A miniature compliance monitor for eyedrop medication
M. A. Kass, D. W. Meltzer and M. Gordon
We developed an eyedrop medication monitor that electronically records the
date and time of each medication administration over a six-week period. It
records a medication usage in a 15-minute interval when the cap is removed
from the bottle and the bottle is inverted. The electronic components
housed inside the bottle weigh 7.5 g, including the batteries, and the
total volume of the circuit is 7.5 cc. The monitor resembles commercially
available 30-mL eyedrop bottles in size, shape, and weight. The monitor is
accurate when tested against known patterns of usage. The electronic
eyedrop monitor should be useful in assessing compliance with eyedrop
medications.
