Before and After CPAP

Caption

These images are labeled to show which was taken before the patient had CPAP treatment for sleep apnea, and which was taken after. In the study, independent raters who didn't know which was which were able to tell the difference two-thirds of the time. A detailed analysis of these and other images also showed less redness and forehead puffiness after treatment -- though no improvement in dark circles or puffiness under the eyes.
