A Real-World Single-Centre Study of Patients with Diabetic Macular Oedema Who Wore a Home-Use Sleep Mask (Noctura 400) for One Year

Table 3

The mean and median OCT measurements for the maculae of the 24 patients who completed the study. The table includes values for each of the 9 macular zones and a best improvement for all zones determination. Parametric (paired t-test) and nonparametric (signed-rank test) stats testing have been applied.

Best of all zones (μm)	−13.26 (14.17)	−8.5 (−16–4)	<0.0001	<0.0001
Best of inner ring zones (μm)	−10.52 (13.82)	−5.5 (−15–3)	<0.0001	<0.0001
