Actual (reported)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.
