The toxic amblyopias: their classification, history, symptoms, pathology, and treatment . Visual fields of a diabetic, with central amblyopia; patient also with Plate I The central shaded area is the scotoma for red.(Nettleship and Edmunds.) Plate I illustrates the lesions found in the case ofcentral amblyopia by Mr. Nettleship and Dr. WalterEdmunds. Plate I., fig. 1. Transverse section of the optic nervea little in front of the point of entrance of the centralartery and vein. The outer sheath is wanting. A patch,somewhat sector-shaped (a), extending from the innersheath of the nerve almost to the central vessels, showsa general increase of nuclei both in the fibrous septawhich separate the bundles of nerve fibres and in thosebundles themselves. The inner sheath at the same partis thicker than at any other part. There is considerableincrease of nuclei in the fibrous septa to the left (in thefigure) of the patch (a), showing probably a commencinginvasion of that part of the nerve by the morbid process,x 20.
