A detailed study of the ocular changes produced by temporal lobe tumors has been made in order to ascertain the frequency of correct localization from an ophthalmologic standpoint. Cushing's1 report that perimetric field defects in temporal lobe lesions were of paramount diagnostic value, localizing definitely the site of thirty-three of thirty-nine tumors of the temporal lobe, was a further stimulus to this study.
In a series of 168 cases of certified cerebral tumors examined in the Mayo Clinic during the last five years, sixty were located in the temporal lobes. In all but three of these cases, operation was performed; and in these three, the location was diagnosed correctly, as proved by necropsy. There were fifty-three cases of infiltrating gliomas, three of dural endotheliomas, two of calcified hematomas, and two of angiomas.
The ocular changes may be divided into four groups: (1) changes of visual acuity; (2)
