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, leading to permanent scarring of the retina.

How does the Noctura 400 work?

The Noctura 400 works on a very simple basis. It is a face mask that you wear while you sleep, containing low powered LED lights, providing low levels of illumination to your closed eye lids. The lighting is low enough to avoid affecting sleep, but provides enough light to prevent the rod cells in your eye from activating.

‘Rod’ cells are light receptive cells in the retina that, along with ‘cone’ cells detect light and provide the information to the brain required to form an image. Cone cells detect colour and detail in good lighting, while rod cells are used in low light. There are twenty times more rod cells in your eye than cones and they activate in any low light, even when your eyes are closed at night.

This large number of active cells means that the eye has a high oxygen demand at night and in the diabetic eye, this can increase the risk of retinopathy. When the Noctura 400 stops these cells from activating at night, it reduces the oxygen demand and the risk of the eye forming extra blood vessels.

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.
