Brief Summary:

In this study, the investigators aim to use light masks (Noctura 400) to test the hypothesis that preventing the dark adaptation and associated hypoxia of the rods in the eye could in turn prevent or halt the progression of centre-involving Diabetic Macular Oedema (DMO). DMO is a devastating disease that is the most common cause of registerable blindness in the working age-group in the United Kingdom (UK)

This is a multi-centred randomised controlled trial involving 240 patients. Post randomization, participants in the intervention arm will wear the Noctura 400 Light Mask at night for 48 weeks in conjunction with their routine, prescribed treatment of intravitreal (eye) ranibizumab. Those in the standard arm will receive their routine, prescribed ranibizumab treatment only.

The primary objective is to determine whether utilizing the Noctura 400 Light Mask at night reduces the number of intravitreal injections of ranibizumab required by patients undergoing such a course for the treatment of DMO.

Primary Outcome Measures :
  1. The number of intravitreal injections of ranibizumab required by each study eye at 48 weeks [ Time Frame: 48 Weeks ]

Secondary Outcome Measures :
  1. Mean difference from baseline Central sub-field thickness at 48 Weeks [ Time Frame: 48 Weeks ]
  2. Mean difference from baseline visual acuity at 48 weeks. [ Time Frame: 48 Weeks ]
  3. Mean difference in utility (quality of life). [ Time Frame: Baseline, 12 and 48 weeks ]
  4. Difference in the number of ranibizumab injections received by patients who have received at least three injections. [ Time Frame: Between weeks 12 and 48 ]
  5. Change in Central sub-field thickness over time [ Time Frame: 12, 24,36 and 48 Weeks ]
  6. Pattern of injections given over the period of 48 weeks in both arms. [ Time Frame: 48 weeks ]
  7. Adverse events rates [ Time Frame: 48 months ]

Other Outcome Measures:
  1. Compliance of wearing the mask [ Time Frame: 48 weeks ]
  2. Changes in sleep pattern. [ Time Frame: 48 months ]
