Scientific title | The effect of prevention of Dark Adaptation (DA) on the progress of Diabetic Macular oEdema (DME) |
Study acronym | DA and DME |
Study objectives | By reducing the metabolic demand of retinal rods, which is maximal in dark adaptation, retinal hypoxia in diabetic eye disease will be reduced, and the progress of diabetic eye disease reversed. |
Ethics approval(s) | Approved by Kings College Hospital Research Ethics Committee (REC) in February 2009 (ref: 08/H0808/198) |
Health condition(s) or problem(s) studied | Diabetic retinopathy |
Intervention | Patients will sleep wearing a device ('light mask') that illuminates one (closed) eyelid. The eye is chosen at random. The other eye acts as control. Each patient will be treated for 6 months |
Intervention type | Other |
