I use it to measure areas of GA in a clinical trial but I wish there was a way to control the follow-up measurements. There is no way to measure the sensitivity of the selected area as you dial it up with the mouse wheel. I don't know if the final setting is higher or lower than the previous visit. It is not an exact measure and it would be nice to know how much change is considered significant. Kirsten Kirsten Locke, RN, CRA, FOPS.
