RETINAL DETACHMENT

Abstract

The attempt to localize retinal lesions is not new. In 1882, von Graefe¹described his method of localizing a retinal cysticercus cyst. He also invented a new type of ophthalmoscope to be used in such cases. His method embodied several principles that are in use today. Accurate localization of a retinal tear is a difficult procedure. The reason is obvious. One is working with many variable factors, e. g., the cooperation of the patient, the possible movement of the detached retina containing the tear, the length of the globe and the surgeon's judgment in estimating distance. No method, therefore, is free from error. At the present time various methods are employed. Schoenberg,²in a recent article, described the method that Gonin employs. He locates the retinal tear with the ophthalmoscope, and ascribes it to a meridian corresponding to the hour hand of the clock. A black silk suture
