简要总结

The aim of the evaluation is to compare and observe the efficacy of two different light emitted levels of Noctura 400 sleep mask on 300 patients with early DMO over a period of 12 months. 150 patients will be assigned randomly to each group. One group will receive the standard treatment of 2 scotopic trolands and the other will receive the lower level of light being tested which is 0.03 scotopic trolands. The results of the two groups will be compared. Results will be compared the efficacy of treatment in the two arms and their significance in the treatment of diabetic macular edema and to corelate with the level of compliance in each arm. Proposing that a low level of light will provide similar efficacy with better compliance

In this study the analysis will focus on the change in key measures of diabetic macular oedema and the classification level of diabetic retinopathy. Observations will also include the need to administer standard treatments in parallel with mask use.

An interim analysis will be carried out at 6 months, to ensure the study is powered correctly and to allow early publication of data if a strong efficacy signal is significant.

主要目的
随机平行对照
盲法
The randomization sequence will be generated using a computerized randomization table kept centrally by a research assistant. All patients and investigators will be masked to the treatment allocation group. Assessors performing the follow-up assessments also will be masked to the patient allocation group.
