Recently in the Archives of Ophthalmology, Dr. Mark J. Schoenberg1 described a two hook diathermic cutting current electrode for the treatment of separated retina. This at first glance was so similar to my double-pronged short-stop electrode which was exhibited at the September meeting of the Academy of Ophthalmology and Otolaryngology while Dr. Schoenberg was traveling in Europe that it seems worth mentioning. I did not know of any other work on a similar device until the aforementioned article was published.
My device, shown in the accompanying photograph, differs in several details. The prongs are 2 mm. apart but can be bent to 2.5 mm. or 3 mm. apart. Each prong has a step-stop, filed in, so that it will not penetrate far enough under 100 milliamperes of diathermic current to permit the supporting arms to touch the sclera, thus reducing scleral damage and alteration of the
