The Noctura 400 Tackles Diabetic Retinopathy While You Sleep

What is Diabetic Retinopathy?

Diabetic Retinopathy affects the majority of diabetics. Within twenty years of diabetes diagnosis, almost all Type I sufferers and two-thirds of Type II will develop retinopathy in some form. It is responsible for around 1,200 new cases of registered blindness each year in the UK.

Elevated blood glucose levels, caused by diabetes, can weaken and thicken the walls of blood vessels. This is particularly damaging in the tiny blood vessels at the back of the eye and it can reduce the amount of blood able to reach the eye as well as leading to swelling and leakage of blood or fluid into the eye. This is known as non-proliferative diabetic retinopathy. The damaged vessels cause damage to the vision, particularly if swelling occurs near to the macular – the centre of detail vision in the eye – a condition known as macular oedema. 

The eye requires a lot of oxygen to work, so if blood vessels are not providing the required flow, the eye will attempt to create new blood vessels to increase the blood flow to the retina – this is known as proliferative diabetic retinopathy. These new blood vessels are usually very fragile and prone to haemorrhaging, which can block vision and may require laser treatment or surgery to resolve.

How does the Noctura 400 work?

The highest demand that the eye has for oxygen is at night. The eye contains millions of light sensitive cells known as cones and rods that provide the information that makes up your vision. Cones are active during the day, they can detect high levels of detail and colours, rods are used in low lighting conditions and are very sensitive to light, but not to colours, which is why colours can be hard to make out in the dark.

There are twenty times more rod cells in your eye than cones, so when these are active they require a lot more oxygen. When you sleep the rod cells stay active, even when your eyes are closed, so this high demand for oxygen remains throughout the night. In a healthy eye, this is not a risk, but in an eye affected by diabetes this high oxygen requirement can lead to retinopathy.

The Noctura 400 works on a very simple basis. It is a face mask that you wear while you sleep, that provides low levels of light to your closed eye lids. Although it is not enough to affect your sleep, it is enough light to prevent the rods in your eye from activating and so it reduces the eye’s oxygen demands.

Is the Noctura 400 safe and effective?

The Noctura 400 is a brand new development in eye health, based on initial studies into the theory from 2010. It has undergone independent clinical trials and large scale trials are now ongoing.

Noctura 400 has demonstrated clinical repair in 66% of patients and caused no associated complications. After only 3 months of treatment these patients showed a measurable reduction in retinal thickness and a decrease in blood vessel permeability and leakage. It has proven effective in patients with very mild to severe cases of retinopathy.

The safety of the physical product is confirmed by the CE marking, verifying that its construction and electrics meet all European safety requirements. The light used by the device is pale green in colour and has been found to have no affect on sleep patterns.

How do I get the Noctura 400?

The Noctura 400 is provided as part of an ongoing monitoring program for your eyes. After your initial consultation which includes an OCT 3D Eye Scan, you will receive a mask which you wear for three months. We then carry out a follow-up examination of your eyes, including a further scan every three months. The scans allow us to precisely monitor the health of your eye and the extent of your retinopathy.
