible blindness, affecting millions worldwide by damaging the optic nerve, mostly due to elevated intraocular pressure (IOP). It is also known as the “silent thief of sight” as many people may lose up to 80 to 90% of their peripheral vision before it is detected.
Recent advancements in technology are shining a light of hope for patients grappling with this condition. A study conducted in Switzerland by Professor Kaweh Mansouri, who has been recognised as one of the most influential ophthalmologists worldwide, set out to determine the effects of exercise on glaucoma. A groundbreaking smart contact lens was used specifically for continuous monitoring of intraocular pressure over time.
This innovative lens has advanced sensors that provide real-time data, allowing patients and healthcare providers to track eye pressure fluctuations effortlessly. Professor Mansouri fitted a volunteer, a 75-year-old woman named Doris, who had previously been diagnosed with glaucoma, with this soft high-tech contact lens. The contact lens monitored her eye pressures continuously for 24 hours.
Pressures were captured throughout her day, and while she performed various activities such as spinning, cooking, and gardening. The results obtained were astonishing. At around 4pm, Professor Mansouri noted a significant decrease in Doris’s intraocular pressure. This was the exact time of her hour-long spinning class every afternoon.
Other studies have shown that physical activity does decrease intraocular pressure, especially aerobic activities such as swimming and cycling. Research has shown that even walking an extra 5000 steps a day can reduce glaucoma-related sight loss by as much as 10%. Professor Mansouri was amazed by the results and has advised that leading a healthy active lifestyle with daily exercise should be a vital component of the management and care of glaucoma patients. Doris goes for regular check-ups with the ophthalmologist and her results show that her glaucoma has remained stable.
Continuing to refine this technology and making significant discoveries, such as the positive effects of exercise on age-related sight loss, represent important advancements in glaucoma care. For patients, this signifies a future where managing their eye health is more effective and less burdensome.
