The purpose of this study is to determine if an eye drop video monitoring device can
accurately assess (as compared to a patient's own log or a proprietary software) the exact
amount and time of eye drop delivery to a patient's eye. It is our belief that the
experimental device will help patients to be more compliant by: 1) providing a viewable
format so patients can see what is happening when they are applying their drops 2) providing
greater accuracy to doctors regarding when and how much medication was used 3) providing
greater accuracy to doctors and patients regarding how much medication was actually delivered
to a patients eye.
