title: A scleral marker with additional uses.
abstract: We use a scleral marking pen to indicate the position of a retinal break. Although its primary purpose is to mark the localizing impression of the cryosurgical probe, the pen can be modified to serve as a localizer, as a measuring device, and as a buckle simulator.
