Wade, a Concept Eye Clinic offer The Noctura 400 Sleep Mask from PolyPhotonix. The Noctura is a revolutionary treatment for diabetic retinopathy and diabetic macular oedema (DMO). 

Diabetes and the eye 


  • When you have diabetes, high blood glucose levels and circulation problems can cause changes to the blood vessels in the eyes and lead to diabetic retinopathy

  • When it is dark and you are asleep, the eyes need more oxygen

  • In the diabetic eye the retina can become starved of oxygen

  • The eye tries to produce new blood vessels to deliver more oxygen to the retina

  • These new blood vessels are often weak, leak fluid and blood, which affects vision and could lead to total sight loss if left untreated

The Noctura 400

The Noctura 400 Sleep Mask is an innovative technology, which can be used as a therapy for diabetic retinopathy and diabetic macular oedema. The mask administers a precise low-level light through closed eyelids while you sleep, to reduce oxygen demand

Treatment Program

The treatment is part of an ongoing monitored therapy and regular check-ups are provided.

At the end of a 12 week period, the mask is returned for analysis and a replacement mask is provided. The collected usage data allows the clinician to compare the patient's usage of the mask with changes in vision.
