The separation between the choroid and the retina whichappears in the preparation, is artificially produced ; but supposingit not to exist, it will be seen that there must have been duringlife a very considerable swelling of the optic disc. Silniisch* gives a similar representation in a case of neuro-retinitis caused by brain tumor. Most cases of decided swelling of the optic disc present uponanatomical examination undoubted inflammatory changes. In theneighboring retina there is frequently a hypertrophic developmentof the connective tis
