Punctal ectropion test suture.
We describe here a technique designed to temporarily remove puncta from the lacrimal lake. The "punctal ectropion test suture" (PETS) temporarily rotates the punctum away from the globe, thus interfering with normal tear outflow. The test suture may be used wherever the value of closure of the punctum is contemplated. It is especially useful in symptomatic patients with borderline normal tear outflow.
