A 40-year-old patient underwent Aurolab aqueous drainage implant in the right eye 1 month back. The tube was ligated with single 7-0 polyglactin suture. IOP was 28 mm Hg. The ridge of the plate was well delineated [Figure 1]a with a flat bleb indicating that the tube has not opened yet. When examining a patient with non-valved implant, this simple way of looking for the visibility of ridge will help us understand if the bleb has matured. If a previously well-delineated ridge gets obscured in the next visit [Figure 1]b, suture must have dissolved and the tube opened.
